D. hudsonica n. sp. (Figs. 1, 7, 8.)

A rather large species with pointed vertex and pale tegmina with a broad chocolate band along the outer border of clavus.

♀. Vertex less than twice as broad as medianly long. Irregularly and coarsely corrugated and punctured. Median suture distinctly marked by several ridges and depressions. Fore-border, as usual, edged narrowly with shining fuscous; acutely rounded. Eyes variegate with fuscous and grey, anterior portion wholly fuscous. Ocelli pinkish with pale centres, each ocellus somewhat on the side of a wide and fairly deep depression. Disc of vertex shining yellowish-brown inclining to olivaceous. Edge between vertex and frons abrupt and fairly acute, but passing immediately ventrad into a rounded curve.

Pronotum about as long as vertex or very slightly shorter; anterior half with almost smooth surface, but with median longitudinal line flanked on each side by a transverse rounded callus, which forms on each side the anterior border of a slight depression. There is a deeper depression lateral to each callus. Posterior portion transversely striate with wide grooves containing occasional fuscous punctations. Disc of pronotum concolorous with vertex. Hind-border slightly emarginate and sinuate with no trace of angularity.

Scutellum large, with a roundly curved anterior surface of pale olivaceous clouded faintly with fuscous, and separated from sharp brownish apex by a curved transverse depressed line with its convexity cephalad. Disc of scutellum with faint indications of irregularly concentric striation. As long as or a little shorter than pronotum.

Abdomen olivaceous, with segmental margins paler; very shining.

Tegmen coarsely punctate, especially along veins. Corium almost immaculate, whitish except for a pale-brownish suffusion on costal portion of basal third, and a few chocolate flecks about middle of claval suture and near bases of ante-apical cells. Clavus with anal angle and a wide irregular band reaching in width more than half-way to suture, dark brown or chocolate; remainder colourless.

Wings with the cells speckled with fuscous, but not heavily enough to mar the transparency. Veins clear.

A second locality is Gollan's Valley, Wellington, also near the sea. I have not found it on any other food-plant, nor even on the same food-plant in other similar localities in the same district. The males appear to be rare: I have only one male among some twenty-eight females; but as my specimens were nearly all collected early in October it is quite possible that the females had appeared first and the males had not reached their maximum of abundance.

As has been noticed in connection with Paradorydium westwoodi and Cephalelus leptocarpi n. sp., the insect is frequently (always, in my experience) confined to a very small patch, though there may be large areas of the food-plant, which grows often in pure associations, in the immediate vicinity.

The adults are rather sluggish, but are capable of leaping some distance, though the posterior legs are apparently very little specialized for this purpose.

The jointed rush (Leptocarpus simplex) has smooth green or reddish internodes, while the fairly frequent nodes are surmounted and partly surrounded by rougher greyish or brownish sheaths. It is to these sheaths the leaf-hoppers bear such an extraordinary resemblance. The insect always rests with its long axis parallel to that of the stem—a position necessary for “purposes” of mimicry, but probably assumed for the sake of comfort.

Occasional examples are parasitized by large, long-legged scarlet mites with long hairs. In one case three of these mites were fastened tightly to the base of one of the tegmina, which, apparently as a result of their sucking, had curled up and twisted like the half of a dried pea-pod. More commonly only one mite is found, and that tucked beneath the tegmina, the abdomen of the Cephalelus being then often slightly deformed, but no other effects apparent.

The nymphs of all ages are found on the food-plant with the adults. They are almost uniform pale brown, with a very indistinct pallid median dorsal line, and a head much less produced than that of the adult. I have not yet succeeded in finding the eggs.

being taken from the net. The species frequenting ground-herbage and short grass are with difficulty obtained thus, and then only by very close sweeping. Such species apparently live very near the ground, well below the free tops of the plants which the sweeping-net reaches. The only certain way of securing these is by capturing them individually with a small net about 3 in. in diameter. This method, necessitating kneeling, as it does, has its disadvantages, but, on the other hand, much more can be observed of the habits of the insects than in the random processes of beating and sweeping. In swampy country, with pools of water, many leaf-hoppers are to be found hopping on the surface of the water, on to which they have come from their adjacent host-plants, and many more can be sent to join them by shaking and kicking the herbage surrounding the water, from which the insects are collected with comparative ease. It is of the utmost importance that records of the food-plants be kept wherever possible.

For killing Typhlocybines and all other leaf-hoppers a cyanide-bottle or small tube, with a smaller tube or quill through the cork, in coleopterist-fashion, is most convenient. It is highly essential that the inside of the bottle be kept dry, otherwise the insects will stick to the sides and to one another and suffer irreparable damage. If the cyanide-bottle has been prepared by the plaster-of-paris method, practically no care will maintain a perfectly dry interior. Pieces of dry potassium cyanide should be placed in the bottom of a tube, covered by several layers of blotting-paper, and then by a tightly-fitting cork, slightly perforated to allow the fumes to pass. Above this cork, which should be forced tightly down on the cyanide, place a piece of blotting-paper and a little crumpled tissue-paper. Several such tubes should be at hand, and if they are kept only for leaf-hoppers no moisture will collect in them.

For permanent preservation Typhlocybines should be gummed across the apex of card triangles, so that the underside of at least the head and genitalia may be examined, or they may be pinned through the scutellum with the finest pins used by micro-lepidopterists. For correct determination a large series is convenient, some of which should be mounted to display the tegmina and wings. On collecting-excursions of long duration they may be kept indefinitely in small screws of tissue-paper; but specimens to be mounted with extended wings must be set as soon as possible after death.

Except in the case of such economically important species as the apple leaf-hopper (Empoasca mali Le Baron), the rose leaf-hopper (Typhlocyba rosae Linn.) and the grape leaf-hopper (Erythroneura comes Say) the biology of the Typhlocybinae is but little known. The first of the above-mentioned species, the American apple leaf-hopper, not only inflicts serious damage on the foliage of apple, potato, bean, and lucerne, but also actually transmits two diseases, fireblight (Bacillus amylovorus) of pomaceous fruit-trees and hopper-burn of potatoes. Even in the cold winters of North America, specimens of the apple leaf-hopper frequently winter in the adult state. In New Zealand, specimens of Erythroneura zealandica n. sp. have been taken after midwinter, and, considering our milder climate, it is quite possible that many of our species are carried over the winter as imagines. The evergreen nature of our bush would help such species as find their host-plant there.

In New Zealand we have one species ranking as a serious apple pest, and probably as a carrier of fireblight; another of very wide occurrence

on a variety of field-crops and pasture-plants, but not yet convicted of serious damage; and a third species, an endemic one, inflicting the same damage on Coprosma grandifolia as the introduced Typhlocyba australis (Frogg.) on apple.

The Typhlocybinae are among those leaf-hoppers parasitized by minute wasps of the family Dryinidae. None, however, have yet been successfully reared from New Zealand species, nor have I found affected leaf-hoppers very numerous. Bird enemies probably account for very few, although in America these small leaf-hoppers are said to form a certain proportion of the food of humming-birds. Finally, Mr. Muir informs me that egg parasites are generally common.

The structural characters of the Typhlocybinae render them probably the most homogeneous and easily recognized subfamily of the Cicadellidae. In the tegmen the three longitudinal veins of the corium—the radius, media, and cubitus—run without branching to the apical cells, so that no ante-apical cells are formed. The 1st A corresponds almost exactly with the claval suture (Cu₂ not present) and the third with the claval margin, leaving only a single vein on the disc of the clavus—a character shared (according to McAtee) by no other Auchenorrhyncha. The ocelli are almost always difficult to distinguish, and are often lacking. Long elliptical areas about the middle of each costa bear a thick circumscribed coating of a wax-like substance. The detachable pruinose flakes are known as the “costal plaques.” Some species—e.g., Erythroneura cyathea n. sp.— possess them well developed; but they are by no means a specific character, being subject to individual variation.

Important generic distinctions are found in the venation of tegmina and wings, the main characters being very constant; but the details vary with the individual. Good specific characters are found in the genitalia.

The Typhlocybinae are to be considered among the most highly evolved of the Cicadellidae, their specialization consisting in a simplified venation probably derived from a much more complex type.

The New Zealand species at present collected include six species, in three genera. Of these six species, five are new, and one apparently introduced from Australia, although Mr. Muir informs me that it is by no means certainly endemic there. I am indebted to Mr. Muir for kindly reading the manuscript of this subfamily and for valuable advice and help.

I have followed McAtee in the generic nomenclature. Typhlocyba is often used by other authors where McAtee uses Eupteryx, of which Typhlocyba is in part a synonym. Under such a system my Typhlocyba would be Empoa.

In connection with this key it should be noticed that, according to Osborn, Gillette, and Woodworth, all those species in which the wing has no submarginal vein and the first two veins unite before reaching the margin, so that only three veins attain the margin, fall into the genus Typhlocyba Germar. Only the African genus Molopopterus Jacobi, which is easily distinguished by other characters, is excepted.

as wide as base of vertex between eyes. Apex of scutellum acute. Male genitalia short and abrupt; claspers bent abruptly, tips almost reaching the dorsal line of abdomen in lateral view. Female genitalia—ovipositor short, tipped with fuscous, and furnished with seven or eight very stout short bristles. Ninth or last unmodified abdominal tergite abruptly truncate.

Total length, 2·7 mm. (male and female).

This is the common grass-frequenting species, found in large numbers in any grassy places, whether the grass be introduced pasturage or native tussock. It is also common in all stages on tauhinu, or cottonwood (Cassinia leptophylla). There is considerable colour-variation, those from Wanganui being yellowish, the common Wellington specimens greenish, and those taken on tauhinu in various localities of the Wellington district a peculiar greyish-green resembling that of the food-plant. I can find no accompanying structural differences. The various forms seem to grade into one another. A somewhat dilapidated female taken on mangrove at Whangarei appears to belong to this species. Typical specimens have been collected from manuka (Leptospermum scoparium). While making the above description wide enough to include all the forms here enumerated, I have retained the Cassinia forms as types.

Erythroneura kiekie n. sp. (Figs. 30, 40, 43.)

♂♀. Whole upper surface bright yellow, thoracic nota often orange. Eyes blackish (eye-colour is of little taxonomic value, as it may vary from whitish to black in the two eyes of the same individual). Tegmina yellow, the membrane a little paler, but not hyaline. Wings hyaline. Underside uniform pale yellow. Claws, except posterior ones, black. Ovipositor pale-brownish. Rostrum tipped with brownish. Upper surface of abdomen blackish. Vertex very broadly rounded anteriorly; not twice as wide as medianly long. Median longitudinal suture distinct. Pronotum rounded anteriorly, and considerably excavated posteriorly—the anterior portion paler and somewhat depressed, posterior half shining and darker yellow. Scutellum a little wider at base than base of vertex between eyes; transverse line about half-way, to which the sides gradually slope from base, beyond which transverse line (caudad) they rapidly narrow to the very acute and somewhat elevated apex.

Total length, 3·7 mm. (male and female).

This handsome species has been taken only on kiekie (Freycinetia Banksii), to which it may possibly be confined, and on which it occurs in considerable numbers.

Erythroneura cyathea n. sp. (Figs. 31–33, 38, 44.)

♂♀. General colour pale yellowish- or greenish-white or practically colourless. Vertex pallid, tumid, produced, punctate, with occasionally two brownish patches varying from faint smudges to distinct spots. Eyes variegate. Pronotum with an anterior smooth, collar-like portion;

remainder finely transversely striate. Humeral angles produced, truncate, covering base of tegmina. Pronotum and tegmina very pale yellowish-or greenish-white or practically colourless. Pronotum narrowly rounded anteriorly, and very slightly excavated posteriorly. Wings milky. Base of scutellum considerably wider than posterior border of vertex. Scutellum with depressed anterior portion and slightly elevated acute apex. Triangular area on each side of base of scutellum often brownish. Under - surface pale creamy-white. Claws fuscous. Frons very tumid, with dull frosted surface. Genitalia of both sexes pale. Upper surface of abdomen white.

Total length, 3·4–4 mm. (male and female).

In one well-marked variety (No. 175) the colour is a somewhat brighter yellowish, and the hind border of pronotum, disc of scutellum, extreme edge of radial margin of tegmina, and to a less extent the membrane of tegmina are suffused with fuscous.

In a second variety (No. 185, one specimen) the brown colour is confined to the two basal triangular spots of the scutellum and to its sides, forming a very distinct dorsal V. As I can find no accompanying structural peculiarities, and as the faint brown markings sometimes present in the more typical specimens vary greatly in intensity, I am constrained to regard this as nothing more than a colour variety comparable to those of the common Cercopid Philaenus trimaculatus (Walker).

This variable and common species occurs among mixed undergrowth in ordinary rain-forest. With specimens collected by beating and sweeping it is difficult to be sure of the food-plants, but one is the tree-fern Cyathea dealbata, and another, on which all stages can be collected, is Coprosma grandifolia. Specimens from the tree-ferns are uniformly and constantly more whitish, and the types have been selected from these.
