P. nefaria.

There is a mistake in my former paper in Trans. N.Z. Inst., xxxiii., p. 59. There is no yellow spot at the base of the wings.

P. aurea, sp. nov.

Frontal band black; vertex black, with blue reflections; sides of the face golden-yellow, with a reddish-brown spot on each side just below the lower fronto-orbital bristles. Antennæ, antennal fovea, and proboscis black. Thorax, scutellum, and abdomen brilliant metallic-blue. Legs black. Squamæ greyish. Wings colourless; the veins black, the costa fulvous at its base. First posterior cell open. No discal setæ; marginal setæ on the third and fourth segments only. Length, 7 mm.; wing, 7 mm.

Longbeach, November, 1902.

P. marginata.

This species has a brown spot on each side of the face. The individuals with a green thorax I make into a separate species, as follows:-

P. exitiosa, sp. nov.

Frontal band and antennæ black, as also are the palpi and proboscis. Vertex dark-grey. Cheeks black, with silvery pubescence. Thorax metallic-green; the abdomen deep-blue. Scutellum blue, margined with ferruginous. A rather obscure fulvous spot at the base of the wings. Legs black. Length, 8–9 mm.; wing, 6 ½–7 ½ mm

Longbeach, November, 1902.

There are 3 sterno-pleural macrochætæ.

P. tecta, sp. nov.

Frontal band dark reddish-brown; vertex and sides of the face yellowish-white, with a spot of reddish-brown on each side about the middle of the antennal groove. Antennæ, palpi, and proboscis piceous. Thorax grey, with three short black lines on the fore part. Scutellum dark-fulvous, the base grey. Abdomen greyish-brown, with white tessellations on each side. Legs blackish, the tibiæ dark-fulvous. Squamæ white. Wings colourless; the veins blackish-brown. The first posterior cell completely closed. Three sterno-pleural macrochætæ. Length, 7 mm.; wing, 5 mm.

Wellington and Christchurch.

P. casta, sp. nov.

Frontal band dark reddish-brown; vertex and sides of face silvery-white, without any spot. Antennæ and proboscis piceous. Thorax greyish-brown, with some obscure black lines

on the fore part. Scutellum fulvous, with a grey base. Abdomen dark greyish-brown, with white tessellations on the sides. Legs blackish, the tibiæ dark-fulvous. Squamæ white. Wings slightly tinged with brown near the base; the veins dark-brown. The first posterior cell barely closed. Length, 7 mm.; wing, 5 mm.

Christchurch.

P. inconspicua, sp. nov.

Like P. tecta, but no spot on the side of the face, and the first posterior cell slightly open. Third joint of antennæ not much more than twice the length of the second. Length, 7 mm.; wing, 5 mm.

Christchurch.

Described from a single specimen.

P. orasus.

The sides of the face are yellow, the antennal groove white. Legs black. Length, 7 mm.; wing, 5 mm.

P. clathrata.

This species differs from P. orasus only in having red spots on the sides of the abdomen, and there are many intermediate varieties of which it is doubtful to which species they should be referred.

P. efferata.

Frontal band dark reddish-brown; the vertex yellowish-white, with black shadows; sides of the face yellowish-white, with a broad brown spot on each side half-way down the antennal groove. Femora tawny; tibiæ and tarsi black. Often a fulvous spot on the side of the second abdominal segment. Three sterno - pleural macrochætæ. Length, 10 mm.; wing, 7 ½ mm.

P. fulvipes, sp. nov.

Like P. efferata, but the tibiæ and tarsi fulvous. Length, from 8 mm. to 10 mm.

P. brouni, sp. nov.

Vertex, face, and antennæ black. Thorax and scutellum dark-fulvous. Abdomen pale-fulvous. Legs black. Wings colourless. Length, 5 mm.; wing, 4 mm.

Maketu. Captain Broun.

A single damaged specimen, but very distinct from any other.

P. funesta.

There is a brown spot on each side of the face.
