This genus, which differs from Capua only by the absence of the costal fold in ♂, has not been hitherto known from New Zealand, but is well represented in Australia.
Epagoge cyclobathra, n. sp.
♂ ♀. 16–18 mm. Head, palpi, and thorax rather dark fuscous. Abdomen pale grey, Forewings elongate, suboblong, costa moderately arched, apex obtuse, termen hardly rounded, rather oblique; fuscous, slightly purplish-binged, sprinkled with dark fuscous, towards middle of costa suffused with dark ashy-fuscous, towards termen mixed with reddish-ochreous and strigulated with dark fuscous; basal ⅖ whitish-ochreous, marked with several deeper ochreous striÆ, outer edge curved; within this patch an irregular dark-fuscous streak from base of dorsum along costa to ¼, thence proceeding as a curved transverse streak to sub-median fold: cilia grey, with dark fuscous median line. Hind wings light grey; cilia whitish-grey, with darker subbasal line.
Invercargill, in December and January (Philpott); two specimens.
Trachybathra, n. g.
AntennÆ in ♂ moderately biciliated. Palpi moderate, porrected, rough-scaled above and beneath. Thorax smooth. Forewings with rough scales at base, in ♂ with costal fold; 2 from ⅔, 7 and 8 stalked, 7 to termen, 11 from middle. Hindwings with vein 4 absent, 6 and 7 stalked.
Allied to Capua, from which it differs by the rough basal scales of forewings, and the absence of vein 4 of hindwings.
Trachybathra scoliastis, n. sp.
♂. 18 mm. Head, palpi, and thorax brownish irrorated with grey-whitish and dark fuscous. Abdomen fuscous. Forewings
elongate, hardly dilated, costa slightly bent before middle, apex obtuse, termen faintly sinuate beneath apex, bowed, oblique; pale brownish, partially suffused irregularly with whitish, costa and dorsum strigulated with dark fuscous; outer edge of basal patch indicated by a blackish line in disc, obsolete towards extremities; an irregular incurved fuscous streak marked with black from ⅖ of costa to below middle of disc, followed by whitish suffusion; an irregular dark-fuscous spot above tornus, and some dark-fuscous strigulÆ towards lower part of termen: cilia grey-whitish mixed with dark grey. Hindwings fuscous, strigulated with darker; some undefined ochreous-yellowish suffusion in centre of disc and towards costa in middle; cilia pale grey, with dark-grey subbasal line.
Lake Wakatipu (Hudson); one specimen.
Pyrgotis tornota, n. sp.
♂. 18 mm. Head and thorax pale ochreous sprinkled with dark ferruginous. Palpi 2½, whitish-ochreous, irrorated wit dark ferruginous. Abdomen pale whitish-ochreous. Forewings elongate, posteriorly somewhat dilated, costa strongly arched towards base, faintly sinuate in middle, posteriorly almost straight, apex obtuse, termen concave, little oblique; reddish-brown, suffusedly mixed with pale leaden-grey, and strigulated with whitish-yellowish; a few minute dots of blackish scales, especially on dorsum; a moderately broad curved darker streak, suffusedly irrorated with yellow-ochreous, from ⅓ of costa to below middle of disc, thence curved evenly upwards, confluent towards costa with a round similar blotch on middle of termen, so that the ground-colour appears to form a narrow whitish-edged projection upwards between them: cilia reddish-brown, darker towards apex, tips whitish-ochreous. Hindwings whitish, with a few grey strigulÆ on dorsal half; cilia whitish.
Invercargill, in August (Philpott); one specimen. The whitish hindwings are a special characteristic.
Adoxophyes conditana, Walk.
I have received from Mr. Philpott three examples of a curious melanic form of the male of this-species, stated to be common near Invercargill. The forewings are mainly suffused with dark purplish-grey irrorated or strigulated with blackish, except some small variable whitish spots towards middle of dorsum and sometimes towards apex and termen; whilst the hindwings are densely irrorated with blackish. I at first thought it a distinct species, but after careful comparison with my long series of varieties of this extraordinarily variable species am satisfied that it is only a melanic southern form; I have not
however, yet seen the corresponding females. Several other species from Invercargill show the same tendency to melanism, which should be borne in mind when considering insects from that region.
Cacoecia acrocausta, n. sp.
♂. 19–21 mm. Head and thorax brownish-ochreous or yellow-ochreous. Palpi. 3, fuscous, externally suffused with ferruginous. Antennal ciliations 1 ½. Abdomen whitish-ochreous, beneath ferruginous, and tuft mixed with dark grey. Forewings elongate-triangular, costa slightly arched, apex obtuse, termen rounded, little oblique; whitish-ochreous or yellow-ochreous, with scattered blackish-grey strigulÆ, basal ¾ more or less tinged or suffused with brown; costal edge ferruginous: cilia whitish-ochreous, on upper half of termen dark grey, on costa yellowish-ferruginous. Hindwings ochreous-whitish, strigulated with pale grey, more distinctly towards base; cilia ochreous-whitish.
♂. 22 mm. Head and thorax whitish. Palpi 3 ½, ochreous-whitish, externally fuscous-sprinkled. Forewings more elongate than in ♂, ochreous-whitish, sprinkled with very pale fuscous; central fascia indicated by an undefined grey very zigzag shade; a small grey spot towards termen in middle: cilia whitish-ochreous, becoming fuscous on upper part of termen. Hindwings as in ♂.
I took a male and female together at Christchurch in September, but had not ventured hitherto to describe them; I have, now received four additional males from Mr. Philpott, taken at Invercargill, where the species is common in October and November. It is allied to excessana, but quite distinct.
Cacoecia orthropis, Meyr.
Examples from Invercargill sent by Mr. Philpott have the forewings much greyer than Christchurch and Wellington specimens, and the hindwings are also grey; they appear to constitute a geographical form only, and to afford an instance of the tendency to a darker colouring mentioned above.
Tortrix molybditis, n. sp.
♂. 12 mm. Head and palpi rather dark fuscous, palpi 2. Antennal ciliation 1. Thorax dark glossy leaden-fuscous. Abdomen dark fuscous. Forewings elongate, posteriorly dilated, costa gently arched, apex obtuse, termen straight, rather oblique; rather dark glossy leaden-grey; markings blackish-fuscous; four small spots on costa alternating with principal markings; a stria marking outer edge of basal patch, strongly angulated in
middle; a small spot of pale - yellowish projecting scales on dorsum neat base; upper half of central fascia well marked, lower half obsolete; a small triangular costal patch, from near which proceed two irregular striae to tornus and lower part of termen, edged with a few pale-yellowish scales: cilia dark fuscous, tips paler. Hindwings dark fuscous; cilia pale - greyish, with dark-grey basal line.
Wellington (Hudson); one specimen. Very distinct; has some superficial resemblance to Dipterina hemiclista, but easily distinguished by the short antennal ciliations.
Eurythecta paraloxa, n. sp.
♂. 12–13 mm. Head and thorax whitish-ochreous, more or less suffused with ferruginous, with a few black scales. Abdomen dark fuscous, apex pale ochreous. Forewings elongate, rather narrow, costa somewhat arched anteriorly, apex obtuse, termen somewhat rounded, oblique; vein 7 present; ochreous-whitish, more or less suffused with yellow-ochreous, palest on costa; markings yellow-ochreous or ferruginous, variably mixed with dark fuscous; basal patch darkest towards outer edge, which is oblique, rounded - prominent in middle, more or less-excavated beneath this; central fascia moderate, anterior edge nearly straight, posterior edge irregularly prominent below middle, so as to appear concave on upper half; four small spots on costa posteriorly, first three sometimes confluent into a small triangular blotch; an irregular blotch along termen: cilia ochreous-whitish, more or less distinctly barred with dark fuscous. Hindwings dark grey; cilia grey.
Invercargill, common on sandhills in January (Philpott); three specimens. This species differs from the other two in having vein 7 of forewings present; but as it possesses the other characteristic structural points of the genus, and is obviously nearly allied in all respects, it seems unnecessary to form a new genus for its reception. The genus is a development of Proselena, and the present species is an early form of it.
Prothelymna niphostrota, n. sp.
♂. 15 mm. Head whitish. Palpi, thorax, and abdomen pale fuscous. Forewings elongate, costa moderately arched, apex obtuse, termen slightly rounded, oblique; white; basal patch pale fuscous, marked with spots of blackish irroration; dorsal half from this to tornus marked with coarse grey strigulÆ irrorated with black; an oblique grey patch on middle of costa; a smaller dark-grey spot on costa at ¾; a grey apical patch, marked with coarse blackish-grey strigulÆ, and extended as an irregular subterminal stria to tornus: cilia whitish, round
apex greyish-tinged and spotted with blackish irroration. Hindwings pale grey, veins partially dark grey; cilia grey-whitish.
Invercargill, in January (Philpott); one specimen. This, the second known species of the genus, is easily known from the other by the white ground.
