Art. XLII. — Descriptions of New Zealand Lepidoptera. 

 By E. Meyrick, B.A., F.R.S, 

 Communicated by G. V. Hudson, F.E.S. 



I AM again enabled, by the kindness of my correspondents Messrs. G. V. 

 Hudson and A. Philpott, to describe some interesting' new forms of 

 Lepidoptera, including two new genera of remarkable peculiarity. 



TORTRICIDAE. 



Tortrix melanosperma n. sp. 



(J. 21 mm. Head, palpi, and thorax light grey, palpi moderate, 

 ascending. Autemial ciliations 1. Abdomen pale ochreous-grey, anal tuft 

 ochreous-whitish. Forewings elongate, eosta moderately arched, without 

 fold, apex tolerably pointed, termen nearly straight, rather strongly ob- 

 lique, pale grey, with scattered black scales tending to form rows ; costa 

 rather broadly suffused with whitish ; a conspicuous black dot in disc at f : 

 cilia whitish-grey. Hindwings light grey : cilia whitish-grey. 



Arthur's Pass, 3,000 ft., in December (Hudson) ; one specimen. Allied 

 to indigestana. 



Harmologa trisulca n. sp. 



(J. 29-31 mm. Head, palpi, and thorax with ferruginous hairs, 

 beneath these dark fuscous ; palpi 3. Antennae without ciliations. 

 Abdomen dark fuscous, segments margined with grey-whitish scales, anal 

 tuft grey- whitish. Forewings elongate, moderate, posteriorily dilated, costa 

 gently arched, with narrow fold on basal sixth, apex obtuse, termen straight, 

 little oblique, rounded beneath ; deep ochreous-yellow ; a broad pale 

 ochreous-yellowish median streak from base to f , suffused beneath and 

 posteriorly, sharply defined above, costal area above this wholly deep 

 red-brown, costal edge suffused with dark leaden-grey, dorsal third of wing 

 suffused with ferruginous : cilia light leaden-grey, basal third with yellowish 

 scales, tips whitish. Hindwings dark grey, towards apex and termen 

 blackish-tinged : cilia grey-whitish, basal third grey. 



?. 33 m. Head and palpi pale ochreous, palpi 4. Thorax with 

 pale-ochreous hairs, blackish-scaled beneath. Abdomen whitish-ochreous. 

 Forewings elongate, moderate, slightly dilated, costa gently arched, apex 

 obtuse, termen faintly sinuate, little oblique ; pale ochreous-yellowish ; 

 two dark-fuscous dots in disc before and beyond middle, just below upper 

 margin of cell : cilia whitish, basal tliird pale-yello-^ish. Hindwings pale 

 whitish-yellowish sprinkled with grey, dorsal f suffused with grey : cilia 

 yellow- whitish. 



Arthur's Pass, 3,500 ft., in December (Hudson) ; four specimens. The 

 (J is much like siraea, but a larger and finer insect, more brightly coloured, 

 the costal area of forewings very much darker than dorsal, the head and 

 thorax witliout grey suffusion, whilst in siraea the costal and dorsal areas 

 are nearly the same in colour, the costal edge distinctly whitish, and the 

 median streak forms a distinct projection along fold; the ?, however, are 

 entirely dift'erent, siraea having grey-whitish forewings and white hindwings, 

 whilst this species is much more like aenea. A <J sent by Mr. Hudson from, 

 the Hunter Moimtains is true siraea.
