Common at Hamilton, Wellington, and Christchurck, in January and 

 March. 



34. Streps, zopherana, Meyr. 

 (Strepsiceros zopherana, Meyr., Proc. Linn. Soc. N.S.W., 1881, 688.) 



Parva, alis ant. griseis, albido-sparsis, vitta subcostali nebulosa inter- 

 rupt nivea, subtus partim nigro-marginata, macula parva supra angulum 

 analem nigra ; post, griseis. 



Male, female. — 11-12^ mm. Head and thorax grey irrorated with 

 white, head sometimes almost wholly white. Antennae of male notched at 

 •J from basal joint. Forewings very narrow, costa slightly arched, apex 

 produced, hindmargin sinuate, very oblique ; dark grey, irrorated with 

 whitish, sometimes strigulated with dark fuscous ; costa very obliquely 

 strigulated with blackish-grey ; a rather broad ill-defined white streak 

 beneath costa from base to apex, crossed by an oblique dark grey fascia-like 

 streak before middle, and three or four slender dark grey very oblique 

 strigulae between that and apex ; middle of disc somewhat suffused with 

 blackish ; an ill-defined black spot above anal angle ; a short black line 

 bordering subcostal streak beneath towards apex ; generally a row of about 

 three ill-defined black dots above anal angle towards hindmargin, preceded 

 and followed by an obscure silvery- metallic line : cilia dark grey, paler 

 towards anal angle, with a blackish apical spot, costal cilia white. Hind- 

 wings thinly scaled, grey, darker at apex ; cilia pale grey, with an indistinct 

 darker line near base ; veins 3 and 4 coincident. 



Variable in distinctness and intensity of marking. 



Generally abundant amongst Leptospermum scoparium, on which the 

 larva doubtless feeds ; at Hamilton, Wellington, Christchurch, and Dunedin, 

 in August, September, January, and March. 



18. Hendecasticha, Meyr. 



Thorax smooth. Antennae in male ciliated, with an excavated notch 

 near base. Palpi moderate, porrected, second joint densely rough-haired 

 above and below. Forewings with strong costal fold in male. Hindwings 

 broader than forewings. Forewings with 11 separate veins (normal veins 

 7 and 8 probably coincident), 7 to costa. Hindwings with 7 veins (normal 

 veins 3 and 4 coincident), 4 approximated to 3 at base, 5 and 6 stalked. 



Nearly allied to Strepsiceros, but differing in only possessing 11 veins 

 in the forewings. The genus contains only the one New Zealand 

 species. 



35. Hend. cetJialiana, Meyr. 

 (Hendecasticha cethaliana, Meyr., Proc. Linn. Soc. N.S.W., 1881, 692.) 



Parva, alis ant. saturate fuscis, strigulis transversis albidis obsoletis ; 

 post, saturate fuscis.
