44 Transactions. — Zoology. 



Male, 10i-12 mm. ; female, 14 mm. — Head and thorax in male deep 

 brownish-ockreous, in female reddish-ochreous. Forewings narrow, costa 

 moderately arched, hindmargin almost straight, rather strongly oblique ; 

 in male deep brownish-ochreous, mixed with dark fuscous, especially pos- 

 teriorly, in female reddish-ochreous, with a few dark fuscous scales; a 

 tolerably distinct dark fuscous dot in disc beyond middle : cilia ochreous, 

 towards anal angle in male greyish, in female whitish. Hindwings and 

 cilia in male blackish, in female whitish. 



Markedly distinct by its unicolorous forewings, and the strongly-con- 

 trasted hindwings. 



Taken in plenty in January amongst long grass near Hamilton, on the 

 skirts of the forest. This, as well as the other species, appears to be very 



local. 



6. Hakmologa, n. g. 



Thorax smooth or rarely crested. Antennae in male ciliated. Palpi 

 moderate or rather long, porrected, second joint triangularly scaled. Fore- 

 wings in male with strong costal fold. Hindwings broader than forewings. 

 Forewings with 12 veins, 7 and 8 separate, 7 to hindmargin. Hindwings 

 with 8 veins, 3 and 4 separate at origin, 5 approximated at base to 4, 6 and 

 7 stalked or separate. 



Separated from Proselena by the costal fold, from Cacoecia by the separa- 

 tion of veins 3 and 4 of hindwings. To this genus belong some of the 

 species formerly referred provisionally to Cacoecia ; I have at present five 

 New Zealand species, but have not observed the genus as occurring else- 

 where. These species, which are very various in superficial appearance, 

 may be separated as follows : — 



A. Forewings whitish in ground-colour. 



1. Hindwings ochreous-whitish U. amplexana. 



2 grey . . . . • • • • • • • • . . 10. sisyrana. 



B. Forewings fuscous or grey. 



1. Hindwings ferruginous-yellow or whitish -yellow 13. anea. 



2. „ grey. 



a. Forewings with a whitish hind-marginal blotch 12. zatrophana. 



b. „ without whitish blotch 11. oblong ana. 



10. Harm, sisyrana, n. sp. 



Media, alis ant. dilute griseis, nigro-strigulatis, area basali obscura, 

 fascia media obliqua, maculisque costse posterioribus quatuor parvis 

 saturatioribus ; post, griseis. 



Male, 17i mm; female, 20 mm.— Head, palpi, and thorax grey-whitish, 

 mixed with fuscous-grey and blackish ; palpi rather short ; thorax crested. 

 Antenna? grey. Abdomen whitish-grey. Legs grey-whitish, anterior and 

 middle tibia; and all tarsi suffusedly banded with dark fuscous. Forewings
