Hel. illita, Feld. 

 (Atychia illita, Feld., pi. cxl., 32.) 



Male. — 21-24 mm. Head, palpi, antennae, thorax, abdomen, 

 and legs dark fuscous. Forewings elongate, posteriorly some- 

 what dilated, costa hardly arched, apex rounded-obtuse, hind- 

 margin hardly oblique, rounded beneath ; dark fuscous, irregu- 

 larly mixed with deep reddish, with some scattered whitish- 

 ochreous hair- scales ; two very obscurely indicated somewhat 

 darker spots in disc, first oblique-transverse, before middle, 

 second sub-oblong, beyond middle ; between these are a few 

 scattered white scales ; a white irroration forming an obscure 

 transverse streak from £ of costa to anal angle ; four very small 

 blackish-fuscous subquadrate costal spots between middle and 

 apex, separated by ochreous-white spots : cilia fuscous, basal 

 half darker and mixed with deep reddish, tips mixed with 

 ochreous- whitish. Hindwings bright orange ; a broad irregular 

 blackish hindmarginal border, dilated at apex, and extended as 

 a narrow attenuated streak along costa to base ; inner margin 

 suffused with blackish ; a more or less defined irregular black 

 streak from base to hindmarginal band beneath middle, some- 

 times reduced to a partial irroration : cilia orange, tips paler, 

 base generally blackish on upper half of hindmargin. 



Var. a. Thorax and forewings almost wholly suffused with 

 bright ferruginous, all markings absent. 



Nelson and Dunediu, in January ; flies actively in the sun- 

 shine over the tops of high Leptospermum bushes ; seems local, 

 but common where it occurs. 



Hel. atychioides, Butl. 



(Tachyptilia atychioides, Butl., Proc. Zool. Soc. Lond., 1877, 405, 

 pi. xliii., 14.) 



Male, female. — 13-16 mm. Head, palpi, and thorax dark 

 fuscous, mixed with brownish-ochreous. Antennae and abdo- 

 men dark fuscous. Legs dark fuscous, ringed with whitish. 

 Forewings elongate, posteriorly somewhat dilated, costa hardly 

 arched, apex obtuse, hindmargin nearly straight, somewhat 

 oblique, rounded beneath ; dark fuscous, thickly strewn with 

 brownish-ochreous hair-scales ; the partial obsolescence of these 

 tends to form a streak along inner margin, an irregular trans- 

 verse spot in disc before middle, a small round spot beyond 

 middle, and an irregular narrow somewhat angulated fascia 

 from § of costa to f of inner margin ; sometimes the disc is 

 suffused with whitish except on these markings ; and the 

 fascia is margined posteriorly by a narrow whitish fascia ; all 

 these markings sometimes not traceable : cilia fuscous, base 

 darker, tips whitish on a short space beneath apex. Hindwings 

 dark fuscous, more or less distinctly lighter towards base (less in
