oblique, twice sinuate, anteriorly dark-margined ; a thin dark line parallel 

 to second line, sometimes obsolete ; subterminal broad, waved, parallel to 

 termen : cilia vellowish-white, barred with fuscous, and with a fuscous 

 basal line. Hindwings rather narrow ; brownish-fuscous, densely sprinkled 

 with grey-whitish on basal § ; two parallel curved white fasciae beyond 

 middle, second sometimes obsolete : cilia as in forewings. Undersides 

 ochreous-brown ; second and subterminal lines of forewings and post- 

 median lines of hindwings usually indicated ; a dark discal spot on both 

 wings. 



$. 16 mm. Semiapterous. Forewings oblong, apex subacute, termen 

 hardly rounded, oblique. Hindwings oblong, slightly narrower than fore- 

 wings, termen and dorsum slightly concave. Legs and antennae normally 

 developed. Palpi small and not densely haired. Legs fuscous, tarsal joints 

 annulated with white. The rest of the insect is white minutely speckled 

 with dark fuscous, and with a slight ochreous tint on head and anterior 

 portion of thorax. 



In this species the antennal pectinations reach their highest develop- 

 ment, and it is significant that this is coincident with the semiapterous 

 condition of the female. It is probable that N. villosa is an offshoot from 

 N. orphnaea (Meyr.), that species being attached to rocky and shingly ground, 

 while the former has become adapted to areas covered with more ample 

 vegetation. 



Common from December to February in well-grassed situations at from 

 3,000 ft. to 4,000 ft. The male was first met with on The Hump (Waiau) 

 in 1910, and was subsequently found on the Hunter Mountains. The 

 female was not discovered till December, 1915, when three specimens were 

 taken by Mr. C. C. Fenwick on The Hump. So far, the two localities 

 mentioned are the only ones in which the species has been observed, but 

 in all probability it also occurs on the intervening Princess Range. 



Crambidae. 

 Orocrambus cultus n. sp. 



cJ?. 24-26 mm. Head, palpi, and thorax dark ochreous-brown, in $ 

 lighter. Abdomen ochreous-grey -brown. Forewings elongate, costa slightly 

 arched at base, thence almost straight, apex rectangular, termen bowed, not 

 oblique ; brownish-ochreous, finely sprinkled with black and, in $, with 

 grey ; a rather broad central ochreous-white streak from base to f , mar- 

 gined with blackish beneath and round apex ; a suffused and interrupted 

 whitish transverse fascia at § ; second line prominent, white, shortly oblique 

 towards termen, thence straight to before tornus, margined anteriorly with a 

 series of black dashes : cilia fuscous-grey, tips and a series of obscure basal 

 dots white. Hindwings fuscous-grey, in $ slightly cchreous-tinged : cilia 

 grey-whitish with a fuscous median line. 



Not far removed from O. machaeristis Meyr., but differing in the pre- 

 sence of the well-defined second line ; the basal streak is also much shorter. 



Discovered by Mr. M. O. Pascoe on Cecil Peak, Wakatipu, at an altitude 

 of about 6,000 ft. The examples (two of each sex) were secured early in 

 January and on the 25th February. Types in coll. M. O. Pascoe. 



Crambus scutatus n. sp. 



cJ. 29-32 mm. Head and palpi ochreous-brown. Thorax brown with 

 broad suffused ochreous-whitish central stripe. Abdomen greyish-ochreous. 

 Forewings moderate, somewhat oblong, costa rather strongly and evenly
