quite touching hindmargiu ; above this are sometimes one or two very 

 short blackish-fuscous lines on veins; generally a hindmarginal row of cloudy 

 blackish dots : cilia ochreous- whitish, mixed with white, with two pale grey 

 lines. Hindwings H, in male grey-whitish, with a grey luuule ; in female 

 whitish-grey, becoming darker grey posteriorly, with a darker lunule ; cilia 

 white, in female with a grey line. 



Conspicuously characterized by the sharply-defined interrupted blackish 

 streak from base to apex. 



Christchurch and Lake Wakatipu, on dry grassy hill-slopes, in Decem- 

 ber, February and March ; tolerably common. 



* 3. Tetraprosopus, Butl. 



Forehead vertical. Ocelli present. Tongue well- developed. Antennae 

 moderate, f of forewings, in male filiform, hardly perceptibly ciliated (^). 

 Labial palpi rather long, straight, porrected, second joint beneath with 

 dense projecting tuft, terminal joint moderately long, exposed. Maxillary 

 palpi rather long, triangularly dilated. Posterior tibiae with outer spurs 

 half inner. Abdomen moderate. Forewings with vein 11 rather oblique. 

 Hindwings almost twice as broad as forewings ; 3 remote from 4, 4 and 5 

 stalked ; lower median naked ; discal area above it furnished with long 

 hairs, continued almost to hindmargin ; internal area loosely haired. 



Differs from Xeroscopa only by the approximate obsolescence of the 

 antennal ciliations. But the extension of the discal hairs of the hind- 

 wings almost to the hindmargin is only found also in A'. pliilonephes, of 

 which the male is unknown, and it is possible that that species should be 

 referred to this genus, in which case there would be an additional point of 

 distinction. 



Butler's characters for this genus do not suffice to separate it from 

 Scoparia. 



* 60. Tetr. meyrickii, Butl. 

 (Tetraprosopus meyrickii, Butl., Ann. Mag. Nat. Hist., 1882, 97.) 



Male, female. — 24-25 mm. Head and thorax greyish-fuscous, or reddish- 

 ochreous-brown, often mixed with whitish, sometimes with a blackish- 

 fuscous lateral stripe from eye to extremity of patagia. Palpi 2£, dark 

 fuscous, mixed with white above, basal joint white. Antennae dark fuscous. 

 Abdomen light ochreous-grey. Legs whitish, anterior and middle pair 

 suffused with dark fuscous. Forewings elongate-oblong, narrow, hardly 

 dilated, narrow, costa almost straight, apex obtuse, hindmargin straight, 

 rather oblique ; greyish-fuscous or ochreous-fuscous, irrorated irregularly 

 with whitish and darker fuscous ; first hue very obsoletely indicated, 

 strongly angulated above middle ; sometimes an irregular blackish streak 

 from base along submedian fold to first line, often obsolete ; a dark fuscous
