fuscous, angulated near costa, on costa blackish ; orbicular and reniform 

 finely outlined with black, orbicular rather large, suboval, oblique, reniform 

 large, transverse-oval, pale whitish-rosy ; a broad irregular dark-fuscous 

 streak above fold from base to termen, including a strong black line along 

 fold, edged beneath by an irregular streak of white suffusion from before 

 middle to subterminal line, on which it is bent upwards for a short distance ; 

 subterminal line otherwise faintly indicated, pale, waved, traversing an 

 oblique dark reddish-fuscous suffused streak above middle : cilia pale ochre- 

 ous, suffused with greenish and barred with fuscous. Hindwings rather 

 dark grey, tinged with pinkish, with suffused darker grey discal spot and 

 terminal band : cilia light greyish-ochreous, with a greenish-fuscous shade. 



A distinct species. 



I have been asked to express an opinion on the classification adopted 

 by Sir George Hampson in his " British Museum Catalogue " for this family, 

 so far as it relates to New Zealand species. The matter cannot be discussed 

 in detail without entering on a general survey of other famias ; but, speaking 

 generally, I may say that I tee no reason at present to alter my previous 

 views as to the limits and constitution of the New Zealand genera. I 

 should not recommend any student of the group to adopt the generic divi- 

 sions employed by Sir George Hampson imless he finds that he can in 

 practice always clearly distinguish these genera by the structural characters 

 employed, and also finds that these genera appear to him truly natural — 

 that is, such that the species in each genus are more closely allied together 

 through inheritance of common characters than they are to the species of 

 any other genus. I do not myself find this, and am therefore at present 

 unable to adopt his classification, which appears to me to conflict with, 

 geographical distribution, instead of explaining it. 



Crambid^. 

 Craxnbus thrincodes, n. sp. 



cf . 28 mm. Head white, with a light ochreous spot behind eye. Labial 

 palpi fuscous, basal joint white. Maxillary palpi white, towards base dark 

 fuscous. Antennae white, beneath brownish-ochreous. Thorax white, pa- 

 tagia suffused with pale ochreous and sprinkled with dark fuscous. Ab- 

 domen whitish-ochreous tinged with yellow. Forewings elongate, very 

 narrow, gradually dilated, costa slightly arched, apex obtuse, termen slightly 

 rounded, oblique ; light ochreous-broAmish, veins sprinkled with dark 

 fuscous ; a broad white costal streak, suffused beneath, enclosing a narrow 

 blackish costal streak from base almost to apex, which is divided into three 

 portions by rather broad interruptions of white before middle and at f 

 (representing origin of first and second lines) ; on lower margin of the white 

 streak are a longitudinal projection at base, and an inwards-oblique pro- 

 jection representing first line, space between and beyond these to near 

 middle suffused with blackish ; beyond this a suffused white streak in disc 

 to I, between which and costal streak is enclosed a round white discal spot 

 at f edged with dark fuscous and centred with a fuscous dot ; second line 

 from costal streak to dorsum before tornus white, sharply dentate, indented 

 near dorsum : cilia light brownish, partially barred with white. Hind- 

 wdngs whitish-ochreous ; a small spot of grey suffusion on costa before 

 apex ; cilia ochreous- whitish.
