Meyrick. — Notes on New Zealand Pyralidina. 67 



Xeroscopa, Meyr. 

 Xer. astragalota, Meyr. 

 Also from Mount Arthur (4,000 feet). 



Xer. niphospora, Meyr. 

 Also from Mount Arthur (4,000 to 4,500 feet). 



Xer. nomeutis, Meyr. 

 Also from Mount Arthur (4,000 feet). 



CRAMBIDJE. 



Orocrambus, Meyr. 



I have explained elsewhere that, as in some individuals of 

 0. melampetrus, vein 8 of the hindwings is free, whilst in others 

 it anastomoses with vein 7 in the usual way, this character 

 cannot he used to define the genus ; but that the genus is, not- 

 withstanding, good and tenable if the distinction from Crambus is 

 made to consist in the densely hairy uudersurface of the thorax 

 and coxae. As thus defined, the genus will include O. melam- 

 petrus, Meyr.; O. catacaustus, Meyr., O. tritonellus, Meyr. (the 

 two latter having been formerly placed in Crambus), and the 

 following new species. 



Or. mijlites, n. sp. 



Male, female. — 23-25 mm. Head whitish-ochreous, fuscous 

 on sides. Palpi 3^, whitish-ochreous, apex mixed with blackish. 

 Antennae dark fuscous, ciliations in male J. Thorax ochreous- 

 fuscous, shoulders and a suffused longitudinal dorsal streak 

 ochreous-wbitish. Abdomen grey, posteriorly irrorated with 

 ochreous-whitish, anal tuft mixed with yellow-ochreous. Legs 

 dark grey, suffusedly irrorated with whitish-ochreous. Fore- 

 wings elongate, posteriorly gradually dilated, costa hardly 

 arched, apex obtuse, hindmargin obliquely rounded ; bronzy- 

 fuscous, more or less ochreous-tinged ; a moderate straight white 

 central longitudinal streak, irregularly irrorated with fuscous- 

 grey, from base to hindmargin, margined above with dark fus- 

 cous from before middle to near hindmargin, and beneath by a 

 dark fuscous attenuated streak from near base which diverges in 

 middle and runs to hindmargin above anal angle, often accom- 

 panied at divergence by a few white scales ; a white irroration 

 towards costa about f ; a narrow white irroration along inner 

 margin from base to anal angle, towards base margined above 

 with dark fuscous : cilia glossy light grey. Hindwings grey ; 

 hindmargin suffusedly darker ; cilia light grey, tips whitish. 



Mount Arthur (4,000 to 4,800 feet), in January ; common, 

 frequenting swampy places. Nearest to O. catacaustus, but 

 easily distinguishable by the whitish dorsal streak of thorax, 

 and the grey irroration of the white median streak of forewings.
