138 Transactions. — Zoology. 



straight white central streak from base to hindmargin somewhat above 

 middle, lower edge rather irregular, narrowed towards base ; inner margin 

 very slenderly white towards base ; a narrow white streak along hindmargin 

 from extremity of central streak to apex : cilia pale shining grey, on upper 

 half of hindmargin barred with white. Hindwings whitish-grey ; cilia white. 



Closely allied to C. vittelhis, with which it agrees in the distinctly barred 

 cilia of forewings, and resembling the most simply marked forms of that 

 species, but constant ; larger, more ochreous-yellowish, not fuscous ; the 

 antennae of male somewhat more slender, the apex of forewings less pointed 

 and the hindmargin not distinctly sinuate, the hindmarginal black dots 

 absent, and the hindwings greyer, not ochreous-tinged. 



Lake Wakatipu, on the dry mountain sides at from 2,000 to 5,000 feet ; 

 taken commonly in December. 



29. Cr. sophronellus, n. sp. 



Female. — 19 mm. Head and thorax ochreous-white, coarsely irrorated 

 with greyish-fuscous. Palpi long, whitish, externally irrorated with grey. 

 Antennae grey. Abdomen whitish, irrorated with grey. Legs grey-whitish. 

 Forewings elongate, tolerably oblong, costa hardly arched, apex round- 

 pointed, hindmargin straight, rather strongly oblique ; greyish-fuscous, 

 densely irrorated with white, and with a few black scales : cilia whitish- 

 grey mixed with white, base white. Hindwings light fuscous-grey, towards 

 hindmargin darker ; cilia grey- whitish. 



Nearly allied to C. cyclojricas, but shorter-winged, and immediately 

 separated from it by the grey hindwings ; possibly other specimens may 

 possess distinct markings, since in the female of C. cyclopicus they are also 

 sometimes quite obsolete. 



One specimen received from Mr. E. W. Fereday, of uncertain locality. 

 30. Cr. oncobolus, n. sp. 



Male, female. — 24-27 mm. Head white. Palpi very long, white, 

 externally slightly ochreous-tinged. Antennas whitish, in male shortly 

 ciliated. Thorax white or greyish-white, shoulders ochreous. Abdomen 

 whitish-ochreous. Legs white, anterior pair internally fuscous. Forewings 

 elongate, narrow, tolerably dilated, costa gently arched, apex round-pointed, 

 hindmargin straight, oblique, strongly rounded beneath ; pale fuscous ; all 

 veins suffused with white, more or less confluent towards costa posteriorly, 

 and obscurely margined with dark fuscous ; a narrow white central streak 

 from base to middle of disc, its apex sharply hooked downwards, margined 

 beneath throughout by a strong black streak finely attenuated at base, and 

 its apex margined posteriorly with black ; above the white central streak is 

 a yellow-ochreous streak becoming dilated beyond it and suffused into ground- 

 colour, and beneath the black streak a yellow-ochreous streak reaching apex
