a transverse series of tolerably distinct elongate dark fuscous dots crossing wing from ¾ of costa to inner margin before anal angle, strongly angulated outwards in middle; veins posteriorly indistinctly marked with lines of whitish scales; a very fine dark grey hindmarginal line: cilia grey, indistinctly barred with whitish, and with extreme base whitish. Hindwings grey-whitish; cilia whitish, with a faint grey line.

Easily known from C. strigosus by the hook on the lower margin of the central streak, and the much narrower forewings.

Mr. R. W. Fereday took several specimens near Lake Wakatipu in January.

Male.—27–30 mm. Head, palpi, and thorax light greyish-ochreous, thorax sometimes mixed with blackish-fuscous; anterior margin of eyes very slenderly whitish; labial palpi moderately long, mixed with dark fuscous externally, beneath whitish at base. Antennæ fuscous-grey. Abdomen ochreous-whitish, apex more ochreous. Legs ochreous-grey-whitish, anterior and middle pair suffused above with dark fuscous. Forewings rather broad, considerably dilated posteriorly, costa gently arched, very faintly sinuate before middle, apex rounded, hindmargin oblique, strongly rounded; rather light brownish-grey, more brownish in disc, irregularly irrorated with black and white scales; veins posteriorly indistinctly lined with white scales; a short slender suffused blackish streak beneath costa at base; a straight thick longitudinal black streak beneath middle from base to middle of disc, much attenuated at base, lower edge suffused towards extremity; a short thick very oblique black streak in disc above extremity of basal streak, uniting with it to form a pointed hook; basal streak generally margined above by an ill-defined ochreous-white streak filling up the hook, sometimes suffusedly extending towards base almost to costa, sometimes almost obsolete; a very elongate-elliptical slender blackish ring in disc above middle, often partially obsolete; a blackish suffusion between branches of submedian vein at base; a strongly and regularly dentate outwards-curved slender blackish transverse line from ⅘ of costa to ⅘ of inner margin, sinuate beneath, posteriorly margined by a whitish suffusion; a row of distinct black dots on hindmargin: cilia whitish mixed with light grey, faintly barred. Hindwings grey-whitish, slightly suffused posteriorly with fuscous-grey; a cloudy grey line towards hindmargin below apex; hindmargin narrowly and suffusedly darker fuscous-grey; cilia grey-whitish.

A very distinct species, with the forewings broader than usual; allied to the preceding.
