whitish, becoming gradually more ochreous towards base ; inner marginal 
edge sometimes very narrowly ochreous-whitish ; a straight moderately 
broad central longitudinal ochreous-white streak from base to hindmargin, 
attenuated on basal third and before hindmargin, more or less distinctly 
margined with dark fuscous: cilia pale whitish-ochreous, on basal third light 
grey, with a distinct ochreous-white spot on central streak. Hindwings dark 
fuscous ; cilia ochreous-white or whitish-ochreous, with a grey basal line. 
Easily distinguished from all the other New Zealand species by the 
nearly uniform dark fuscous hindwings with whitish-ochreous cilia. In 
form and general characteristics it is closely allied to C. corruptus, but 
differs widely in the deep ochreous-brown colouring, and the absence of the 
dark fuscous blotches. These two species are shorter-winged, more stoutly 
built, and more densely scaled than usual, but the venation is typical. 
A mountain species; taken commonly by Mr. R. W. Fereday about 
Porter’s Pass and Mount Hutt in January. 
2. Cr. corruptus, Butl. 
(Hypochaleia corrupta, Butl., Proc. Zool. Soc. Lond., 1877, 399, Pl. XLII., 9.) 
Male.—18-19 mm. Head dark fuscous, face and back of crown 
ochreous-whitish. Palpi moderate, dark fuscous mixed with greyish- 
ochreous, beneath whitish towards base. Antenne dark fuscous. Thorax 
dark fuscous, sides more ochreous-fuscous, shoulders with a few ochreous- 
whitish scales. Abdomen dark fuscous, suffused with pale greyish-ochreous 
posteriorly. Legs whitish-ochreous, anterior and middle pair suffused with 
greyish-fuscous. Forewing short, moderately broad, costa almost straight, 
slightly sinuate in middle, apex almost acute, hindmargin very slightly 
rounded, rather strongly oblique; ochreous-brown; extreme costal edge 
suffusedly ochreous-whitish, towards base and apex dark fuscous; a slender 
very ill-defined white streak beneath costa from middle to apex; inner 
margin rather narrowly suffused with dull ochreous-grey-whitish, towards 
base very narrowly and margined above by a short dark fuscous streak ; 8 
straight rather narrow central longitudinal white streak from base to hind- 
margin, eonsiderably attenuated towards both ends, lower edge indented 
beyond middle; a broad dark fuscous streak along each margin of central 
streak from near base to middle, attenuated anteriorly; & dark fuscous 
blotch on each margin of central streak about 3, extending above to the 
subcostal white streak, and beneath to the dorsal whitish suffusion ; @ 
rather narrow dark fuscous band along hindmargin, interrupted by central 
streak, dilated towards costa: cilia grey, tips paler, with a rather darker 
grey basal line, on upper half of hindmargin more or less scaled with 
ochreous-white. Hindwings fuscous-grey, with a narrow dark fuscous 
hindmarginal band ; cilia grey-whitish, with a grey basal line.
