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. comqrtus, 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. E. W. Fereday about 

 Porter's Pass and Mount Huttin January. 



2. Or. comqrtus, Butl. 

 (Hypochalcia corrupta, Butl., Proe. Zool. Soe. Lond., 1877, 399, PI. XLIIL, 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. Antennae 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 ; a 

 straight rather narrow central longitudinal white streak from base to hind- 

 margin, considerably 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 ; a dark fuscous 

 blotch on each margin of central streak about f, extending above to the 

 subcostal white streak, and beneath to the dorsal whitish suffusion ; a 

 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.
