trifida:. 287 



line pale yellow-brown, rather direct and complete, edged 

 inwardly by a narrow, well-defined, dull brown stripe, and 

 outwardly by a more indistinct umbreous cloud lying along 

 the hind margin ; orbicular and reniform stigmata visible, 

 dull brown, faintly edged by a line paler than the ground 

 colour ; from the reniform arises a curved dull brown stripe 

 which attains the dorsal margin and partially represents the 

 central shade ; cilia pale umbreous, dashed with darker. 

 Hind wings uniformly dull smoky-white or pale smoky- 

 brown ; cilia similar. Female very slightly smaller ; fore 

 wings more rounded at the apes, abdomen a little stouter and 

 with a smaller anal tuft, otherwise closely similar. 



Underside of the fore wings smoky -brown along the costa, 

 shading off to smoky-white along the dorsal margin ; reniform 

 stigma visible, dusky black ; beyond it the smoky shading- 

 is abruptly cut off, leaving a paler band before the hind 

 margin. Hind wings dusky white, dusted with red-brown 

 along the costal region, and clouded with smoky-brown along 

 the hind margin, which is edged by a darker brown line ; 

 central spot minute, smoky-black ; body whitish-brown ; legs 

 dull brown. 



Hardly variable except in a small degree in the depth of 

 the ground colour and markings of the fore wings. 



This species is constantly confounded with the next 

 (C. blanda), but may be separated by its coarser texture 

 and rather broader fore wings, and the absence of the 

 smoothed-down silky gloss so noticeable in that species and 

 in C. ambigua ; the central shade on the fore wings is also, 

 usually, more conspicuous. 



On the wing in July and August. 



Larva. Head dusky yellow-brown; general colour pale 

 reddish-drab or buff ; back more or less tinged with purplish- 

 brown ; dorsal line whitish, bordered with black at the 

 middle of every segment ; subdorsal lines yellowish-white, 

 edged on the upper side narrowly, and on the lower side
