 short wings, easily recognized by the very broad brownish- 

 black border of the rosy-red hind wing and the olive-yellow 

 stigma of fore wing. Head, thorax and abdomen brown, with- 

 out the pale interantennal bar -of C. r. rubricosa. Fore wing

 ochreous, crossed by a purplish-grey longitudinal stripe ; apex 

 olive-green without the oblique apical line of C. r. rubricosa. 

 Hind wing bright pink, the outer half deep broAvn, with a line 

 near anal angle. Underside paler. Expanse : 100 mm. 



<$. Tenth tergite smooth, rounded at end, which is turned 

 downwards, longitudinally grooved ; ninth tergite (proximal 

 part of the supra-anal process) not hairy ; tenth sternite 

 mesially produced into a triangular, apically rounded lobe. 

 Clasper (fig. 60 A) obliquely rounded at apex, this apical lobe 

 smaller than the harpe, which is concave, spoon-shaped, with 

 the apex produced into a pointed hook directed dorsad ; 

 dorsal edge of clasper widened internad near end of harpe and 

 densely beset with stiff hairs ; the dense tuft of hair-scales near 

 apex of harpe about twice as long as the clasper is broad 

 before the end. Penis -sheath dor sally longer than ventrally, 

 obliquely truncate, without external armature ; within the
