Body, antennae and legs black, with the usual structure. Body convex. Head 

 and thorax scabrous, dull. Antennae stout, nearly filiform. Prothorax about four 

 times as broad as long. Sutures of the parapsides distinct. Abdomen smooth, shining, 

 subsessile, with cinereous tomentum towards the tip. Femora yellow at the tips, hind 

 femora minutely denticulate beneath. Tibiae yellow beneath, striped beneath with 

 black ; hind tibiae black at the base. Tarsi yellow, tips black. Wings cinereous ; 

 squamulae yellow; veins black; ulna about as long as the humerus. (Walker.) 



Mr Walker says : " Perhaps a variety of C. inclinator, a nati\e of Ceylon, Celebes 

 and Aru ; the black hue predominates a little more on the legs, and the wings are 

 cinereous, not pellucid. The Chinese specimens included with C. i7iclinator belong to 

 C. obscui-ator." 



H.\B. Hawaii (Koebele) ; Hilo (H. W. Henshaw), in July. 



This species was originally described from Hiogo, Japan. Specimens are also in 

 the U. S. National Museum taken by Koebele in Japan and China. In the Hawaiian 

 Islands Mr Koebele has bred it from a cocoanut Pyralid, Omiodes blackburni Butler.
