Ilab. Sikkim ; Khasia Hills. 



Expanse, 6 & $ , 41-44 mm. 



This species is local, but not uncommon where it occurs ; it may be readily distin- 

 guished from its neighbours by its brighter colour, larger size, and the clear, clean-looking 

 ochre-brown of the under surface. The genitalia have the tegumen excavated and open 

 at the apex, and the hooks, jointed at the elbow, are from that point long and slender ; 

 the clasps are very deep, excavated at the tips, forming a sort of jaw, the upper part of 

 which is resolved into a long, curved, sharp hook. The penis is long and slender.

Hab. Himalayas; Burma; China; Sikkim.

Herr Rober has described his violacea, from " the East Indies," as a distinct species, 

 but it agrees in every respect with this insect — there is not one small point in which 1 

 can differentiate it. It may be known from cenea Hew, by the broadish outer margins, 

 by the pale colour of the underside, by the tail being little more than a long tooth, 

 and by the absence of an anal black spot and any metallic scaling. 



The exceedingly broad dark margins of the secondaries are also a marked charac- 

 teristic of the species. The genitalia are not unlike those of oenea Hew., but the 

 tegunien-hooks are short and not elbowed ; the clasps are broader, with the upper 

 part of the jaw pointed but broader. The penis is decidedly stouter.
