strong punctures^ the dise flavous, the margins metallic green ; 

 under side clothed with white silky pubescence, the breast blackish, 

 the abdomen fulvous as well as the legs, the femora at the middle 

 and the tibias at the apex greenish, tarsi comparatively short, the 

 first joint twice as long as the second one. 



The female is larger, the central green thoracic patch is also 

 much wider and of subquadrate shape, the elytra are entirely 

 metallic greenish or blue and the punctures are much finer; in ail 

 other respect there is no différence and I hâve no doubt about the 

 two forms being the sexes; the species is well distinguished by the 

 bisulcate thorax and the System of coloration. 



GYNANDROPHTHALMA SIKKIMIA sp. n. 



Below black, above pale falvous, the antennae (ihe basai joints

Elongate and subcylindrical, the head with a small central fovea, 

 impunctate, clypeus subtriangularly emarginate in front, antennse 

 extending to the base of the thorax, black, the lower three joints 

 flavous, eyes very large; thorax more than twice as broad as long, 

 the sides rounded, the posterior angles distinct, the surface impunc- 

 tate, with about five very obsolète fuscous spots, scutellura pointed 

 at the apex, elytra rather strongly lobed at the shoulders, rather 

 closely and finely punctured, below black, as well as the tarsi, legs 

 flavous. 



Hab. Sikkim (my collection). 



Allied to G. chrysomeloides Lac. but larger; the elytra not punc- 

 tate-striate and the tarsi black ; I possess two exactly similar spéci- 

 mens of this species.

 subopaque, scarcely perceptibly punctured, the shoulders with a 

 small black spot.
