about twice as long as second, the four apical segments laterally 

 compressed; eyes narrow and elongate ; apical segment of maxillary 

 palpi truncate and much smaller than the preceding. Prothorax 

 broader than long, front margin widely einarginate, sides straight, 

 on the upper surface there are no thickened convex areas along 

 the lateral margins. Elytra broader than prothorax, but hardly 

 so at the base, generally convex. Underside: the anterior end of 

 the metasternal process does not pass beyond the intercoxal space 

 of the middle legs; legs robust; anterior coxal cavities open; 

 inner edge of epipleuron of the elytra has, at least from the 

 middle, a row of fine cilia-like bristles. 

 Range : India, China, Tonkin.

Body oblong-ovate, convex. Colour generally metallic blue, 

 elytra and underside of abdominal segments (except the first) 

 light yellowish-brown to dark brownish-red ; in one case the 

 metallic blue colour is replaced by green. 



Head large, broad, and (viewed from the front) vertical in 

 position ; clypeus bounded on the upper side by a deeply impressed 

 curved line, from the middle of which runs a finely impressed 

 longitudinal median line, while there may be a shallow depression 

 on the area just at the top of the clypeus ; surface generally finely 

 and more or less sparsely punctate, round the eyes the punctures 

 become thicker, as well as on the clypeus ; eyes very narrow, 

 elongate and obliquely placed. Eirst segment of antennae very 

 stout and broad, second very small and rounded, third more than 

 twice as long as second and longer than fourth, fourth very 

 slightly longer than fifth, fifth and sixth almost equal to each
