COLASPOSOMA. 447 



aeneous, obscure fulvous beneath, the rest black, terminal joints 

 widened. Thorax more than twice as broad as long, sides rounded; 

 surface extremely closely and slightly more strongly punctured 

 than the head, punctures confluent and the interstices rugose at 

 the sides ; an obsolete short depression near the middle at sides. 

 Scutellum subquadrate, punctured. Elytra not more strongly 

 punctured than the thorax, punctures arranged in rows on the 

 inner disc ; base with shallow transverse depression below the 

 shoulders, the depression more strongly punctured with trans- 

 versely rugose interstices ; extreme lateral margins metallic green. 

 Body beneath and legs greenish, tibiae obscure cupreous. Pro- 

 sternum closely pubescent. 



5 . Elytra with strong transverse rugosities at the sides, which 

 extend to the apex. 



Length 4|-5 mm.

c? . Entirely dark blue. Head closely subrugose-punctate, 

 sides strigose, middle with a small fovea, a small tubercle at base 

 of clypeus ; antennae black, not extending to middle of elytra, 

 terminal five joints strongly dilated and compressed, basal joints 

 dark blue. Thorax more than twice as broad as long, sides rounded, 

 anterior angles acutely produced ; disc closely and rather strongly 

 punctured, obsoletely transversely depressed near the anterior 

 margin, basal portion transversely convex. Scutellum sub- 

 quadrate, smooth or with a few punctures. Elytra subquadrately 

 oblong, wider at the base than the thorax, very obsoletely de- 

 pressed below the base, punctured like the thorax, puncturation 

 arranged behind the middle in very close irregular lines ; anterior 

 tibiae strongly widened and curved at base. Male organ short 

 and curved, upper surface with a deep ovate cavity near apex, the 

 latter obtusely but narrowly pointed. 



$ . Elytra' strongly rugose at the sides, two short obsolete 

 costae near the lateral margins below shoulders ; puncturation at 

 sides of thorax very close, that on the elytra more regularly 

 arranged in rows on the inner disc. 



Length 7-8 mm. 



Hob. Southern Bombay ; Ceylon ; Assam ; Burma ; China. 



Principally distinguished by its entirely dark blue or violaceous 

 colour, large size (though I have not seen specimens 10 mm. in 

 length that Baly speaks of), and close and uniform puncturation. 

 Baly's description refers to the female only. The terminal 

 joints of the antennae are more than usually dilated in this 

 species.
