COLASPOSOM A. 
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 41-5 mm.

d ■ 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 live 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 
tibise 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. 
5 . Elytra strongly rugose at the sides, two short obsolete 
costre 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. 
Hah. 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.
