COLASPOSOMA. 453 



with very strongly rounded sides and a deeper transverse depres- 

 sion near the middle behind the anterior margin than is generally 

 found in other species. 



The male organ is strongly curved, terminating in an acute point 

 preceded by an elongate shallow cavity. 



790. Colasposoma andrewesi, Jac. Ann. Sue. Ent. Bely. xxxix, 1895, 



p. 272. 



Dark violaceous blue or cupreous ; basal joints of antenna and 

 the labrum fulvous. 



5 . Head finely aud moderately closely punctured, the punctures 

 well separated ; clypeus very obsoletely separated from the face ; 

 latter without tubercle or groove ; antennae with the basal six 

 joints fulvous, rest black or entirely fulvous, third and following 

 two joints equal, terminal joints elongate, scarcely widened. 

 Thorax twice as broad as long, sides rounded ; surface strongly, 

 closely and evenly punctured, but the intervals between the 

 punctures much wider than the punctures, sides rather more 

 closely punctate. Scutellum broader than long, distinctly punc- 

 tured. Elytra with some rows of strong punctures near the 

 suture only, rest of the disc occupied by two or three rows of 

 acute tubercles, extending but decreasing in number towards the 

 apex. Breast and legs metallic aeneous, abdomen dark ; femora 

 sometimes dark fulvous, unarmed. 



Length 4-5 mm. 



Hab. Burma: Paungde, Moulmein. 



Very closely allied to C. aspemtum, but differs in the much more 

 numerous elytral tubercles which in the present insect form several 

 rows. It is possible, however, that this form may be only a local 

 race. The male is unknown. 



Species ivith cupreous or purplish hands, glabrous above.

Var. obscurofusciatum, Jac. Ann. Soc. Ent. Bely. xxxix, 1895, p. 273. 



Beneath blackish, above aureo-cupreous ; margins of elytra and an 

 angulate longitudinal band on the disc of latter, blue or purplish. 



cf . Head very closely and rather strongly punctured, strigose 

 above the eyes ; clypeus punctured like the head ; antennae black, 

 basal joint metallic, third joint longer than the fourth, terminal 

 joint widened. Thorax twice as broad as long, sides round; 

 surface cupreous, punctured like the head, the margins more or 

 less purplish-blue. Scutellum subquadrate, with a few punctures. 

 Elytra very finely and irregularly punctured near the suture, more 

 strongly and less closely so at the sides, scarcely perceptibly 

 depressed below base. Breast and legs dark cupreous ; abdomen 

 nearly black. 



$ . Larger ; sides of elytra more strongly punctured, more dis- 

 tinctly depressed and with rugose interstices below the shoulders.
