p. 142. 



Colasposoma capitatum, Jctc. Ann. Mus. Civ. Genova, xxvii, 1889, 

 p. 178. 



Bronze, metallic blue or green. 



J . Head closely and strongly punctured, strigose above tbe 

 eyes between which there is a small tubercle : clypeus transverse, 

 closely punctured; labrum, mandibles and base of palpi nearly 

 black ; antennae piceous, basal joints bluish, apex of eacb fulvous, 

 second to fourth joints gradually elongate, terminal five widened. 

 Thorax twice as broad as long, sides rounded, angles dentiform but 

 not produced, disc convex, closely and finely punctured at the 

 sides, more remotely so in the middle. Scutellum broad, sparingly 

 punctured. Elytra wider at base than the thorax, with a very 

 feeble depression below the shoulders, not more strongly punc- 

 tured than the thorax ; punctures arranged in irregular rows near 

 the suture, distinct to apex ; sides below shoulders more strongly 

 punctured within the depression and with slightly rugose inter- 

 stices. Body beneath and legs aeneous, finely pubescent. Pro- 

 sternum broad, subquadrate. Anterior tibiae widened at the apex, 

 slightly curved ; first joint of tarsi dilated. Generative organ 

 moderately curved, rather suddenly contracted near the apex, the 

 latter terminating broadly and rounded not pointed. 



2 . Elytral interstices at the sides strongly transversely rugose 

 and partially tuberculate, a single longitudinal costa near the 

 lateral margins, the rugosities not extending to the apex. 



Length 67 mm. 



Hab. India : Southern Bombay ; Burma : Bhamo ; Andaman 

 Islands ; Penang. 



A very variable species and difficult to define accurately. 

 Clark's type was described from Penang with the underside and 

 legs as black, which is not the case, as the type in the British 

 Museum proves. These parts are bronze-coloured like the upper- 

 side. All the specimens from the other localities given above are 

 so closely allied in sculpture that it is impossible to separate them. 

 The male was unknown to Clark. 



C. capitatum, Jac., on re^-examination, does not seem to differ 

 sufficiently to justify its separation. 



780. Colasposoma subopacum, sp. n. 



Dark aeneous or blue, moderately metallic; labrum, antennae 

 and tarsi black. 



c? . Oblong. Head deeply rugosely punctured, strongly strigose 

 above the eyes ; a distinct tubercle at base of clypeus, the latter 

 extremely closely rugose-punctate, angulate-emarginate in front, 

 sides obliquely truncate ; antennae with the basal four joints
