Length. 3-4 mrn. 



Hab. Southern Bombay : Kanara. 



T. picea differs from T. melanura, Lefev. in its entirely piceous 

 colour and the nearly impunctate head, also in the absence of the 

 seneous gloss of the elytra ; T. puncticeps, Duviv. is narrower, the 

 head is rugosely punctured and the thorax of different shape and 

 sculpture.

xxxix, 1895, p. 283. 



Fulvous ; terminal joints of the antennae black ; elytra widened 

 at the middle, black, finely punctate-striate^-the apex nearly im- 

 punctate ; abdomen piceous. 



Of medially widened shape. Head fulvous, broad, nearly im- 

 punctate ; the clypeus with a fe\v very minute punctures, not 

 separated from the face, its anterior border emarginate at 

 the middle, its sides oblique with a distinctly raised margin ; 

 antenna? black, extending to the middle of the elytra, the 

 basal four joints fulvous, second and third joints nearly equal, 

 fourth and following joints elongate. Thorax more than twice as 

 broad as long, of equal width, the sides strongly rounded, the 

 posterior angles obsolete, the anterior margin not produced, the 

 surface reddish-fulvous, microscopically punctured. Scutellum 

 fulvous, broader than long, impunctate, its apex acute. Elytra 

 greenish-black, ovate, widened towards the middle, 1'ather opaque, 

 finely punctate-striate, the punctures nearly absent at the apex, 

 the shoulders produced into a narrow short ridge. Underside and

 less piceous. 



Length 3 mm.

The shape of this species is different from that of most of its allies, 

 being much more ovate in regard to the elytra, this and the nearly 

 impunctate head and thorax as well as the coloration will at once 

 distinguish the species. Taken during the rains. 



821. Tricliona ceylonensis, S p. n.

 apex of tibiae and the tarsi fulvous. 



Short and broad. Head finely and sparingly punctured, with a 

 short central groove ; eyes with a narrow sulcus above ; clypeus 

 separated from the face by a shallow transverse groove, finely 

 punctured ; antennse with the basal four joints fulvous, rest black, 

 third and fourth joints equal, following joints rather shorter and 

 distinctly thickened. Thorax twice as broad as long, sides rounded, 

 with narrow reflexed margins ; surface with very shallow punc-
