 antennae and thorax testaceous, elj^tra nu>tallic dark green, clo- 

 sely riigose-panctate, tihiae and tarsi black, claws bitid.

 the first joint of the posterior tarsi as long as the following three

Hab. Si-Rambé. 



Differing in the structure of the clypeus and (//. metaUka, .Tac. 

 excepted) in the metallic green and rugose elytra ; their epi-

 other differences of importance are not present. 



Sosilbiella, gen. n. 



Body elongate, antennae filiform , the second and third joint

 claws appendiculate, anterior coxal cavities open. 



This genus will have to be placed near Haplosomuides, Duviv. 

 from which it differs in the swollen head, the shorter third joint 

 of the antennae and in the transverse thorax.
