Genus AEMNESTUS, nov. 



Type, A. fulvitarsis^ Jac. 



Range. Assam. 



Body oblong, convex, subcvlindrical, glabrous. Eyes oblong ; 

 antennae filiform : mandibles of male very prominent and robust. 

 Thorax strongly transverse, anterior portion deflexed, sides 

 rounded. Scutellum transversely ovate. Elytra not wider at base 

 than the thorax, oblong, subcylindrical, lateral lobes not indicated. 

 Femora unarmed, tibiae entire, tarsi short ; claws appendiculate. 

 Prosternum distinctly longer than broad, widened anteriorly and 

 produced into a round cup-shaped projection, deeply hollowed 

 within ; anterior margin of the thoracic episternuin slightly 

 convex. 



Allied to Colatpoides, but distinguished by the shape of the 

 prosternum and the strongly developed mandibles of the male, 

 also by the different shape of the thorax. 



887. Aemnestus fulvitarsis, sp. n. 



Cupreous or greenish-aeneous ; antennae and tarsi fulvous ; body 

 beneath piceous. 



c? . Head closely rugose and punctured, a central short groove 

 at middle of vertex, three 

 smooth small spaces between 

 the eyes ; clypeus not sepa- 

 rated from the face, anterior 

 edge perfectly straight ; labrum 

 piceous; mandibles very prom-
