Range. Northern India to Borneo. 



S . Head short, almost vertically deflexed in front ; mandibles 

 short, abruptly incurved and acute at tip, crossing one another 

 when closed ; labrum very short and broad ; eyes large and pro- 

 minent, emarginate in front ; upper lobes not widely separated 

 from each other, lower lobes closely approximated" to base of 

 mandibles in front. Antenna? a little longer or shorter than the 

 body ; first joint short, obconical ; third to tenth strongly com- 

 pressed, longitudinally carinated, produced into a sharp angle or 

 tooth at the apex on the posterior side ; third twice as long as the 

 first, broader, but scarcely longer, than the fourth ; fifth to tenth 

 successively shorter and narrower. Prothorax transverse, with 

 distinct lateral edge placed at some distance from the outer angle 

 of the acetabulum and produced into an acute spine in the middle : 

 each flank with a closely punctured area, sometimes completely 

 circumscribed by a raised margin, lying between the prosternal 

 suture and the anterior half of the lateral edge. Elytra broader 

 than the prothorax, twice or more than twice as long as broad, 

 rounded and unarmed at the apex; each with three distinctly 

 raised costae. Legs moderately long, laterally compressed ; first 

 joint of hind tarsus a little longer than the second and third 

 united. Prosternum strongly arched between the coxae, slightly 

 projecting beyond them posteriorly. Last ventral segment slightly 

 sinuate at the apex. 



$ . Antennae shorter and much narrower than those of the 

 male, the third and fourth joints scarcely broader than the fifth 

 and following joints : the third nearly half as long again as the
