Head feebly depressed, distinctly wider in front that at vertex; 

 front not narrowed by the insertion of the antennae, and sometimes 

 longitudinally grooved; epistoma short and emarginate in front: 

 antennal cavities small, rounded, margined posteriorly by an ele- 

 vated carina, and situated near the inner margin of the eyes. xVn- 

 tennae short; first joint elongate, and strongly clavate; second very 

 short and globular; third elongate, shorter than the first, subcylin- 

 drical, and feebly exp'anded at apex; following joints triangular, 

 wider than long, robust, strongly dentate on the inner side, and 

 the serrate joints armed with poriferous pores and foveae on both 

 sides of the joints. Eyes large, strongly convex, broadly oblong, 

 and much closer to each other on the vertex than on the front. Pro- 

 notum wider than long, attenuate anteriorly; disk feebly convex, 

 and not longitudinally sulc'ate. Scutellum small, transverse or sub- 

 rotundate. Elytra nearly truncate at base, strongly attenuate pos- 

 teriorly, with the sides near apex strongly serrate. Sternal cavity 

 formed by the mesosterum and metasternum; mesosternum divided, 

 the lateral branches long 'and oblique; metasternum truncate in 

 front, with a shallow arcuate emargination in front, and a narrow 

 longitudinal groove on the disk at middle. Prosternum wide, feebly 

 convex, anterior margin truncate, margined, and declivous near the 

 eyes; prostorn'al process wide and not sulcate at middle. Posterior 

 coxae dilated internally; anterior margin strongly sinuate, and the 

 posterior margin straight. Legs slightly robust; anterior 'and me- 

 dian femora swollen at middle, the posterior pair subcylindrical and 

 feebly flattened on both sides; tibiae slender, cylindrical, feebly en- 

 larged at the apex, the anterior and middle pairs feebly arcuate, the 

 former longitudinally carinate on the outer surface. Tarsi depressed, 

 gradually triangularly enlarged, and flattened from the first to 

 fourth joint; first joint of posterior pair nearly as long as the fol- 

 lowing two joints united. Body elongate, navicular and acuminate 

 at apex. 



This is a small genus, containing only five described species, which 

 are confined in their distribution to the Neotropical Region, and of 

 which, onlv one has been recorded from the West Indies.
