Bead strongly transverse, separated from the rostrum by a 

 deep transverse furrow, the eyes lateral, small, subglobuJar and 

 very prominent. Rostrum porrect, short and broad, plane above, 

 angulate laterally, triangnlarly impressed and emarginate at the 

 apex ; the scrobes quite lateral, deep, parallel-sided and curving 

 strongly downwards in front of the eye ; mandibles with a slightly 

 projecting scar ; mentum almost circidar, filling its cavity but 

 sunk below the edges, the submentum with no peduncle. Antemue 

 inserted at or before the middle, the scrobe short, straio-ht, 

 strongly clavate and exceeding the front margin of the eye : the 

 funicle with the two basal joints a little longer, 1 equal to or 

 greater than 2, 3-7 subequal in length but gradually widenino- 

 outwardly, the club 4-jointed, the basal joint the longest, the 

 segments oblique. Prothorax more or less transverse, truncate 

 at the apex, the base truncate or subaugulate, the sides rounded, 

 the gular margin sometimes sinuate. Scutellmn invisible, or 

 minute. Elytra variable in shape, with or without liumeral angles, 

 with 10 striae or sulci, the lateral margins only slightly sinuate 

 above the hind coxae. Sternum with the front coxae nearer the 

 anterior margin of the presternum ; the mesosternum with the 

 epimera narrow and much smaller than the episterna ; the meta- 

 sternum shorter than the median coxae, the episterna distinct 

 but narrow, the hind coxae not reaching the elytra. Venter 

 with the inter-coxal process subangulate or truncate, segments 

 2-4 subequal, 2 separated from 1 by a deep transverse incision. 

 Legs stout, the femora clavate and simple, tlie tibite almost 

 straight externally, the anterior pairs produced inwardly at the 

 apex, the hind pair with the corbels open, but with the external 

 edge sloping inwards ; the tarsi broad, joint 2 short and a little 

 narrower than 1, 3 broadly lobate, 4 elongate, claws small and 

 connate at the base.
