 3rd slightly clavate, the 2nd 2^ times as long as the 1st, the 3rd fths

 longer than broad, triangular, slightly convex. Elytra ; Clavus de- 

 flected to the corium, with 3 straight rows of contiguous distinct 

 punctures, and sometimes other irregularly disposed punctures 

 between the inner and the next row. Corium; anterior margin 

 narrow, reflexed, 1st 3rd nearly straight, last 3rd curved in- 

 wardly ; disk slightly convex, on the inner side with punctures 

 disposed in rows, outwardly more irregularly punctured ; posterior 

 margin nearly straight ; Membrane with 5 nerves, the 1st 3 curved 

 inwards, posteriorly divergent, the other 2, arising near to each other 

 near the inner basal angle, curving outward, then inward, and then 

 slightly divergent. Sternum; Mesosternum in front compressed into 

 a short middle keel ; from the middle to the end of the xyphus flat.
