Dynamostes. 



Head wider than the thorax, elongated behind the eyes. An- 

 tennae approximate, 11 -jointed, the first thick and nearly twice 

 the length of the third, which is somewhat shorter than the fourth, 

 and nearly equal with the rest, the second excepted. Maxil-

 versely conical. Elytra depressed, wider than the thorax. Legs 

 with the femora very stout, the tibiae unarmed, the posterior 

 deeply notched, tarsi short, claws slender.

 eyes large, ratlier approximate, a wide groove between the eyes, 

 a ridge on each side the groove, and a prominent elevation below
