CURCUL lONID JE. 



[LeConte. 



BARIS Germ. 



As I have here restricted this genus, it contains only those species in 

 which the club of the antennae is small, nearly round, with the first joint 

 not sensilive, shining, and constituting more than one-half the mass. The 

 claws are separate, divergent, and of moderate size, and in some of the spe- 

 cies {sparsa, &c.) small. Tlie beak is stout, usually short, and much curved; 

 the frontal constriction rather deep; sometimes it is a little longer tlian 

 the prothorax. The front coxjs are never very widely separated; the pro- 

 sternum is flat or broadly sulcate according to species. Tlie pygidium is 

 vertical, and the fifth ventral is but little longer than the fourth. Tibia; 

 strongly mucronate at tip. The species are glabrous or very slightly and 

 sparsely pubescent.

Wisconsin, Kansas, New Mexico. This species resembles in form and 

 sculpture B. carinulatns and others in that neighborhood, but is easily 

 known by the prosternum being narrow^ between the coxae, and flattened
