COLKOPTERA. 283 



Calleida, Dej. 



Entirely similar to Cymindis, with the exception of the tarsi, the 

 penultimate joint of which is bifid; in the preceding it is triangular. 

 Peculiar to America(!). 



Demetrias, Bon. 



Analogous to Calleida in the tarsi, but having an oval head nar- 

 rowed posteriorly, and all the exterior palpi nearly filiform, with 

 the last joint almost ovoid or subcylindrical. 



This subgenus, as well as the next, is composed of very small 

 species, which usually frequent wet places. They are, nearly all, 

 European(2). 



Dromias, Bon. 



Generally apterous; joints of the tarsi entire; otherwise similar to 

 Demetrias(3). 



There, the thorax is evidently wider than it is long, forms the 

 segment of a circle, or resembles a heart, widely and transversely 

 truncated posteriorly. 



In some, the middle of the posterior margin of the thorax is ex- 

 tended backwards. Such is 



Lebia, Lat. — Lebia Lamprins, Bon. 



Exterior palpi terminating in a little larger and nearly cylindrical 

 or oval joint truncated at the end; four first joints of the tarsi almost 

 triangular, and the fourth more or less bifid or bilobate. One of the 

 most common in Europe is

 above; first joint of the antennae, the feet and thorax, fulvous- 

 red; extremity of the femur black; elytra marked with slight 

 punctated striae.
