COLEOPTERA. 377 



Dromias, Bon. 



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

 Demetrias. 



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

 ment of a circle, or resembles a heart, widely and transversely trun- 

 cated posteriorly. 



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

 tended backwards. Such is 



Lebia, Lat. — Lebia Lamprias, 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

 in length ; body fulvous with black elytra, terminated by a yel- 

 lowish-fulvous spot ; elytra slightly striate, the striae punctuate, 

 with two more deeply impressed puncta near the third, com- 

 mencing from the suture *. 



In the foUoAving, the thorax terminates posteriorly in a straight 

 line without any central projection. 



Plochionus, Dej. 



The antennae almost granose ; last joint of the labial palpi large, 

 nearly securiform; four first joints of the tarsi short, in the form of a 

 reversed heart, the fourtli bilobate f. 



Orthogonius, Dej. 



Similar tarsi ; but the antennae are filiform, and the external palpi 

 terminated by an almost cylindrical joint :]:.
