short, their soles sparsely setose; peiuiltiraate joint entire 

 underneath, excavate above. Claivs simple. 



Prosterniim deeply incurved, the obtuse outer angles of 

 the eraargination representing ocular lobes. Anterior coxa 

 prominent, globose, contiguous, and situated near the hind 

 margin; the intermediate moderately, the posterior widely 

 separated. Metasternuni short, plane or concave. Abdomen 

 narrowed behind, second segment as long as the metasternura, 

 the first much longer; there is a curvate impression between 

 these ; third and fourth very short, with deep straight 

 sutures. 



In some respects Bant'iades approaches this genus; it is, 

 however, well differentiated by the strongly dentiform thighs 

 and seven-jointed funicle. 



Bieosomus tacitus, sp. n. 



Convex, piceous, densely covered above and below with 

 greyish sappy or easily-detached scale-like matter which 

 usually conceals the sculpture. 



Rostrum closely and coarsely sculptured. Thorax rather 

 broader than long, rounded laterally, sonaewhat uneven, 

 coarsely and closely punctate. Elytra broader than thorax 

 at base, truncate in the male, bisiiiuate in the female; there 

 are two slight basal elevations on the third interstices and 

 two small ones on the top of the posterior declivity : the 

 other nodiform elevations are still smaller and inconspicuous, 

 the hinder part is nearly vertical ; they are regularly striate, 

 and the interstices are strongly transversely rugose ; in the 

 female there are series of minute nodules. 



Male. — Rostrum thick, slightly arched, almost parallel- 

 sided. Antennae inserted before the middle. 



Female. — Rostrum slightly narrowed and nearly bare in 

 front of the antennal insertion, nearly one third of the whole 

 length. 



Metasiernum and basal ventral segment flat or broadly 

 impressed. 



Length (rostr. inch) 1-1 5, breadth nearly \ line.
