fulvo-squamosa in medio ornatis ; antennis ferrugineis ; scapo 

 brevi ; prothorace apice tubulate. Long. 2| lin. 



Hah. Parana. 



Subovate, smooth, shining black, in the middle of each 

 elytron a rotmd patch of fulvous scales ; rostrum longer than 

 the head and prothorax together, compressed at the base, 

 strongly curved ; scrobes beginning behind the middle, 

 oblique, meeting beneath ; antennas ferruginous ; scape not 

 nearly reaching the eye ; funicle with the first joint as long 

 as the next four together, the last two closely applied to the 

 club ; prothorax slightly transverse, convex above, tubular at 

 the apex, finely and sparingly punctured ; scutellum sub- 

 quadrate, expanded at the base ; elytra subtriangular, 

 shoulders not prominent, the base not much broader than 

 the prothorax, finely striated, the interspaces flat and nearly 

 impunctate ; body beneath black, smooth, irregularly punc- 

 tured ; legs dark brown, with here and there a minute 

 whitish setiform scale ; tibife straight ; tarsi narrow, except 

 the penultimate joint ; claw-joint elongate. 



Type of Dimesus. Scrobes oblique, meeting beneath the 

 rostrum ; pectus elongate, canaliculate ; anterior coxse apart ; 

 femora mutic ; claws free ; two basal segments of the abdo- 

 men large, the suture obsolete. Differs from Ehianus {Cen- 

 triniis mexicanus) in its shortly ovate facies and obsolete 

 suture. The latter is a semiglobose form like C. tardigradus. 

 Rhianus has the well-developed suture and semiglobose form. 



Centrinus pahnaris.
