rax, thickish at the base and furrowed, slightly broader 

 to the insertion of the antennae and canaliculate , beyond 

 these its sides are parallel and with a raised line of 

 small teeth; beneath the apical portion is almost smooth 

 and glossy, while the portion between the antennae has 

 a longitudinal keel and the basal part is deeply punctu- 

 red. Antennae distinctly longer than the prothorax and the 

 head with the basal portion of the rostrum taken together ; 

 the first joint stout, clavate and as long as the 2"^^ and 

 S""^ joints taken together, which are very short; the re- 

 mainder subcylindrical, pubescent and almost equal in size; 

 the 1 1*'^ is the longest of all and obtusely pointed at the tip. 



Prothorax about two third the total length of the elytra , 

 conical , narrower anteriorly than at the base , widest be- 

 hind the middle, with the sides rounded and the base 

 transversely furrowed ; above brown , the apical margin 

 blackish , impunctate , very shining. 



The elytra are about as long as the prothorax and the head 

 with the basal portion of the rostrum taken together , 

 broader than the base of the prothorax, the shoulders 

 are rounded, the sides subparallel, but towards the apex 

 attenuated and at the apex emarginate. The elytra are 

 punctate-striate ; the 1^* furrow near the suture impunc- 

 tate , the 2°'^ and S'^'^ with small punctures , the remainder, 

 which are also broader , deeply and regularly punctate , with 

 the punctures approximate and the interstices convex , 

 raised. The maculation of the elytra is the following: the 

 S'*^ interstice near the suture has a basal line covering 

 a space equal to five punctures ; behind the middle , a 

 short line and another near the apex; the 4*^ interstice 

 has a line equal to three punctures towards the middle , 

 and a shorter line behind the middle; the 5"^ has a line 

 before and another behind the middle; the 6^^ has two 

 lines as the 5*'' ; the 8*^'' a line before the middle ; the 

 9*^'' has a line before the middle and another near the apex. 



The undersurface of the body is brown-red , impunctate, 

 shining; the metasternum and the two basal segments of
