Ilah. ]5razil. 



Dark brown, with a greyish pubescence. Prothorax 

 strongly and somewhat rugosely punctured ; tli3 sides nearly 

 parallel ; the disk with a short feeble carina in the middle. 

 Elytra i'ulvous, opaque, sparsely punctulate, with very short 

 yellowish setiB springing from the punctures, with the extreme 

 lateral and apical margins and two spots on each dark brown ; 

 of these spots one (oblong) is placed under the shoulder in 

 contiguity with the outer margin, the other (rounded) is situ- 

 ated on the disk a little behind the middle ; apices of the 

 elytra truncate, each with two moderate-sized spines. Inter- 

 mediate femora unidentate ; posterior bidentate at their distal 

 extremity. Tibiee spined at their outer termination. Inter- 

 mediate cotyloid cavities open externally. 



This species seems nearly enough related to the preceding 

 one, and for similar reasons must be placed in Criodion.
