 the borders of the sterna, the apices of the femora, the second 

 anteunal joint and the bases of the next three or four, also of a 

 blackish or dark brown colour. Head finely and rather densely 

 punctulate. Antennae not extended past the middle of the elytra 

 in the c?, shorter still in the $ ; third and fourth joints somewhat 

 globular, the third broader and a trifle longer than the first or 

 fourth ; fifth obconic, narrower than the fourth ; all these joints 

 subnitid, minutely and rather densely punctured, the punctures 

 with very short tawny setae-; sixth to tenth similarly punctulate 

 and setose posteriorly, but covered densely with short tawny 

 pubescence on the flattened part in front. Prothorax only slightly 

 rounded at the sides ; strongly wrinkled above, the ridges more or 

 less regularly transverse ; front and hind borders narrowly black. 

 Elytra somewhat dull, covered with short pubescence ; the dark 

 brown bands, one of which runs along the suture and another at 

 the outer margin, are somewhat broader than the intervening red 

 bands, the two inner of which are feebly raised.
