 elytra ; fii*st joint twice as long as it is broad, closely and coarsely 

 punctured ; third more than twice as long as the first and equal 

 in length to the fourth, fifth and two-thirds of the sixth united,

 short. Pronotum about one-fifth broader at the base than at the 

 apex, very closely and finely punctate and opaque, but with two 

 triangular spaces before the middle, a small rugose spot external 

 to each of these, a narrow transverse band near the base, a median 

 streak from the middle and an oblique rugose band from each end
