longer than the head and thorax together; palpi pale 

 pitchy. Thorax one-third broader than long, rather nar- 

 rowed in front, very thickly and coarsely punctured, with 

 a well-marked mesial impressed line, and two distinct 

 oblong impressions near the scuteUum; anterior margin 

 arched, slightly bordered ; the posterior angles acute ; the 

 sides a little rounded in fi^ont. Surface of the elytra very 

 uneven, deeply and rather thickly punctured, the intervals 

 between the punctures shining and raised ; each elyti"on 

 has four rather irregular costse, which are united at 

 irregular intervals by transverse costse.

Head with rather strong punctures, not very close 

 together. Thorax considerably narrowed in front, en- 

 larged at the posterior angles (which are nearly right 

 angles), very closely and rather rugosely punctured in 

 front, more finely behind ; there is a well-marked mesial 

 line (which does not extend to the base), there is a rather 

 deep wide fovea on each side of the disk, which being 

 united with the usual impression within the posterior 

 angle forms a well-marked oblique impression on each 

 side, there is also an impression near the scuteUum. The 

 elytra are a little less dark than the head and thorax, 

 rather closely and very distinctly punctured ; each elytron 

 has three distinct costas.
