smooth, with the space between the eyes very slightly excavate 

 and with the orbital striae wanting or very slightly marked ; 

 frontal sulci near eyes strong and deep and divergent at base ;" 

 between the base of the eyes there are two distinct impressions, 

 which are sometimes confluent ; pronotum often more or less 

 rufescent, subcylindrical, subparallel-sided, very gradually and not 

 strongly narrowed to apex, without a distinct collum, basal con- 

 striction very feeble, upper surface more or less distinctly striolate 

 transversely ; elytra very gradually narrowed towards base, slightly 

 widened behiud and not gibbose in the male, more strongly widened 

 and slightly gibbose in the female, with strong and rugose sculp- 

 ture, which, however, is much less confluent than in the preceding 

 species, and does not form wavy lines ; the punctures are more 

 diffuse at the sides and apex, but are strong throughout ; antenna? 

 very long and slender, pitchy ; legs dark, metallic ; femora, except 

 apex, red. 



Length 15-17 millim.
