On the male the prothorax is black or almost so, the head is more or less 

 deeply infuscated, the antennae have five or six of the basal joints partly or 

 entirely jiale, the following joiiils !)lackish, the apic.il lialf of the eleventh joint, 

 hoAvever, is conspicuously paler than its ])asal half; the apical half of the femora 

 and parts of the tibiae are also more or less deeply infuscated ; on the female the 

 only dark parts are four or five joints of the antennae (the tips being pale as in the 

 male). The hind tibiae of the male have a narrow impression on the upper- 

 surface, marking off the dilated inner portion. The joints of the club are com- 

 pressed so that, although considerably wider than the prcn-eding joints, from 

 some directions they appear to be of the same width. Tlie X-shaped impression 

 on each side of the prothorax is distinct from most directions, especially on the 

 male, but its parts are of inieven depths. On some parts of the elytra the 

 punctures appear to be slightly geminate in arrangement, but posteriorly their 

 systematic arrangement disappears.
