margin broadly excavate for nearlj' all the length and striate on 

 the upper declivity as well as in the excavation, outer basal angle 

 broad; anterior part of prothorax lenticular, incised in the 

 middle, but not aculeate laterally cucullatus. 



Head plane and with two small tubercles on vertex ; club as 

 in the preceding species but with the apical part a little more 

 acuminate and with the outer basal angle sharper and longer ; 

 anterior part of prothorax with a sharp lateral spine ruber. 



Club compressed and laininate for half the length, the outer 

 margin broadly scooped out at the apex, the upper edge with 

 five slightly projecting ridges ; anterior part of prothorax sub- 

 aculeate laterally cochlearms. 



Club with the inner margin sharp, quadri-impressed, a little 

 sinuate, outer margin scooped from base to apex, and with five 

 striae denting slightly the edges ; anterior part of prothorax not 

 aculeate viator.

Posterior tibiae slender. 



Club with two basal striae in the inner margin, outer margin 

 broad, excavate and with five ridges in the excavation projecting 

 as a rounded denticulation beyond the edges, basal outer angle 

 as long as the whole base, narrow and cylindrical ; anterior part 

 of prothorax with a sharp spine on each side burchcUianus. 



Club laminate in the inner and basal margins, with the outer 

 margin enlarged and broadly excavate from the basal angle to 

 the apex, lower edge of the excavation broader than the upper, 

 the latter sinuate near the apex, both edges slightly striate in- 

 wardly ; head with four rounded tubercles on vertex ; posterior 

 tibiae a little dilated in the median part rugiccps.
