The anterior margin of the head is nuiih niore extensively notehetl in the middle line 

 than in the pre«e«ling species, and the notch is hounded by a pair of very prominent 

 tuhercles. The.se tuherdes are fully as .strong as the outer ttdiercles. which are .somewhat 

 »mall and are more or le.ss oh.scured l>y the inner tuhen les. the latter hcing very liuig and 

 pr»)jecting from a point contigu«)Us to and a little liehiiul ami on the outer side of them. 

 From the inner tui.ercles the imperfectly denti(uiate frontal ridges extend in a straight 

 line backwards and inwards to meet in a right or .-.lightly ul.tuse angle. The anterior part 

 ol the frontal area is moie or less punctured. 



The proncttum resend)les that of the preceding species in shape and is more or less 

 exten.sively puncture«l at the si«les. hut the anterior ends of the nuirginal grooves are not 

 cxpande«l. The mesothorax is nornuil. The posterior interme<liate areas of the 

 metasternum are do.selv and coarsely puncture<l : the lateral area-s are moderately hroad 

 and are covere«l with hair-hearing punctures. The dor.sal grooves of the elytra are 

 strongly hut finely punctured, the lateral grooves ,ire coarsely punctured. The epipleura 

 shoulders and anterior half or two-thirds of the (»titermost rih of the elytra are thickly 

 covered with hair-hearing ptnu tures. The middle tihiae are armed with one stout spine.
