This sperie.H and the next are less stronglv flattened than any of the preceding inendiers 

 of the gpniis; they have the posterior plate of the prosterniim strongly tapered Udiiml 

 and have the rlypens entirely hithlen ; the outer tuUertles are variable in size, hut are 

 jip'hahly always somewhat long and slen<ler in unworn specimens, and the frontal ridges 

 are «»l»so|ete In'tween them and the inner tulK-rcles, though well developed between the 

 inner tulwreles and rentral tuljenle. The anterior angles of the head are sometimes 

 rather .strongl> pnuluied and aeute. The .sides of the pronotum are more exteimively, 

 and the grooves of the I'lytra more coarsely punctured than in /'. Irachii, which this species 

 resembles in other respects, except that the shoulders of the elytra are entirely hairle.s.4. 

 The tibiae of the intermediate (an<l to a les.s extent the hind) legs often bear several strong 

 .spines on the <i\iter side, esj)e«Mally in small spe<imens.

 instead of meeting abruptly, in having the anterior extremities of tlw marginal grooves
