and more prominent. The prothorax is distinctly less strongly 

 (though nevertheless strongly) transverse, and is very evidently 

 more narrowed behind ; its sides are distinctly though slightly (in 

 brevis not at all) sinuate immediately in front of the base ; and 

 the base itself differs as follows : — In sinuatics it runs as a 

 continuous curved (nevertheless sinuous) line from one hind angle 

 to the other (the convexity of the curve directed hindward), and 

 there is nothing at all like a median lobe distinguished from the 

 rest of the base, while in brevis the middle part of the base forms 

 a very wide and quite well defined lobe.

Dystrichothorax, gen.nov. 



Ab Amblytelo differt prothorace utrinque i)unctura setigera 

 singula solum instructo, hoc ad angulum posticum posito. 



All the species that I have seen of this genus differ from all 

 that I have seen of Amblytelus in their prothorax being much 

 wider behind. The subapical intra-marginal carina of the elytra 

 is as in Amblytelus. In the male the front tarsi are but little 

 dilated, the basal 3 joints having scale-like papillfe beneath. 

 Amblytelus amplijjennis, Macl., belongs to this genus.
