 black stripe and the margins of the fastigium more or less marked with 

 black ; vertex very gently tumid, hardly elevated above the pronotum, 

 the interspace between the eyes slightly wider than (male) or nearly 

 twice as wide as (female) the first antennal joint; fastigium strongly 

 decliveut, heavily (male) or broadly and rather shallowly (female) sul-

 testaceous (male) or ferruginous (female), about four-fifths (male) or 

 three-fifths (female) as long as the hind femora. Pronotum subequal, 

 scarcely enlarging posteriorly, the disk nearly plane but feebly convex, 

 passing by a well-rounded angle into the slightly tumid but vertical 

 lateral lobes, the median carina distinct and sharp on the metazona, 

 subobsolete on the prozona, the disk ferrugineo-testaceous, punctate 

 with fuscous, especially in the female, the lateral lobes luteo-testaceous 

 with a broad piceous band on the upper part of the prozoua, in the
