somewhat caudad; face considerably retreating, the angle of the face 

 and fastigium truncate; frontal costa slightly expanded between 

 the antennae, regularly expanding from slightly 

 dorsad of the ocellus to the clypeal suture, deeply 

 punctate between the antennae, sulcate ventrad, 

 the portion dorsad of the ocellus quite deeply so; 

 lateral carinae of the face distinct, considerably 

 diverging ventrad; eyes subovate, slightly angu- 

 late dorsad and ventrad, moderately prominent 

 when viewed from the dorsum; antennae half 

 again as long as the head and pronotum together, 

 proximal third Avdth the joints distinctly de- 

 pressed and somewhat ensiform in appearance, 

 distal segment depressed, hastate, remaining 

 joints simple, cylindrical. Pronotum somewhat 

 longer than the dorsal length of the head ; cUsk very 

 sHghtly tectate, cephalic margin subtruncate, 

 caudal margin obtuse-angulate with the 'sides of 

 the angle roundly emarginate; median carina 

 distinct, moderately elevated, divided very 

 slightly caudad of the middle, lateral angles of 

 the pronotum not carinate except for limited areas in the vicinity of 

 the cephalic and caudal margins, the form of the lateral angles, as 

 indicated by imperfect carinae, is similar to that of F. hohlsii, being 

 distinctly constricted cephalad of the middle; lateral lobes of the
