FoLEJvGus, gen. nov. 



Body longer than broad, slightly convex, thickly and minutely punctate ; head 

 about as long as breadth between eyes, which are distinctly substylately produced, an 

 obscure tuberculous spine on each side in front of eyes ; central lobe slightly projecting 

 beyond the lateral lobes, apices of lateral lobes rounded ; antennse four-jointed, hrst 

 joint thickened and about reaching apes of head, second thickened, compressed, 

 obscurely sulcate, and considerably the longest, third and fourth shorter, subequal in 

 length, but each longer than first ; rostrum passing the posterior coxge ; pronotura 

 broader than long, anterior and posterior margins subtruncate, the lateral margins 

 oblique and moderately sinuate ; scutellum not passing the middle of abdomen, about 

 as long as broad at base, apex rounded ; abdomen beneath moderately centrally 

 longitudinally sulcately impressed on basal half, spiracles on the basal ventral segment 

 exposed, not hidden by the metastenmm, and placed on the segmental margin ; legs 

 moderately stout, femora with a rudimentary tuberculous spine beneath at apex; tarsi 

 two-jointed ; membrane almost reaching abdominal apex, about as long as corium, 

 with five longitudinal veins becoming much ramified at a short distance from base. 



I place this genus near Thalma Walk., from which it diff'ers in the different position 

 of the lobes of the head, the porrect eyes and the short tuberculous spine in front of 

 them, longer rostrum, etc.
