 pressed as there; the head more swollen. Vertex broadly triangular, 

 the apical half sloping a little downward, the disk noticeably lower 

 than the occiput, the lateral carina"! low; the median present but ter- 

 minating at middle of disk; the foveote distinct, elongate triangular. 

 Frontal costa narrow, strongly sulcate throughour in the male, but 

 only above ocellus in the female. Antennai equaling the head and 

 pronotum together in the female, a third longer in the male; the 

 joints of apical half moderately flattened. Pronotum with its disk 

 nearly flat, the front margin truncate, the hind margin forming a 

 rather sluir])ly marked right angle; the median carina distinct, a little 

 higher on the prozona, cut into two nearly equal halves, by a distinct 

 notch; the lateral carina^ plainly visible only on the metazona. Lat- 

 eral lol)es of pronotum deeper than long, their disks concave and 

 much wrinkled, their front and hind margins nearly vertical, the 

 lower margin with its posterior half rounded, the anterior oblique, 

 ascending. Tegmina rather broad and short, the apex broadly 

 rounded, slightly surpassing the abdomen in both sexes; the inter- 

 calary vein distinctly nearer the ulnar than the median vein. Inner 

 wings short and broad, pellucid or nearly so, the veins next the costal 

 margin distinctly swollen. Hind femora a little shorter than the 

 abdomen in the female; slightly surpassing it in the male.
