margin decidedly angulate in the middle. The lobes of the mesoster- 

 num are separated by a space longer than broad (male). The meta- 

 sternal lobes are contiguous. The tegmina and wings are well devel- 

 oped and not longer than the abdomen. In both the ulnar area is 

 very greatly expanded in the middle and the discoidal area is narrow. 

 The posterior femora are not banded. The posterior tibiae have the 

 apical spurs on the inner side not very une(iual. The anterior and 

 middle femora are somewhat inflated.

Vertex nearly horizontal, never extending in front of the eyes a 

 distance greater than its own width, always more or less sulcata, with 

 or without a faint median carina. The lateral foveolse are obsolete or 

 distinct, elongate triangular, or linear, not visible from above. The 

 frontal costa is plain or sulcate with the sides nearly straight and very 

 moderately divergent. The face is nearly straight or a little arcuate, 

 never at all sinuate. The antennse are filiform, sometimes depressed 

 and acuminate at the apex. The pronotum has the disk nearly plain, 

 with the median carina cut in or behind the middle. The lateral car- 

 inge are generally decidedly or strongly sinuate, rarely nearly straight 

 and divergent from the front border, or from the first and second sul- 

 cus. Very rarely they are nearly parallel. The lateral lobes of the 

 pronotum have the anterior border decidedly oblique and straight or 

 a little arcuate, the posterior l)order is less oblique and more or less 

 sinuate and the lower border is decidedly angulate in the middle. 

 The mesosternal lobes are separated by a space broader than long (fe- 

 male) or about as broad as long (male) and the metasternal lobes by a 

 space not broader than long (female) or they are contiguous (male). 

 The tegmina and wings are well developed, a little shorter or much 

 longer than the abdomen. The former are very narrow with the 

 scapular area not more expanded in the male than in the female. The 

 discoidal area is destitute of the intercalary vein and the ulnar 

 area in the male is sometimes much widened and regularly reticulate. 

 The posterior femora are moderately slender or rather heavy. The
