very slightly convex, never abruptly ampliate at 

 the base. 



130 (141). Interspace between the mesosternal lobes of the female 



decidedly transverse, sometimes twice as broad as 

 long; of the male occasionally transverse, frequently 

 quadrate or subquadrate ; tegmina lobiform, linear, 

 or wanting. 



131 (132). Interspace between the mesosternal lobes of male 



decidedly transverse, as broad as, or broader than, 

 the lobes themselves ; pronotum without lateral 

 carinse Netrosoma, Scudder. 



132 (131). Interspace between the mesosternal lobes of male 



quadrate or subquadrate, or, if feebly transverse 

 (Paradichroplus), not as broad as the lobes them- 

 selves, and then the pronotum is furnished with 

 lateral carinse ; the tegmina ovate or linear. 



133 (138). Last ventral segment of the male abdomen elongate, 



extending well beyond the apex of the supra-anal 

 plate. 



134 (135). Tegmina and wings usually complete, as long as or 



longer than the abdomen. Hind margin of the 

 pronotum angulate or rounded; apex of the last 

 ventral segment of the male abdomen without an 

 apical tubercle Dichroplus, Stal. 



135 (134). Tegmina and wings abbreviate, lateral. Hind margin 



of the pronotum truncate ; last ventral segment 

 pyramidal, pointed, a slight tubercle extending 

 beyond its posterior margin. 



136 (137). Body comparatively slender; pronotum provided with 



lateral carinse ; metasternal lobes of the male nearly 

 approximate; prosternal spine transverse. Tip of 

 the male abdomen neither clavate nor upturned ; 

 furcula present . . . . . . Paradichroplus, Brunner. 



137 (136). Body rather robust ; pronotum rugose, without lateral 



carinas; prosternal spine stout, cylindrical; meta- 

 sternal lobes of the male about one-half as distant 

 as the mesosternal lobes. Tip of the male abdomen 

 clavate and upturned; furcula wanting ...... Dasyscirtus, Bruner. 



138 (133). Last ventral segment of the male abdomen more or less 



conically protuberant apically, but its interior apical 

 margin not or barely surpassing the apex of the 

 supra-anal plate. 



139 (140). Apical tubercle of the subgenital plate small, extending 



but a short distance beyond the supra-anal plate;
