throughout; hind margin of pronotuni subtruncate; tegmina shorter than 



pronotum; liind tiliiie glaucous; male cerci very slender and apically

( )f small size, rather slender, fu-^cous or t'usco-testaceous, rarely tes- 

 taceous, dull flavous beneath, with a broad piceous postocular stripe 

 crossing the proz-ona. Head not prominent, testaceous or plumbeo- 

 testaceous, much flecked with fuscous, especially above where it is al- 

 most wholly fuscotis, the upper margin of the postocular stripe edged 

 narrowly with testaceotis ; vertex tumid though elevated but little 

 above the pronotum, the interspate between the eyes half as broad 

 again (r{*) or twice as l)road ( 9 ) as the first antennal point; fastig- 

 ium steeply decliven*;, strongly (d^) or scarcely (?) sulcate; frontal 

 costa almost percurrent, subequal but faintly narrowing above, about as 

 wide as the interspace between the eyes, faintly sulcate at the ocellus, 

 biseriately punctate above; eyes moderate, somewhat prominent in 

 the male, much longer than the infraocular portion of the gens ; an- 

 tenn;€ casteneous, luteous at base, often infuscated apically, about two- 

 thirds (cT) or hardly half (9 ) as long as the hind femora. Pronotum 

 subequal (c?) or feebly enlarging from in front backward (9), fus- 

 cous but below the postocular stripe plumbeo-luteous, sometimes infus- 

 cated, the disk convex, passing by a faint angulation, in the female 

 simulating lateral carinae, into the vertical lateral lobes, which in the 

 male are faintly tumid on the prozona ; median carina distinct, per- 

 < urrent, equal; front margin faintly convex (cJ*) or truncate (9 ), 

 hind margin very broadly convex or subtruncate ; prozona strongly 

 ( d^ ) or scarcely ( 9 ) longitudinal, fully half (cJ* ) or about one-third 

 ( 9) as long again as the scarcely more punctate metazona. Proster- 

 nal spi"e small, subconical (c^), or conical (9), blunt, slightly re- 

 trorse; interspace between mesosternal lobes somewhat longer than 

 broad (r^) or decidedly transverse (9), metasternal lobes attingent 

 (cf ) or approximate (9). Tegmina a little short'^r than the pro-
