Varying from light ferrugineo testaceous tlsroiigh ciiiereo lu8<*ous to 

 dark brownish fuscous with a ferru^'inous tinge, thinly i)ilosc. Head 

 slightly luoininent, plumbeo-testaceous, more or less infnscjited, some- 

 times tlecked profusely aud minutely with fuscous, al)()\e darker and 

 generally more uniform than elsewhere, often blackisli tnscons, with a 

 postocular piceous bind; vertex gently tumid, slightly elevated above 

 the pror<.tum, the interspace betweei» the eyes moderate, a little broader 

 than (male) or twice as brond as (lomale) the first antei.nal Jcint; fas- 

 tigium rather strongly decliveiit, sulcate throughout; frontal costa 

 rather i)r'^*minent above, but not contracted, Just failing to reach the 

 clypeus, feebly broadening below, fully as broad as tiie interspace 

 between the eyes, shallowly sulcate at and generally below the ocellus, 

 punctate above; eyes large, prominent, particularly in the male where 

 they rise above the level of the vertex, very much longer than the 

 intraocular portion of the genae; antennae luteo-fulvous, four-fifths 

 (male) or about two-thirds (female) as long as the hind femora. Pro- 

 notum subequal, scarcely enlarging on the metazona, the very gently 

 convex disk ])assing, with a pronounced but well rounded shoulder, 

 nowhere forming a lateral carina, into the iuferiorly vertical lateral 

 lobes; the latter are marked above with a broad, equal, rarely broken, 

 piceous band crossing the prozona and sometimes indicated on the 

 metazona by a slight darkening; median carina distinct on the meta- 

 zona, obsolete or subobsolete on the prozona, always obsolete between 

 the sulci; front margin truncate; hind margin broadly obtusangulate, 

 the angle generally broa<lly rounded in the female; prozona quadrate 

 or feebly longitudinal (male) or quadrate or feebly transverse (female), 

 only a little longer than the closely punctata metazona. Prosternal 

 spine short, conical, very bljant, erect; intersi)ace between mesosternal 

 lobes twice as long as broad (male) or considerably longer than broad 

 (female). Pleura with a distinct Havo-testaceous stripe bordered with 

 black following the metathoracic episterna. Tegmina surpassing the 

 hind femora, sometimes considerably, slender, tapering feebly, well 

 rounded apically, brownish fuscous, sometimes immaculate but generally 

 rather sparsely si)rinkled with minute fuscous spots throughout the 

 discoidal area almost or quite to the tip; wings rather narrow, hyaline, 

 often with a very feeble citron tint, most of the veins black or fuscous. 

 Fore and middle femora but little tumescent in the male; hind femora 

 slender and eh)ngate, testaceous or ferruginous, obscurely bifasciate 

 with fuscous, often reduced to a fuscous cloud on the outer face, most 

 of the geniculatiou black, the inferior surface and most of the interior 

 varying from luteous to carmine; hind tibiae light green or glaucous, 

 sometimes blue, with a postbasal fuscous spot or annulus, clothed with 

 sparse pile twice as long as the spines, the spines pallid in basal, black
