(Plates I, fig. 6; XV, fig. 6.)

Very dark testaceous, much infuscated, especially above. Head not 

 prominent, luteo-castaueous, more or less clouded or blotched with 

 fuscous, above wholly fuscous, with a narrow, posteriorly broadening, 

 testaceous stripe, following the posterior upper edge of the eye and 

 separating the vertex from a piceous or blackish fuscous postocular 

 baud; vertex gently tumid, very slightly elevated above the prouotum, 

 the interspace between the eyes rather broad, nearly (male) or fully 

 (female) twice as broad as the basal antenna! joint; fastigium steeply 

 declivent, broadly sulcate throughout; frontal costa rather prominent, 

 as broad as the interspace between the eyes, equal, percurrent or almost 

 percurrent, punctate especially laterally, feebly sulcate at and below 

 the ocellus; eyes moderately large, not very prominent, anteriorly sub- 

 truncate, a little longer than the infraocular portion of the genae; 

 antennae luteo-ferruginous, gradually and slightly infuscated apically, 

 about three-fourths (male) or two thirds (female) as long as the hind 

 femora. Prouotum subequal, feebly enlarging on the metazona, ferru- 

 gineo- testaceous, much infuscated on the disk, the lateral lobes with a 

 broad, more or less distinct, dark, sometimes piceous band crossing the 

 prozona above; disk nearly plane, passing by a tolerably distinct but 

 rounded angle into the anteriorly slightly tumid vertical lateral lobes; 

 median carina slight, percurrent, somewhat feebler and blunter on the 

 prozona than on the metazona; front margin subtruncate, hind margin 

 obtusangulate; prozona quadrate, sometimes feebly longitudinal in the 

 male, scarcely if any longer than the closely but feebly punctate meta- 

 zona. Prosternal spine rather stout, moderately long, appressed conical, 

 blunt, feebly retrorse; interspace between mesosternal lobes fully half 

 as long again as broad (male) or slightly transverse (female). Teguiina 

 reaching and sometimes a little surpassing the tips of the hind femora, 

 moderately slender, distinctly tapering, brownish fuscous, distinctly 

 but not conspicuously maculate in the discoidal area; wings hyaline, 

 with mostly brownish fuscous veins. Fore femora of male not greatly 

 tumid; hind femora flavo-testaceous, twice broadly and very obliquely 

 banded with blackish fuscous, with a basal patch of the same, all some- 

 times confluent on the outer face, which it then nearly fills, the lower 

 face and lower half of inner face immaculate, the genicular arc black; 

 hind tibiae faintly valgate, red with an inconspicuous fuscous patellar 

 spot, the spines black except their pallid bases, ten to twelve, usually 

 eleven, iu number in the outer series. Extremity of male abdomen
