356 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL.XX. 



Dark brownish fuscous, the upper half of the lateral lobes of thepro- 

 notum aud especially of the prozona generally distinctly darker than 

 the lower, often forming a broad dark band. Head brownish fuscous, 

 lighter below, irregularly flecked and mottled with fuscous, gently tumid 

 above ; interspace between the eyes broad, but narrower than the frontal 

 costa, the fasti gium plane but with the margins feebly and roundly 

 elevated at its narrowest, broadening in front and passing insensibly 

 into the frontal costa 5 the latter very broad, subequal, not at all con- 

 stricted above, shallowly sulcate at and below the ocellus, feebly punc- 

 tate; eyes elongate oval, narrower above than below, but little prom- 

 inent; antennae about as long (male) or hardly three-fourths as long 

 (female) as the hind femora, rather slender, fulvo-testaceous. Prono- 

 tum scarcely enlarging posteriorly, the disk nearly plane, with rounded 

 lateral carinae separating it from the vertical lateral lobes, the prozona 

 barely longitudinal (male) or barely transverse (female), about a fourth 

 (male) or less than that (female) longer than the metazona, the median 

 carina subobsolete between the sulci and more distinct on the metazona 

 than on the prozona, the front border barely convex, the hind border 

 broadly convex or more frequently obtusely angulato-convex, its promi- 

 nence slightly variable, the principal sulcus not quite transverse by the 

 slight emargination of the posterior border of the prozona, ferrugineo- 

 testaceous, profusely and finely flecked with fuscous, rather feebly punc- 

 tate even on the metazoua, the lateral lobes with a sometimes obsolete, 

 generally somewhat obscure, dark fuscous band, in extreme cases ex- 

 tending from the eyes across the whole pronotum and occupying nearly 

 the whole upper half of the lateral lobes ; thoracic epimera black. Pro- 

 sternal spine stout, rather long, cylindrical, tapering only at the rounded 

 apex, somewhat retrorse. Tegmina always abbreviated, distinctly 

 shorter than the abdomen or the hind femora, generally a little longer 

 than the head and pronotum together, dark fuscous, the anal area some- 

 times much lighter, the discoidal area flecked somewhat confusedly 

 with mingled blackish and light testaceous, the apex bluntly acuminate. 

 Hind femora moderately stout and rather long, testaceous, varying 

 from cinereous to dull flavous, broadly bifasciate with black, the genicu- 

 lar arc black on both sides; beneath they are normally flavous or ful- 

 vous; hind tibiae dull red, with a narrow, subbasal, black annulus, next 

 which they are more or less obscured with fuscous, sometimes forming 

 a dusky belt half way to the tip, the spines black almost to the very 

 base, ten to eleven in number in the outer series. Posterior extremity 

 of male abdomen feebly clavate, well rounded, the supraanal plate 

 rounded triangular with a feebly produced tip, nearly flat, the median 

 sulcus percurrent, slender, moderately deep, bounded by low rounded 

 walls which extend over about three-fourths of the plate; furcula want- 

 ing, the last dorsal segment narrow and narrowly parted in the middle; 

 cerci heavy, broad, punctate except apically, externally broadly convex, 

 the basal two-fifths nearly equal, beyond expanding rapidly and con-
