a little longer than the rather feebly punctate metazona. Prosternal 

 spine short, transverse, apically subtruucate; interspace between nieso- 

 sternal lobes a little transverse, much narrower than the lobes, alike in 

 both sexes, the metastemal lobes subattingent (male) or rather distant 

 (female). Tegmina abbreviate, about as long as the pronotum, attin- 

 gent, ovato-fusiform, broader in the female than in the male, apically 

 acuminate, blackish ferruginous. Fore and middle femora considerably 

 tumid in the male; hind femora very dull brownish testaceous, heavily 

 bifasciate with blackish fuscous, the premedian fasciation angulate on 

 the outer face, the whole geniculatiou, except sometimes the tip of the 

 lower genicular lobe blackish, the inferior face dull flavous; hind tibiae 

 red, the extreme base and a subbasal annulation fuscous, the spines 

 black almost to their very base, ten in number in the outer series. 

 Extremity of male abdomen distinctly clavate, considerably recurved, 

 the supra anal plate triangular with slightly convex, basally-raised 

 lateral margins, acutangulate apex and moderately broad and deep 

 equal median sulcus extending over a little more than the basal half of 

 the plate, its bounding ridges sharp and moderately high ; furcula con- 

 sisting of a pair of approximate, slight but rather coarse, parallel 

 denticulations, shorter than the last dorsal segment; cerci rather small, 

 subfalcate, being slightly curved upward but not incurved, tapering 

 somewhat in the basal half, beyond equal and two-thirds as broad as the 

 extreme base, the tip well rounded, shorter than the supraanal plate; 

 subgenital plate small, subconical, apically subtuberculate, moderately 

 narrow, subequal, the margin as seen from above well rounded, entire. 



Length of body, male, 19 mm., female, 26 mm. ; antennae, male, 9 mm. ; 

 tegmina, male, 5 mm., female, 5.5 mm.; hind femora, male, 9*5 mm., 

 female, 11.5 mm.
