 from base to apex, nearly t\v«> tliirds (male) or tliree-tiftlis (feinah') as 

 long as the liln<l femora. Pronotiim suhe(|nal, faintly expandinji pos 

 teriorly, the disk ferrugineo fuscons. sometimes testaceous tleekcd with 

 tuseous, j;eiitly <*onvex transversely and passing by an abrupt but 

 nmnded shoulder, seareely forming lateral earinae, into the slightly 

 tnmi<l subvertieal lateral lobes; these aie Ha vo testaceous on the lower, 

 pieeous on the ujjper half, the division line between the colors .vhnrp. 

 arcuate; median carina shar|) and distinct on metazona, feeble on 

 prozona, and sometimes obsolete between the sulci: front margin trun- 

 cate, hind margin feebly proilueed, subtruncate; i)roz()na distantly, 

 ( oarsely, and shallowly i>unetate, feebly convex anteroposteriorly, 

 longitiidinal, nearly one half (male) or about one third (female) long^'r 

 than the closely and rather finely punctate metazona. Prosternal 

 si)ine small, stout, conical, and rather sharply pointed (male) or blunt 

 (female); intersj)ace between mesosternal lolx-s fully half as long again 

 as broad (male) or fully half as broad again as long but narrower than 

 the lobes (fennile): ridge of metathoracic episterna tlavous like the 

 mesothoracic, i)iceous between. Tegmina abbreviate, shorter than the 

 pronotum, in the female scarcely longer than the jjrozona, very broadly 

 ovate, very broadly rounded apically, attingent or subattingent, brown 

 ish fuscous, the anal area often cinereous. Fore and middle femora 

 very tumid in the male; hind femora rather stout and plum}), ferrugineo- 

 testaceous, sometimes immaculate, sometimes obscurely and brokenly 

 trifas(*iate with blackish fuscous above, sometimes the whole outer face 

 completely infuscated (the earinae sometimes tlavescent). the inferior 

 surface tiavous or pale sanguineims, the geniculation feebly infuscated: 

 hind tibiae very dark glaucous or bronze green, sometimes with a nar- 

 row fuscous i)atellar annulus, the spines long, ])allid on basal, blackish 

 on apical half, ten to eleven, rarely nine or twelve, in the outer series. 

 Abdomen tiavous, testaceous or ferruginous, the sides marked with 

 piceous, in the male sharply delimited in a narrowing baud; extremity 

 in the nmle clavate, considerably recurved, the sui)raanal ])latetriangu 

 lar, expanded at extreme baee, the apex acutangulate, the lateral mar- 

 gins broadly elevated, the median sulcus very broad at base, rapidly 

 narrowing so that at and beyond the middle it is very slender, the 

 arcuate bounding ridges high and shari>; furcula reduced to the slightly 

 projecting inner angles of the divided halves of the last dorsal segment ; 

 cerci strongly comi)ressed, very broad and rounded on basal half, with 

 nmrginal borders, and a little tumid in the middle, the apical half sub 

 cylindrical, slender, tapering, pointed, not one-third the width ol the 

 base, the whole not more than half as long again as broad and hardly 

 attaining the tip of the supraanal plate; subgenital plate much longer 

 than broad, with very convex lateral margins, deeply hollowed and 

 entire apical margin, the margins <iuadrate as seen from above.
