 a ferruginous tinj^e ab<»ve, riavous heneatii. IIea<l not at ail prominent, 

 olivaeeo-riavous more or less infuseated. above fuscous, with a broail 

 piceous postocular baud; vert«'X hardly at all tumid, not raised above 

 the level of the pnuiotuni. scarcely or not reachin*^ the level of the 

 upper arch of the eyes, the interspace between the eyes very narrow, 

 hardly as broad as the tirst antennal Joint; fasti^nuni steeply declivent, 

 feebly sulcate, oblonji ob])yriforra; frontal costa percurrent, ecptal, 

 scarcely broader than the interspace between the eyes, feebly sulcate 

 at an<l below the ocellus, faintly punctate; eyes larj::e, very [)romiiient, 

 nearly twice as long as the infraocular i)ortion of the jreuae; antennae 

 testaceous at l»ase. l*ronotuni lon<»', equal, with a scarcely perceptible 

 expansion of the metazona, brownish fuscous above, tlavous or Havo- 

 tcstaceous on tht sides, with a rather broad, iJercurrent. piceous, jjost- 

 ocular band, narrower on the metazona than on the prozona, the disk 

 considerably convex ami passin*;* with only a feeble shoulder into the 

 vertical lateral lobes; median carina distinct, sharp, e(iual. percurrent; 

 front nuu jj;in feebly convex with the faintest possible emar<:fination, 

 iiind niarj^in subtruncate; prozona very longitudinal, nearly cwice as 

 long as the densely and sharply punctate metaz<»na. Prosternal spine 

 moderate, slender, conico-cylindrical, blunt, erect: interspace between 

 mesosternal lobes a little longer than broad. Tegniina abbreviate, 

 shorter tlian the pronotum. attingent or subjittingent, ovate, well 

 louiuled apically, less than twice as huig as broad, brownish fuscous. 

 I'ore and middle femora somewhat tumid in the male; hind femora 

 tlavous. sometimes more or less ferruginous, the wlnde geniculation 

 except the apical portion of the lower lobe black: hin<l tibiae pale 

 greenish or pale glaucous, the spines l)lack to their base, fourteen to 

 litteen in number in the outer series. Extremity of male abdomen 

 considerably clavate, recurved, the supraanal plate clyjjeate with 

 rectangulate tip, raised and sinuate lateral nuirgins, a narrow, deep, 

 percurrent. median sulcus, the walls of which ar»^ hardly elevated into 

 ridges, and an apical pair of short, convergent, blunt ridges; furcula 

 consisting of a pair of basally attingent. divergent, slender, tapering, 

 acuminate lingers, crossing rather more than a fourth of the supraanal 

 plate; cerci composed of a moderately broad, rajudly tapering, slightly 

 tumid, basal portion, about one-third of the whole, and a very slender, 

 snbcqual, gently arcuate, incurved, and apically faintly expanding por- 

 tion, hardly nunc than a third as broad as the base, inferiorly angulate 

 at tip and reaching about to the tip of the sui)raanal plate: subgenital 

 I'late small, greatly tai)ering, so as to be very narrow at tip, the apical 

 margin considerably elevated to form a delicate t-ubercle.
