tmnid i tciiiiile), at and below the ocellus rather narrowly sulfate, deeper 

 in the male than in the female, i>er<Mirrent, punctate; eyes rather small, 

 not prominent, longer than the intraocular portion of the genae; anten- 

 nae ferruginous, growing lutescent toward the base, dusky toward the 

 tip, nearly or <piite as long (male) or about two thirds as long (female) 

 as the hind femora. Pronotum subequal, feebly expanding i>osteriorly 

 especially in the female, tiie disk plano-convex, separated by a well- 

 rounded but distinct shoulder from the vertical lateral lobes, brownish 

 fuscous, sometimes fiisco testaceous and then generally punctate with 

 ferruginous, the ni)per part of the lateial lobes with a broad i)i( eons 

 band crossing the prozona and sometimes continned as a feeble dusky 

 cloud on the metazona; front l)Oi-der truncate, hind border broadly 

 obtusangulate, the angle rounded; median carina distinct only on t,»e 

 metazona and at the front of the i)rozona. elsewhere obsolete or sub- 

 obsolete; prozona feebly longitudinal (male) or feel)ly transverse 

 (female), a very little longer than the minutely rugulose metazona. 

 Prosternal spine short, stout, blunt, conical, erect: interspace between 

 mesosternal lobes nearly half as long again as broad (male) or consid- 

 erablj' transverse but shorter than the lobes (female). Tegmina either 

 abbreviated, being one and a half to two and a half times as long as 

 the pronotum and not nearly reaching the tips of the hind femora, 

 tajjering considerably beyond the basal expansion, sublanceolate and 

 bluntly subacuminate {M.f. eiirtiis): or far surpassing the hind femora, 

 broad and subeiiual, very feebly tapering in the apical half and well 

 rounded at tip (.1/. /'. rolntieKSj Plate 1, tig. c), wholly brownish fuscous 

 or cinereo-fuscous, occasionally maculate to a greater or less degree, but 

 generally slightly in the discoidal area, the anal area sometimes mine 

 cinereous than the rest, especially apically ; wings in both forms hyaline 

 with a scarcely perceptible yellowish tint, more or less densely but 

 always feebly infumated at the ti^), the veins and cross veins of the 

 ai)ical half blackish fuscous. Hind femora relatively longer in the 

 female than in the male, dull luteo-testaceous, black at apex and at 

 extreme base and bifasciate with black or Idarkish fuscous more or less 

 broadly and obliquely, rarely transversely, the whole often confused 

 and more or less blended on the outer face; beneath pale or dull red- 

 dish; hind tibiae red, usually growing i)aler toward the base and some- 

 times almost wholly pale greenish luteous, feebly reddening api«-ally, 

 the base generally pale or at least paler, with a small fuscous patellar 

 spot, the spines black except at extreme base, nine to twelve, generally 

 eleven, in number in the outer seiie . Extremity of male abdomen 

 strongly clavate. well upturned, the supraanal plate long triangular 

 with well rounded acutangulate apex, the apical half depressed to a 

 slightly lower i)lane. with a broad, equal, deep, median sulcus, bounded 

 by high and sharp walls in a little more than the basal half: furcula 

 consisting of a i)air of minute, i)arallel. distant, tubercular teeth, twice 

 as long as broad, resting outside the ridges of ^he supraanal plate: 

 cerci simple, straight, and subeciual, being contracted a little in the
