disk of the fastigium with the impressed line of essentially the same 

 form as the margin of the fastigium, the apex of the impressed line 

 being nearer to a line drawn between the cephalic margins of the eyes 

 than to the apex of the fastigium; angle of the fastigium when seen 

 from the side rectangulate, the facial line vertical to between the 

 antennas where the face becomes considerably retreating; lateral 

 foveolae elongate-lanceolate, the ventral margin not strongly marked; 

 frontal costa regularly but very slightly expanding caudad, considerably 

 sulcate ventrad of the ocellus, slightly so dorsad; eyes trigonal-ovoid, 

 in length about equal to the intraocular sulcus, when seen from the 

 dorsum not very prominent; antennae about four-fifths the length of 

 the caudal femora, slightly ensiform proximad. Pronotum with the 

 disk slightly less than one and one-half times as long as the greatest 

 caudal width of the same; cephalic margin subtrun- 

 cate, caudal margin very slightly arcuato-angulate ; 

 median carina not prominent but distinct; lateral 

 carinae but little constricted mesad, moderately 

 divergent caudad, the width between the same 

 cephalad being two-thirds of that caudad; principal 

 transverse sulcus placed distinctly caudad of the 

 middle. Tegmina less than three times as long as 

 the disk of the pronotum, failing to cover the ab- 

 domen by nearly the pronotal length, the tegmina 

 considerably narrowed distad, the apices narrowly 

 rounded. Interspace between the mesosternal lobes 

 decidedly shallow and transverse, the width being 

 equal to that of one of the lobes ; interspace between 

 the metasternal lobes small, subquadrate. Caudal 

 femora reaching to but not surpassing the apex of the abdomen, slender, 

 but more robust than usual in the genus, the greatest width contained 

 about four times in the length, pattern of the paginae well impressed, 

 internal genicular lobes slightly acute, external obtuse-angulate > 

 caudal tibiae slightly arcuate proximad, spines numbering from eleven 

 to thirteen. 



General color ochraceous-buff , becoming ochraceous on the abdomen, 

 hoary-white on the sides of the head, dark clay color on the dorsum 

 of the head and pronotum and french gray distad on the tegmina. 

 The usual broad postocular bar is mars brown, the longitudinal line 

 on the external face of the caudal tibiae is vandyke brown and un- 

 broken. The lateral carinae of the pronotum are ochraceous-buff, 

 marked mesad with very dark brown on the metazona, with the same
