170 ORTHOPTEROUS GROUP INSARAE 



flated, but little declivent to the fastigium, which latter is strongly bent 

 ventrad and almost subvertical, narrow, strongly compressed but not much 

 elevated, slightly narrowing distad, the apex bluntly and narrowly truncate, 

 in contact with the facial fastigium, entire length of the fastigium con- 

 siderably sulcate; eyes moderately prominent, elliptico-ovate, the greatest 

 width very slightly more than two-thirds the depth, the latter appreciably 

 greater than the same dimension of the infra-ocular portion of the genae; 

 antennae at least twice as long as the body. Pronotum sellate, the lateral 

 lobes appreciablj^ buUate ventrad, median section subconstricted, dorsal 

 line when seen from the side concave, regularly ascending caudad; disk with 

 the greatest caudal width contained almost twice in the length; cephalic 

 margin of disk gently arcuato-emarginate, caudal margin obtuse-angulate 

 with the immediate angle subtruncate, lateral portions of disk rounding 

 into the lobes, a weakly strumose condition present at the prozonal section 

 of the postocular bars; transverse sulcus forming a V-shaped figure mesad 

 on the disk, strongly impressed on the greater portion of the lateral lobes ; 

 lateral lobes with the greatest depth about two-thirds the greatest dorsal 

 length, cephalic margin sinuato-emarginate, ventro-cephalic angle ro- 

 tundato-rectangulate, ventral margin arcuato-emarginate cephalad, round- 

 ing into the ventro-caudal angle caudad, caudal margin moderately oblique 

 subarcuate, humeral sinus indicated only by a very broad and shallow 

 arcuate emargination. Tegmina about three-fourths the length of the pro- 

 notal disk, lobiform, overlapping mesad, ovoid, greatest width about two- 

 thirds of the greatest length, narrowing distad, apex rectangulate with the 

 immediate angle slightly produced; costal margin arcuate proximad, thence 

 oblique, but nearly straight, sinuate, sutural margin arcuate, venation 

 formed by the principal veins and transverse reticulations. Wings aborted, 

 not reaching the tips of the tegmina. Abdomen with the segments dis- 

 tinctly strumose at the lateral bars and less decidedly so medio-longi- 

 tudinally, the margins of the segments weakly and roundly produced at the 

 lateral bars and at the median dorsal bar; proximo-dorsal abdominal seg- 

 ment with no process; disto-dorsal segment subtruncate mesad; supra-anal 

 plate briefly tongue-shaped; cerci about twice the length of the supra-anal 

 plate, tapering, the tips blunted; ovipositor somewhat longer than the pro- 

 notal disk, the greatest depth contained slightly more than twice in the 

 length, arcuate, apical section bhmtly acuminate, margins and disk armed 

 as in other species of the genus; subgenital plate trigonal, with a distinct 

 medio-longitudinal sulcus bordered laterad by parallel rounded ridges. 

 Limbs but moderately elongate; femora with the dorsal genicular sections 

 not spinif orm produced ; genicular lobes of the cephalic and median femora 

 bispinose, of caudal femora more or less distinctly unispinose. Cephalic 

 femora slightly more than twice the length of the pronotal disk. Median 

 femora with their length surpassing that of the cephalic femora by about 

 the tegminal length. Caudal femora robust for the genus, considerably 

 inflated in the proximal half, their length nearly twice that of the median 

 femora: caudal tibiae surpassing the femora by slightly more than the teg- 

 minal length.
