nearly straight, apex distinctl}^ oblique truncate, the immediate apex 

 narrowly rounded; mediastine vein strong, nearl}' straight; anterior 

 ulnar vein sinuate, after bending ventrad from the posterior ulnar 

 vein it recurves and continues closely parallel to the same; intercalary 

 area broad and filled with a network of irregularly meshlike nervures. 

 Wings elongate, narrow, apex rounded acute-angulate; discoidal vein 

 with two rami, the proximal diverging before the middle, the distal 

 separating near the distal third, the proximal furcate; ulnar field 

 occupied by a closely placed scalariform pattern of parallel transverse 

 veins numbering about forty-five, those in the narrow proximal section 

 being very closely placed, while the distal section is occupied by the 

 regular vein pattern; anal vein distinctly sinuate a short distance 

 distad of the middle ; anterior axillary field narrow, veined much as the 

 ulnar field and bent under the inflated posterior axillary field, the 

 latter broad, with a scalariform pattern of about thirty veins, as a rule 

 more spaced than in the ulnar field, the vein bounding this area caudad 

 being very much thickened and slightly arcuate. Abdomen sub- 

 cylindrical, subgenital plate conical, somewhat compressed, slightly 

 carinate ventrad; cerci small, styliform, the apex slightly bent ventrad; 

 supra-anal plate slightly compressed, the median depression sub- 

 fusiform with margins high, apex acute. Prosternal spine strongly 

 compressed, blunt, directed slightly cephalad; interspace between the 

 mesosternal lobes distinctly longitudinal, narrower than one of the 

 lobes; interspace between the metasternal lobes much smaller, sub- 

 quadrate; the whole of the sternal region slightly but distinctly concave. 

 Cephalic and median limbs very short, robust; caudal femora slightly 

 more than half the length of the tegmina, thick and with the pre- 

 genicular constriction but little marked, greatest width contained 

 nearly five times in the length, carinse low and hardly marked, paging 

 with the pattern very slightly sculptured and with little resemblance 

 to the typical Acridoid chevrons; caudal tibiae very slightly shorter 

 than the femora, very slightly sinuate, lateral margins with ten spines 

 one of which is apical, internal margins with eleven spines, internal 

 spurs moderately long, subequal, the whole of the dorsal surface of the 

 tibise clothed with long white pile ; caudal tarsi quite elongate. 



General color mummy brown, mingled and sometimes contrasted 

 with wood brown. Head wood brown laterad , washed with russet dorsad 

 and with a narrow median bluish line, face of the general color, eyes 

 burnt umber; antennae dragon's blood red proximad, brick red distad. 

 Pronotum with the margin of the crest and portions of the ventral 

 section of the lateral lobes touched with bistre. Tegmina with four
