and middle legs slender, short; hind legs robust, and also rather short. 

 Tegmina and wings considerably surpassing the apex of the abdomen, 

 the former of nearly equal width on basal two thirds or three- 

 fourths, their apex acuminate. 



Head large, robust, horizontal, somewhat broader than the front 

 edge of the pronotum, the occiput nearly or quite as long as the 

 pronotum, viewed laterally very gently arched; vertex horizontal, 

 acuminate, a little longer than wide, the sides straight, somewhat 

 laminate. Eyes small, not prominent, elongate pyriform, rather 

 widely separated above. Frontal costa prominent between the 

 antenna;, which are located opposite the upper third of the eyes, 

 deeply sulcate, suddenly constricted and lowered and again widening 

 in advance of the large ocellus, below this evanescent. Lateral 

 or facial carinas prominent, smooth, extending from near the outer 

 edge of the antennal pits to the base of the mandibles where they 

 unite with a transverse ridge which borders the lower face and forms 

 a walled area of the front. Antennae moderately robust, the basal 

 joints depressed, giving to these members a subensiform appearance. 

 Pronotum of moderate length, gently divergent behind, all three 

 transverse sulci continuous, more or less sinuouse and severing the in- 

 conspicuous median carina, the posterior lobe a trifle shorter than 

 the anterior lobe; anterior margin very broadly rounded, the hind 

 margin subangulate; lower lateral edges gently sinuose, the posterior 

 angle a right-angle, the immediate apex rounded. Tegmina slightly 

 coriaceous, moderately long, the apical third or fourth tapering, 

 the apex bluntly acuminate; wings transparent, delicate, a trifle 

 more than twice as long as broad. Hind femora moderately robust, 

 evenly tapering, two-thirds the length of the abdomen; tibiae also 

 robust, considerably shorter than the femora, seven- or eight-spined 

 externally, nine-spined internally. Abdomen moderately large, 

 tapering but little before the extreme apex; the valves of the 

 ovipositor and cerci all finger-like, hairy, the latter unarmed with 

 teeth or hardened apex for digging. Prosternal spine transverse, 

 the apex entire; mesosternal lobes subangulate within, the inter- 

 space at middle about one-third of the width of one of the lobes.
