Type: 9 ; Alta Mira, Tamaulipas, Mexico. June 27, 1903. (M. E. 

 Hoag.) Acad. Nat. Sci. Phila. 



This new species is quite distinct from any of the previously known 

 species in the genus, and can readily be distinguished by its large size, 

 very long and powerful posterior limbs and comparatively short ovi- 

 positor. 



Size very large; form elongate-fusiform. Head with the fastigium 

 about as wide as the length of the eye, bluntly rounded, touching the 

 facial process; eye ovate, comparatively small and not prominent; 

 antennse slightly exceeding the body and ovipositor in length, basal 

 joint flattened inferiorly. Pronotum slightly expanding posteriorly, 

 decidedly prolonged; slightly flattened on the disk, but lateral angles 

 rounded; anterior margin truncate, posterior margin broadly rounded, 

 no carina present; lateral lobes longer than high, the posterior margin 

 slightly emarginate, the inferior margin oblique, the angles obtuse. 

 Prosternum with two suberect slender spines; mesosternum and 

 metasterniun acutely lobate. Tegmina or wings not apparent. 

 Abdomen moderately compressed, each segment with a slight 

 thickening of the posterior margin on the median line, on the 

 distal segments supplemented by additional like structures, which 

 are arranged in longitudinal series. Ovipositor slightly curved, 

 short, but slightly longer than the pronotum and not more than 

 half the length of the posterior femora, subequal in width ; the apex 

 very acute, with superior margin straight for a short distance; 

 subgenital plate subtruncate apically. Anterior cox» strongly spined ; 

 femora about equal to the pronotum in length, two or three spines on 

 the anterior margin, unarmed on the posterior margin; tibiiE slightly 

 longer than the femora, bearing three spines on the posterior superior 

 margin. Median coxse unarmed; femora slightly longer than the 

 anterior femora, margins unarmed except for the short paired spines on 

 the genicular lobes; tibia slightly longer than the femora, anterior 

 superior margin with two spines, posterior superior margin with four 

 spines, one of which is apical. Posterior femora ec^ual to the body in 

 length, strongly inflated l^asally, slender apically, internal inferior 

 margin spined except apically; tibise about equal to the femora, sub- 

 quadrate, the superior margins closely and evenly spined. 



General color prout's brown, marked on the dorsum with vandykc 

 brown and on the lower portion of the lateral lobes and the pleura with 

 wood-brown. Head with the facial portion and the gense suffused 

 with bistre, a faint postocular streak present; antennae narrowly annu-
