conical, feebly oppressed, slightly retrorse; interspace between meso- 

 sternal lobes half as long again as broad (male) or subquadrate (female), 

 the metasternal lobes attfngent (male) or approximate (female.) Teg- 

 inina abbreviate, overlapping, lanceolate, sharply pointed, longer than 

 the pronotum, fully twice as long as broad, their inner and costal mar- 

 gins about equally convex. Extremity of male abdomen a little clavate, 

 considerably recurved, bluntly conical, the supraanal plate triangular, 

 as long as broad, the sides nearly straight, the tip rounded; furcula 

 consisting of a pair of rather distant processes, broad at base, with a 

 slight tapering pointed projection, the whole very small; cerci very 

 tumid, sphcrico-triangular at base, carinate on the posterior outer 

 margin, with a slight, equal,- and blunt-tipped finger, shorter than the 

 base, extending inward and upward from the basal swelling; subgeni- 

 tal plate short, considerably broader at apex than long, because the 

 extreme posterior margin is produced to form a rather large rounded 

 elevation nearly as high as broad. 



The general color is a brownish griseous, tinged below with yellcw- 

 ish; the antennae are dark and sometimes darker apically; along the 

 top of the head and pronotum is a blackish fuscous rather broad 

 median stripe, sometimes broadening in patches, sometimes obsolete; 

 the upper half of the lateral lobes of the prozona is marked by a 

 broad blackish fuscous belt, which is often separated from the front 

 margin and the frequent extension of the band to the eyes by a nar- 

 row yellow line. The teginina are uniformly griseous, with a slender 

 median line of alternate yellowish and fuscous flecks, often obsolete. 

 The hind femora are lighter or darker testaceous, with two very broad, 

 oblique, blackish purple belts, which do not reach the pale orange 

 under surface; hind tibiae dull glaucous, the spines pale at base, black 

 tipped, ten to eleven, usually ten, in number in the outer series. Sides 

 of abdomen marked with black at base. 



Length of body, male, 22 mm., female, 30 mm. ; antennae, male, 9 mm., 

 female, 9.5 mm.; tegmiua, male and female, 7 mm.; hind femora, male, 

 12.5 mm., female, 14 mm. 



Seven males, 7 females. Between Lincoln, Nebraska, and Denver,

It is also reported from southwest Nebraska (Bruner). 



This species is very closely allied to the last, differing from it in its 

 narrower interspace between the sternal lobes, the oblique bands on 

 the outer face of the hind femora, the more distant forks of the furcula 

 of the male, and the stouter apical process of the subgeuital plate; 

 the cerci are much the same.
