conical, feebly apjuessed, »li<j^litly retrorse; interspace between nieso- 

 sternal lobes halt" as long a};ain as bioail (male) or sulxiuadiate (female), 

 the metasternai lobes attin<^;ent (nnile) or apiiroximate (female.) Teg- 

 uiina abbreviate, overlai)pinj?, lan<'eolate, sbarpH' i)()inte(l, longer than 

 the iironotum, fully twice as long as broad, theii inner and costal mar- 

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

 considerably recurved, bluntly conical, the sui>raa!ial phite triangular, 

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

 consisting of a i)air of rather distant processes, broad at base, with a 

 slight tai)ering jHuntcd projection, the whole very small; cerci very 

 tumid, spherico triangnhir at base, carinate on the posterior outer 

 margin, with a slight, equal, and blunt-ti|>ped linger, shorter than the 

 base, extending inward and ui)ward from the basal swelling: subgeui- 

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

 extreme jjosterior maruin is i)roduced to form a rather large rounded 

 elevation nearly as iiigh as broad. 



The general color is a b.ownish griseous, tinged below with yellow- 

 ish; the ar.Lennae are dark and sometimes darker apically; along the 

 top of ihe 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 i)rozona is marked by a 

 broad blackish fuscous belt, which is often sei)arated from the front 

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

 row yellow line. The tegmina are uniforndy grise(ms, with a slender 

 uicilian line of alternate yellowish and fuscous tiecks, often obsolete. 

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

 oblique, blackish purj^'e 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 iu the outer series. Sides 

 of abdomen marked with black at base. 



Length of body, male, 22 mm., female, 20 mm.; antennae, male, 9 mm., 

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

 12.5 nun., female, 14 mm. 



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

 Cokuado. October 3; Lakin, Kear.iy County, Kansas, 3,009 feet, Sep- 

 tend)er 1; Colorado (C. V. (lillette); Colorado, 5,500 feet, Morrison ; 

 Pueblo, Colorado, 4.700 teet, August 30-31; Las Cruces, Donna Ana 

 County, New Mexico, T. D. A. Cockerell. 



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 subgenital plate; 

 the cerci are uuich the same.
