narrower than the lobes in both sexes, the metasternal lobes approxi- 

 mate (male) or subapproximate (female). Tegmina distinctly (male) or 

 scarcely (female) shorter than the pronotum, lateral, rather widely sep- 

 arated, subovate with rotundato angulate costal margin and subacumi- 

 nate apex, brownish fuscous. Fore and middle femora no more tumid 

 in the male than in the female; hind femora ferrugineo testaceous, 

 faintly and angularly bifasciate with fuscous, the under surface fiavous, 

 the genicular arc broadly piceous; hind tibiae pale yellowish red, with 

 a fuscous patellar spot, the spines black almost to their base, ten to 

 eleven in number in the outer series. Extremity of male abdomen a 

 little clavate, slightly recurved, the supraanal plate triangular with 

 acutangulate apex, the surface strongly but broadly tectate, the median 

 sulcus broad, moderately deep, with very rounded walls, percurreut 

 but partially interrupted beyond the middle; furcula consisting of a 

 pair of rather slender, tapering and acuminate, parallel, approximate 

 fingers a little longer than the last dorsal segment, overlying the sub 

 median ridges of the supraanal plate; cerci small, simple, substyliform, 

 a little compressed, considerably shorter than the supraanal plate, 

 blunt- tipped or narrowly truncate; subgenital plate small, of about 

 equal length and breadth, the lateral and apical margins in the same 

 plane, entire, as seen from above strongly rounded, subangulate. 



Length of body, male, 17 mm., female, 18.5 mm.; antennae, male, 

 mm., female, 6.6 mm.; tegmina, male, 3.1 mm., female, 4.5 mm.; hind 

 femora, male, 9.5 mm., female, 10 mm. 



One male, 1 female. American Fork Canyon, Utah, A. S. Packard. 



This species is the nearest allied of the American forms to Podisma 

 pedestris of Europe, but differs distinctly from it in the structure of 

 the subgenital plate and the slender fore and middle femora of the 

 male.

Brownish fuscous above, often more or less ferruginous, sordid tes- 

 taceous beneath. Head fusco- or ferrugineo-olivaceous, more or 

 less infuscated above '(the infuscatiou sometimes confined to u pair of 

 widening streaks), with a broader or narrower piceous postocular band; 

 vertex gently tumid, scarcely or not elevated above the pronotum, the 

 interspace between the eyes twice (male) or nearly thrice (female) as 

 broad as the first antenna! joint; fastigium broad, moderately decli- 

 vent, scarcely sulcate; frontal costa rather prominent, fading before the 

 clypeus, equal, much narrower than the interspace between the eyes, 

 pi une, irregularly punctate; eyes of moderate size, slightly prominent 

 in the male, somewhat longer than the intraocular portion of the genae; 

 antennae dark castaneous, becoming blackish fuscous apically, nearly 

 three fifths (male) or hardly a half (female) as long as the hind femora.
