iiuiToNver tlinii the lobes in both Rexe«, the nietasteriial lobes approxi 

 mate (nialo) or siihapproxiinate (female). Teg^inina distinctly (male) oi 

 scarcely (reinalc) shorter than the pronotuTii, lateral, rather widely sep 

 arated, subovate with rotundato aiij^Milate costal margin and subacumi 

 nate apex, brownish fuscous. Fore and middle femora no more tunn'd 

 in the male than in the female; hind femora ferrnj^ineo testac^eous, 

 faintly and an;;nlarly bifasciate with fuscous, the under surfa(;e tlavons, 

 the j;t'nicular arc broadly piceous; hind tibiae ])ale yellowish red, with 

 a fuscous j)atcllar spot, the spines black almosr to their base, ten to 

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

 little clavate, slightly recurved, the supraanal plate triangular with 

 aeutangulate ai)ex, the surfa* e strongly but broadly tectate, the median 

 sulcus broad, moderaiely deep, with very rounded walls, ])ercurr<'nr 

 but partially interrupted beyond the middle; fureula consisting of ii 

 l)air of rather slender, tajjering and acuminate, parallel, approximate 

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

 median ridges of the supraanal plate; eerci small, f^irajjle, substyliform. 

 a little compressed, considerably shorter than the supraanal plate, 

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

 e<iual length and breadth, the lateral and a[)ical margins in the same 

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

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



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

 pcdeati'lii of Europe, but differs distinctly from it in the structure of 

 the sul)genital plate and the slender fore and middle femora of the 

 male.

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

 broad as the first antennal Joint; fastigium broad, moderately dedi 

 vent, scarcely sulcate; frontal costa rather ])rominent, fading before the 

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

 l)lane, irregularly punctate; eyes of moderate size, slightly prominent 

 in the male, somewhat longer than the infraocular portion of the geiia*';
