Fu'sco-testaceous, flavous beneath. Head navo-testaceous, in fresh 

 specimens more or less fusco-olivaceous, much infuscated above, with a 

 broad piceous postocular band, and often with a pair of divergent fus- 

 cous or ferrugineous stripes on the summit: vertex very tumid, dis- 

 tinctly elevated above* the level of the pronotum, the interspace between 

 the eyes twice (male) or thrice (female) as broad as the first antenual 

 joint j fastigiuin rather rapidly declivent, with scarcely perceptible sul- 

 cation ; frontal costa not nearly reaching the clypeus, much broader 

 below than above the ocellus, the change rather abruptly effected and 

 more striking in the female than in the male, at its broadest consider- 

 ably narrower than the interspace between the eyes, distinctly impressed 

 at the ocellus, and in the male sulcate below it, punctate throughout, 

 above biseriately; eyes moderately large, rather prominent, with no 

 great difference between the sexes, fully as long as (female) or distinctly 

 longer than (male) the infraocular portion of the geuae; antennae 

 testaceous, feebly infuscated apically, about four-fifths (male) or three- 

 fifths (female) as long as the hind femora (but in southern examples of 

 P. n. nebrascensis relatively longer). Pronotum equal, except for being 

 faintly subsellate, especially in the male, the disk ferrugineo-fuscous, 

 rounded subtectate, passing by a very broadly and uniformly rounded 

 shoulder, forming a semblance of blunt lateral carinae, into the ante- 

 riorly feebly tumid vertical lateral lobes, which are more or less tiavous 

 below, and above are marked on the prozona with a very broad piceous 

 postocular baud, generally broader on the posterior section and occa- 

 sionally broken there; median carina sharp but not high, equal, per- 

 current; front margin subtruncate, hind margin very obtusaugulate, 

 in the female often rotundato-obtusaugulate; prozona distinctly longi- 

 tudinal in both sexes, sparsely and shallowly and sometimes very 

 obscurely punctate, nearly half as long again as the densely and finely 

 punctate metazona. Prosternal spine rather long, erect, conical, blunt; 

 interspace between mesosterual lobes about two and a half times longer 

 than broad (male) or about half as long again as broad (female). Teg- 

 mina slightly longer than the prouotum, broad lanceolate, attingent, 

 the costal margin angulato-convex, the tip bluntly acuminate, ferru 

 gineo-testaceous (P. n. nebrascensis}, or surpassing a little the hind 

 femora, overlapping, rather broad, remarkably equal, the apex well
