Fiiacotestaceous, Havou.s beneatli. ITeiul rijivo testaceous, in fresh 

 specimens more or less fuscoolivaceous, much infuscated ab(>ve, with a 

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

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

 tinctly elevated above the lavel of the jn'onotum, the interai)a ;e between 

 the eyes twice (mule) or thrice (female) as broad as the tirst antenna! 

 joint; fastij»ium 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 eft'ected 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 ditference between the sexes, fully as long as (female) or distinctly 

 h)nger than (male) the intraocular portion of the genae; antenna«' 

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

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

 r. n. nebrascensis relatively longer).* Pronotum equal, except for beinj; 

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

 rounded subtectate, passing by a very broadly and uniforndy rounded 

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

 riorly feebly tumid vertical lateral lobes, which are more or less Havou.s 

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

 postocular band, 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 obtusangulate, 

 in the female often rotundato-obtusangulate; prozona distinclly longi- 

 tudinal in both sexes, sparsely and shallowly and sometimes very 

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

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

 interspace between mesosternal 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 pronotum, broad lanceolate, attingejit, 

 the costal margin angnlato-convex, the tip bluntly acuminate, ferrn 

 gineo-testaceous (P. n, nehrascensls), or surpassing a little the hiinl 

 femora, overlapping, rather broad, remarkably equal, the apex wt 11
