434 GEOLOGICAL SURVEY OF THE TERRITORIES. 



it. This is the only instance I recollect to have met with an individual 

 of this genus in any of the Territories, and possibly I may have been 

 mistaken here, but I think I was not. 



L0CUSTID.5]. 

 Stenopelmatini. 



Stenopehnatus fasciatus^ nov. sp. 



Pale testaceous. Head tawny ; feet pale ; abdomen marked with 

 alternate rings of black and white. 



Head slightly broader than the thorax ; occiput evenly roimded and 

 smooth. Pronotum transverse, slightly excavated in front; sides nearly 

 parallel; posterior lateral angles obtusely rounded; posterior margin 

 nearly straight; a transverse furrow near the anterior margin, and an 

 oblique indentation each side of the faint median line near the middle. 

 JMeso- and meta-thorax constricted. Abdomen inllated, as broad or 

 broader than the head, about twice the length of the thorax. Cerci of 

 the male short, slender, and hairy ; superanal plate triangular, tumid, 

 emarginate. Ovipositor very short, not longer than the cerci of the 

 male, conical and turned up at the apex. Anterior tibiiB two-spined 

 beneath, with a third small spine immediately above the circlet on the 

 imwer margin; middle tibia3 with two spines on the outer margin, one on 

 the inner, and a small one in the n^iddle near the base; posterior tibiae 

 in the female have five inner and three outer spines, in the male five 

 inner and four outer. Both sexes apterous. 



Color, (alter immersion in alcohol, but varying very slightly from the 

 living specimens:) 



Female. — Mandibles black; face yellow; head brownish or tawny; 

 pronotum tawny, fading to light yellow; legs, venter, and sternum pale 

 yellow ; spines tipped with piceous. Each abdominal segment has a 

 broad ring or band of black on the anterior or middle portion, and a 

 narrow band of pale yellow on tlie posterior margin; sometimes the lat- 

 ter extends across the suture upon the margin of the next segment. 



Male. — Mandibles tipped with black ; labrum fuscous; head and thorax 

 paler than in the female ; apex of the tibiiB dusky. Dark bands of the 

 abdomen grow narrower on the apical segments. 



Dimensions. — 9^^, length, 1.23 inches; posterior femora, .38 inch; 

 posterior tibioe, .37 inch. 1 have a specimen from Texas, a female, 

 which measures 1.G5 inches in length, but the above measurements 

 give the average of the western specimens. 



Hahifaf. — Wyoming, Utah, Southern Idaho, and Texas. Eare, never 

 lacing found in great nimibers at any point. 



This species, though not exactly agreeing with Group II of Walker, 

 (Gat. Dermap. Salt., Supp. to pt. I, p. 107,) is closely allied to his /S\ 

 £onatus. 



Paphidophorinl 



Ceiitliophilus palliduSj nov. s]). 



Pale testaceous ; with four strong spines on each superior margin of 

 the posterior tibite. 



Female. — Second joint of,the antenufle enlarged at the apex ; anterior 

 femora with two (sometimes three) spines beneath, near the ai>ex, the 

 one next the apex being much the largest ; middle femora with one or 

 two spines beneath, and one on the in*side of the apex; posterior fe- 

 mora unarmed ; the four anterior tibite generally have two spines in
