hind carina 1-2 spines besides the genicular spine. Hind femora 

 moderately stout, tapering regularly to the very tip with no pre- 

 genicular contraction, considerably more than twice as long as the fore 

 femora, less than three times as long as broad, glabrous, with no raised 

 points on any part, the outer carina pretty uniformly and finely serrate, 

 especially in apical half, the inner carina similarly but more sparsely 

 serrate, the intervening sulcus narrow except distally. Hind tibiae 

 straight in both sexes, slender, no wider in the middle than at base, 

 equal to or scarcely so long as the hind femora, armed beneath with 

 one or two preapical spines besides the apical pair ; spurs subopposite, 

 not so long as the tibial depth, set at an angle of about 45 with the 

 tibia and divaricating at even a less angle the extreme tips incurved ; 

 inner middle calcaria scarcely longer than the outer, nearly twice as 

 long as the others or as the spurs, and much shorter than the first joint 

 of the tarsi. Cerci rather stout, tapering, about two thirds as long as 

 the femoral breadth. Ovipositor rather stout and uniformly tapering 

 on the basal half, uniform and slender on the distal half, somewhat 

 longer than the fore femora, the extreme tip prolonged to a spine, the 

 teeth of the inner valves aciculate, arcuate. 



Length of body, $ 12mm., 9 13mm.; antennae, $ (est.) 30mm.; 

 pronotum, <J 3.75 mm., 9 3.6 mm.; fore femora, <J 4.2 mm., 9 4 

 mm. ; hind femora, 9 mm., 9 7.65 mm. ; hind tibiae, $ 8.5 mm., 

 9 7.65 mm.; ovipositor, 5 mm. 



4 <?, 1 9. Nevada, H. Edwards; North Pacific R. R. Survey 

 below Lake Jessie at Fort Benton, Dr. Suckley. Since description I 

 have received 2 <J, 5 9, from West Point, Lincoln, and Holt Co., 

 Nebraska, from L. Bruner ; and have seen in the Museum of Compara- 

 tive Zoology at Cambridge a $ and 9 from Santa Barbara, Cal. 

 (Osten Sacken), which apparently belong here, although there are no 

 indications of any transverse banding. There are also 2 in the 

 U. S. National Museum from California and Washington, both from 

 the Riley collection. 



This species is closely allied to C. californianus, but has slenderer 

 hind tibiae and a longer ovipositor ; its general appearance is very 

 similar, 



49. CEUTHOPHILUS TESTACEUS, sp. nov. 



Light fusco-testaceous, with a faint mediodorsal luteous stripe and 

 obscurely dotted with luteous (sometimes obsolete), the lower sides of 

 the body growing gradually pallid luteous, and the pronotum more or less 

 mottled or clouded with fuscous; legs testaceous, sometimes slightly
