SCUDDER. NORTH AMERICAN CEUTHOPHILI. 57 



ing sulcus exceptionally broad. Hind tibise faintly and irregularly 

 sinuous (cJ) or straight (9), distinctly longer than the femora, slen- 

 der, armed beneath with 1-2 subapical spines besides the apical pair ; 

 spurs subopposite, the basal at or a little beyond the end of the proxi- 

 mal fourth of the tibia, a little longer than the tibial depth, set at an 

 ano-le of about 35° witli the tibia and divaricating 80°-'J0", the apical 

 half incurved; inner middle calcaria much longer than the outer, more 

 than twice as long as the others or as the spurs, but scarcely so long 

 as the first tarsal joint. Hind tarsi two fifths as long as the tibiae, the 

 first joint about as long as the rest together, the second nearly three 

 times as long as the third and with it fully as long as the fourth. 

 Cerc'i rather stout, shorter than the femoral breadth. Ovipositor only 

 slightly enlarged at base, the distal two thirds equal but not very 

 slender, straight, almost two thirds as long as the hind femora, the tip 

 considerably upcurved and finely acuminate, the teeth of the inner 

 valves triangular, increasing in length apically, only the terminal 

 arcuate. 



Length of body, $ 9 15.5 mm.; antenna?, 9 32+ mm.; pronotum,

 hind femora, $ 11. lb mm., 9 13 mm.; hind tibia?, $ 18.5 mm.,

1$, 39. Maryland (P. R. Uhler) ; Middle States (R. Osten 

 Sacken) ; Vigo Co., Ind., (W. S. Blatchley) ; Georgia. It is also 

 reported from New Jersey (Smith) and Tennessee (Brunner). Bru- 

 ner quotes it doubtfully among Nebraska Orthoptera, but I do not know 

 to what species he refers. 



Easily confounded with 0. hlatchleyi. 



21. Ceuthophilus blatchleyi. 



Ceuthophilus uhleri Blatchl.!, Proc. Ind. Acad. Sc, 1892, 1-44-145 

 (1894). 



In color and markings this species is indistinguishable from O. uhleri. 

 The legs and especially the hind femora are slenderer. Fore femora 

 no stouter than the hind femora, much less than half as long as the 

 fore femora, fully a third {$) or scarcely a fourth (9) as long again 

 as the pronotum, the inner carina with 2-3 spines, the subapical long. 

 Middle femora armed on the front carina much as in the fore legs, the 

 hind carina with a long genicular spine sometimes accompanied by 1-3 

 other spines, often minute. Hind femora nearly two and a half times 

 as long as the fore femora, longer than the body in both sexes, slenaer 

 and tapering, nearly the apical third subequal, three and a half times
