 less than half as long as the hind tibiae, the first joint almost equalling 

 the rest together, the second much more than twice as long as the 

 third and with it about as long as the fourth. Cerci rather stout and 

 short, hardly exceeding in length half the femoral breadth. Ovipositor 

 nearly straight and short, shorter than the fore femora, the basal half 

 tapering, the apical half slender and equal, the tip more than usually 

 upturned and produced to a very acuminate point, the teeth of the 

 inner valves long, aculeate, arcuate.

1 J, 2 9- Nebraska, A. Agassiz (Mus. Comp. Zool.). Thomas 

 reports it from several localities in Colorado, Wyoming, Dakota, and 

 Montana, but it is quite as likely as not that some other species was 

 mistaken for it. The one reported by Osborn and Bruner from Iowa 

 and Nebraska is the one here described as (7. bruneri. 



36. CEUTHOPHILUS OCCDLTUS, sp. nov. 



Body castaneous, more or less and irregularly blotched above with 

 feeble fuscous markings, most conspicuous on the pronotum and absent 

 from a narrow irregular and sometimes broken median stripe of the 

 ground color, which does not extend upon the abdomen ; abdomen 

 obscured with fuscous on the posterior margins of the segments. Legs 

 luteo-castaneous, the outside of the hind femora with the usual mark- 

 ings nearly obsolete. Antennae very long and slender, the legs 

 moderately long. Fore femora a little stouter than the middle femora, 

 about a sixth longer than the pronotum, and half or less than half as 

 long as the hind femora, the inner carina armed with a long preapical 

 spine and sometimes with another short one. Middle femora with a 

 long preapical spine on the front carina, sometimes accompanied in 

 the 9 by 1-2 others, the hind carina with a long genicular spine 

 accompanied by 2-3 spines in the $. Hind femora of about the 

 length of the body in the g, about twice (9) or distinctly more than 

 twice (^) as long as the fore femora, rather slender, being nearly 

 four times as long as broad, without conspicuous raised points on the 

 surface, the outer carina elevated, with 5-6 distant spinules, the largest 

 very small (,J) or not elevated, with many minute serrulations on the 

 apical half (9 ), the inner carina with numerous delicate spinules (<J) or 

 similar to the other carina (9). Hind tibice straight, distinctly longer
