SCUDDER. — NORTH AMERICAN CEUTHOPHILI. 47 



fully twice as long as the body, the legs moderately short. Fore femora 

 not stouter thau the middle pair, a third longer than the pronotuni and 

 distinctly less thau half as long as the hiud femora, the inner carina 

 with a long preapical spine sometimes accompanied by a shorter one. 

 Middle femora with 1-2 spines on the front carina besides a preapical 

 spine, and on the hind carina usually two spines besides the genicular 

 spine. Hind femora somewhat shorter than the body, considerably 

 more than twice as long as the fore femora, less than three times as 

 long as broad, the swollen portion pretty stout, hardly more thau the 

 distal sixth of equal width, with a few feebly raised points on the 

 upper apical portion of the inner side only, the outer carina delicately 

 uniformly and densely serrate throughout ( J* ) or with a few apical 

 obscure serrations (9)5 ^^^ inner carina similar. Hind tibiae straight 

 in both sexes, rather stout in the male, scarcely exceeding the femora 

 in length, armed beneath with a preapical spine besides the apical pair ; 

 spurs subopposite, the basal beyond the end of the proximal third of 

 the tibia, hardly or no longer than the tibial depth, set at an angle 

 of 45° with the tibia and divaricating 90-100°, their tips incurved; 

 inner middle calcaria somewhat longer than the outer, twice as long as 

 the others or as the spurs, but not so long as the first tarsal joint. 

 Hind tarsi two fifths the length of the tibiae, the first joint nearly as 

 long as the rest together, the second twice as long as the third and with 

 it longer than the fourth. Cerci rather slender throughout, tapering, 

 pointed, as long as the femoral breadth. Ovipositor less than three 

 fifths as long as the hind femora, gently tapering in the proximal half, 

 equal and not very slender in the distal half, the tip upturned a little 

 and pointed at an angle of 45°, the teeth of the inner valves sharjD but 

 not aculeate.
