SCUDDER. — NORTH AMERICAN CEUTHOrHILI. 55 



hind femora externally marked heavily with fuscous in a scalariform 

 pattern, with a broad obscure castaueous annulatiou well before the 

 genicular lobes. The antenna! are slender and exceedingly long, 

 about four times as long as the body, and the legs are very long though 

 only moderately slender. Fore femora no stouter than the middle 

 femora, a little less than half as long as the hind femora, and rather 

 more (<$) or rather less (9) than three fourths as long again as tlie 

 pronotum, the inner carina with 2-3 spines. Middle femora with 

 similar spines on the front carina and on the hind carina a couple of 

 similar spines besides a not very long genicular spine. Hind femora 

 fully as long as the body, a little more than twice as long as the fore 

 femora, the basal portion stout and swollen but delicately tapering so 

 that nearly or in the female quite the apical third is subequal, and the 

 whole is four times as long as broad, the upper edge of the inner sur- 

 face with 4—5 distant raised points, the outer carina with about ten 

 sub-equal spines, the longest much shorter than the tibial spurs (c?)> 

 or with about six slight and distant recumbent spines (9), the inner 

 carina rather bluntly denticulate, distantly in the outer half (^) or 

 like the outer carina but more closely denticulate (9)' the intervening 

 sulcus narrow. Hind tibi;e barely arcuate at base ( (?) or straight ( 9 ), 

 a very little longer than the femora, armed beneath with 1-2 sub- 

 apical spines besides the apical pair ; spurs subopposite, the basal at 

 the end of the proximal third of the tibia, a little longer than the tibial 

 depth, set at an angle of about 60° with the tibia and divaricating 

 about 130° (($) or 150-170° (9), incurved at tip; inner middle cal- 

 caria a little longer than the outer, twice as long as the others or as 

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

 as long as the tibite, the first joint much shorter than the rest together, 

 the second nearly three times as long as the third and with it fully as 

 long as the fourth. Cerci slender, nearly half as long again as the 

 femoral breadth. Ovipositor three fifths as long as the hind femora, 

 straight, tapering and not very stout in the basal, slender and equal in 

 the apical half, the apex obliquely truncate, upturned, and acuminate 

 but not much produced, the teeth of the inner valves rather short 

 and aculeate.
