little longer than the outer, the shortest not exceeding in length the 

 tibial depth, the proximal more recumbent than the distal and there- 

 fore set at an angle with the tibia varying from 40 to 75, divaricat- 

 ing 20 30, the whole faintly incurved ; inner middle calcaria of $ 

 scarcely longer than the others or than the distal spurs and much 

 shorter than the first tarsal joint; calcaria of 9 subequal but decreasing 

 in length from above downward, those of opposite sides subequal, the 

 longest no longer than the shortest tibial spurs and much shorter than 

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

 the first and fourth joints subequal, and either nearly twice as long as 

 the second and third, which again are subequal, and all but the last 

 apically produced beneath in the 9 to a spinous point. Cerci slender, 

 tapering regularly, about three fourths as long as the femoral breadth. 

 Ovipositor short, hardly as long as the fore femora, straight, broad 

 even at apex, the extreme upper tip of which is feebly produced ; teeth 

 of inner valves aculeate, arcuate. 



Length of body, $ 15 mm., 916 mm. ; pronotum, $ 5 mm., 9 4.5 

 mm. ; fore femora, $ 5 mm., 9 5.25 mm. ; hind femora, $ 12.5 mm., 

 9 11.25 mm.; hind tibiae, $ 10.5 mm., 9 8.5mm.; ovipositor, 5 mm.

PHRIXOCNEMIS VALIDUS, sp. nov. 



Nearly uniform testaceous, glabrous, with feeble infuscation in 

 clouds upon the sides of the pronotum, and to a scarcely perceptible 

 degree upon the whole dorsum, made more evident by a fine medio- 

 dorsal luteous thread down the whole body, the legs of the body color, 

 but the apical half of the femora more or less though at most feebly 

 infuscated and the hind femora tipped narrowly with fuscous ; the 

 hind femora have also a faint rufous tinge. The antennae are moder- 

 ately stout and probably at least three times as long as the body, and 

 the legs short and stout, the vertex rudely bituberculate. Fore femora 

 distinctly stouter than the middle femora, a sixth longer only than the 

 pronotum and half as long as the hind femora, the inner carina fur- 

 nished with a row of minutest denticles but with no subapical spine. 

 Middle femora with three subequal spines on the front carina, the hind 

 carina unarmed and apparently with no genicular spine. Hind femora 

 very much shorter than the body, twice as long as the fore femora, 

 very stout, being not over two and a half times longer than broad, 

 with only two or three raised points on the inner edge of the upper 

 surface beyond the middle, the outer and inner carina? similarly armed
