median line regularly half "herring-bone," dorsad of the line rather irregu- 

 larly scutellate proximad, passing to sul)shagreenous on distal section of 

 inflated portion of the femora: ventro-external margin of caudal femora with 

 three to four spines, ventro-internal margin of caudal femora with six to seven 

 spines. Caudal tibiae with median distal spurs longer than the dorsal or 

 ventral distal spurs, the internal median slightly longer than the external 

 median. Caudal tarsi damaged. 



General color between prout's brown and mummy brown, passing to sepia 

 on the genac, pleura and paler portions of the lateral lobes, the caudal femora 

 with a tawny-olive touch and the other femora with a faint dark olive wash. 

 Head with the occiput paling to snuff brown; eyes mottled prout's l^rown and 

 fuscous; antennae dresden brown proximad, passing to tawny, then distad 

 to dresden browai again. Pronotum with the dark shining sections of the 

 lateral lobes blackish fuscous; no whitish humeral line as usual in the genus. 

 Tegmina mars brown. Ovipositor becoming more chestnut-brown distad. 

 Femoral spines and areas at their bases blackish fuscous; spines of cephalic 

 and median tibiae with areas at their bases infuscate, the spines themselves 

 tawny with darkened tips. Caudal femora with median line of paginae black- 

 ish fuscous, this shading away ventrad, but sharply contrasted with the tawny- 

 olive wash of dorsal portion; caudal tibiae vermiculate with fuscous and 

 washed with russet. 



Length of body (exclusive of ovipositor), 37 mm.; length of pronotum, 12.3; 

 least width of pronotal disk, 5; greatest width of pronotal disk, 6.8; length of 

 exposed (lateral) portion of tegmen, 4.3; length of cephalic femur, 10.3; length 

 of median femur, 11.6; length of caudal femur, 3(5; greatest depth of caudal 

 femur, 6.1; length of ovipositor, 28. 



The type of tliis striking and most interesting species is uniqne.
