[Jan., 



laterad; supra-anal plate broadly tongue-shaped; ovipositor about 

 twice the length of the disk of the pronotum, moderately 

 robust and arcuate, tapering in proximal two-thirds, dorsal 

 margin very considerably and regularly arcuate to the very apex, 

 ventral margin very faintly arcuate except for the distal fourth 

 which forms a quadrant, dorsal margin with seven to eight distal 

 teeth, increasing in length distad, ventral margin with nine to ten 

 distal teeth increasing in length distad and with the apical ones 



somewhat recurved ; sub- 

 genital plate almost divided 

 in two (chitinous portion 

 completely divided) , lateral 

 sections elongate acute, the 

 tips aciculate, slightly 

 curved toward the median 

 line of the body. Cephalic 

 femora about one and two- 

 thirds times the length of 

 the head and pronotum to- 

 gether. Median femora slightly longer than the cephalic femora. 

 Caudal femora about two and one-half times the length of the 

 cephalic femora. 



Paratypic Series. — We have selected as paratypic eight males: two 

 from canyon behind PuUiam Bluff (locality of Type) and the re- 

 mainder from Moss Well (locality of Allotype).
