shorttM- in tho foinalo, tho lobes moderately tuniid in their cephalic por- 

 tion, particularly of the prozona, the caudal margin descending 

 obliquely cephalail, the ventral margin slightly emarginate cephalad. 

 Prosternal spine thick, somewhat compressed in the male, directed 

 caudad; interspace between the mesosternal lobes half again as long 

 as broad in the male, slightly longer than broad in the female; meta- 

 sternal lobes contiguous in the male, subcontiguous in the female. 

 Tegmina in the male subovate, reaching nearly to the distal margin 

 of the proximal abdominal segment and slightly shorter than the pro- 

 notum; in the female suborbicular, reaching to about the middle of the 

 same segment and distinctly shorter than the pronotum, the apical 

 margin slightly subangulate in the male, broadly subtruncate in the 

 female, the greatest breadth of the tegmina in the male about two- 

 thirtls the length, in the female slightly less than the Jength. Abdomen 

 moderately compressed, the apex in the male slightly expanded and 

 erected but not recurved ; fm-cula developed as short, well separated 

 spines, not longer than the segment from which they arise and slightly 

 diverging distad ; supra-anal plate trigonal, the median sulcus narrow 

 and extending about two-thirds the length of the plate; cerci with the 

 length not more than twice that of the broad base, 

 from which the remainder of the cercus is sharply c— ^~ .

 ately compressed, the apex slightly rounded ventro- apex of male 

 dorsad. Cephalic and median limbs robust in the abdomen, (x 

 male. Caudal femora well developed but not strongly 

 inflated, in the male vcr}' slightly exceeding the head, pronotum and 

 tegmina in length, in the female distinctly exceeding these; caudal 

 tibife with ten to eleven spines on the lateral margins. 



General color clay color. Head with the vertex and occiput marked 

 with a median longitudinal bar of seal brown, more or less broken into 

 spots; postocular bar blackish-brown; face and genre clouded and 

 washed with drab, rather greenish-oli^'e in the male; e,yes russet; 

 antennae flame-scarlet, a little oljscured distad and less brilliant in 

 general color in the male (nearly vermilion) than in the female. Pro- 

 notum olive dorsad in the male, of the general color with a median 

 wash of prout's brown on the prozona in the female; lateral lobes with
