REHN AND HEBARD 53 



pressed, subequal, with an appreciable mcdio-longitudinal sulcus on the 

 dorsal surface, lateral margins roundly elevated, fastigium in contact with 

 frontal fastigium for the full width of both; eyes large, prominent, ovate" 

 in outline, slightly less in length than the infra-ocular portion of the genae. 

 Pronotum with dorsal length about one and four-tenths the greatest (caudal) 

 dorsal width; dorsum of pronotum very slightly depressed within the mar- 

 gins; lateral carinae of dorsum of pronotum gently concavo-divergent in 

 the cephalic third, then as gently arcuato-divergent caudad without a dis- 

 tinct angulation; cephalic margin of dorsum of pronotom straight, caudal 

 margin of same arcuate, lightly emarginate mesad; lateral lobes of pro- 

 notum with length subequal to depth, the ventro-cephalic angle obtusely 

 rounded, the ventro-csiudal angle rather broadly rounded, the caudal margin 

 arcuate, the humeral sinus deep, roundly acute-angulate. Tegmina long 

 and narrow, the distal width greater than themesal width, the tegmina reach 

 beyond the distal extremities of the caudal femora and are obliquely trun- 

 cate at the apex with the angles very narrowly rounded; marginal field of 

 tegmina narrowing evenly distad from point of greatest width which is proxi- 

 mad. Disto-dorsal segment of abdomen with greater part of surface occu- 

 pied by a subdepressed area, hexagonal in shape; supra-anal plate rather 

 long, broadly trigonal, with lateral margins somewhat convex; cerci short, 

 straight, crassate, tapering to a blunt apex, the apex toothed, this tooth di- 

 rected at an angle meso-dorsad; subgenital plate short, lateral margins con- 

 vergent distad, distal extremity sinuato-truncate, bearing laterad short 

 slender articulate styles, cephalad from the base of the styles extend slightly 

 divergent rounded elevations which become obsolete about the middle of the 

 plate. Cephalic and median limbs slender, the cephalic and median femora 

 carinate dorso-distad for a very short distance with distal margin of same 

 bluntly rectangulate, genicular lobes spiniform; cephalic tibiae with proxi- 

 mal extremity much swollen, narrowing sharply below the tympanum, 

 median tibiae slightly expanded proximad. Caudal femora shorter than 

 the tegmina by more than the greatest pronotal length, the proximal half 

 moderately buUate, genicular lobes decidedlv acute-angulate produced 

 with the immediate apex narrowly rounded. 



A female, bearing the same data as the male here described, furnishes the 

 additional information given below. 



Description of Female.— Yavy much like male in size and general appear- 

 ance. Ovipositor nearly equal to cephalic femur in length, broad, sharply 

 bent at the base, the bent portion of dorsal margin and distal half of ventral 

 margin finely serrate; subgenital plate elongate-lanceolate with immediate 

 apex very narrowly rectangulate emarginate, in transverse section this 

 plate is narrowly U-shaped and embraces the base of the ovii:)ositor.
