Dor- 



cuate transversely, the greatest 

 length equal to the caudal width ; 

 cephalic margin subtruncate, 

 caudal margin very broadly 

 obtuse-angulate, lateral angles 

 rounded ; lateral lobes very con- 

 siderably longer than deep, the 

 ventral margin truncate-arcuate 

 both angles rounded. Tegmina 

 very slightly shorter than the 

 apex of the abdomen; medias- 

 tine vein with about eleven 

 branches, lateral field with the 

 margin moderately arcuate dis- 

 tad. Ovipositor slightly more 

 than half the length of the body, 

 slender, with a hardly perceptible 

 arcuation, valves finely serrate; 

 styles slender, slightly exceeding 

 the tip of the ovipositor ; subgen- ^ 

 ital plate distad with a broad, shallow sul^trigonal 

 emargination. Cephalic femora distinctly longer 

 than the pronotum, moderately inflated ; cephalic 

 tibiae equal to the femora in length, very slightly and 

 gradually tapering, the tympanum perforate cau- 

 dad. Median limbs missing. Caudal femora very 

 slightly shorter than the tegmina, considerably in- 

 flated, the genicular region small and with the lobes 

 narrowly rounded; caudal tibiae about four-fifths 

 the length of the femora, dorsal margins spinulose 

 proximad, spinulose and spinose distad, the spines five in number on 

 each margin, the spurs on the internal margin much longer than those 

 of the external margins; caudal tarsi with the proximal joint nearly 

 equal to the remaining joints in length, the distal joint but slightly 

 shorter than the proximal. 



General color cinnamon, the pronotum somewhat inclined toward 

 umber; eyes vandyke brown; mouth-parts and antennas pale; abdomen 

 mummy brown; styles and ovipositor vandyke brown.
