NEW CHINESE XIPHIDIOPSIS — TINKHAM 521 



life: tympanal areas of foretibiae piceous. The dark color of the 

 dorsum of the head caiidad oiP the fastigial cone and the darkened 

 tympanal areas serve inmiediately to separate this species from others. 

 Median area of tegmina with a few scattered infiimate spots and 

 stridiilating field and anal margin areas reddish tinged where the 

 margins are attingent; wings slightly infumate. 



Allotype. — Female, Tseo Jia Geo, south of Suifu, Szechwan, 1,400- 

 2.000 feet (D. C. Graham). Measurements in millimeters: Body 

 length 8.5; length to tip of tegmina 20.0; length to wing tips 21.5; 

 length to tip of ovipositor 14.0: pronotum 3.5; tegmina 17.5 by 1.8; 

 ovij)osit<)r 5.0 nmi. The hindfemora are missing in the allotvpe. 

 U.S.N.M. No. 56297. 



Description. — Similar in form, size, and coloration to the holotype. 

 Leg spination as follows: Forelegs with forefemora unarmed; fore- 

 tibiae with four large pairs of spines and one external apical small 

 spine. Middle legs with mesofemora unarmed ; mesotibiae with five 

 external and four internal large spines. Hindlegs missing in allotype 

 and female paratype but probably similar to the spination in the 

 holotype. Ovipositor short, moderately stout, and moderately re- 

 curved in the apical half. Subgenital plate large and roundly 

 triangular. 



Paratype. — One female, Kuanshien, Szechwan, August 1-4, 1934 

 (D. C. Graham; U.S.N.M.). Measurements in millimeters: Body 

 length 9.0; length to tip ovipositor 14.0; length to wing tips 21.5; 

 length to tegminal tips 20.5; tegmina 17.0; pronotum 3.4; ovipositor 

 5.0. Hindfemora missing. Deposited in the Tinkham collection. 

 Paratype identical to the allotype. 



XIPHIDIOPSIS GURNEYI, new species 



Figure 1o7, l-n 



A small species recognized by the squarely truncate and entire 

 supraanal plate, by the short simple incurved cerci bearing a median 

 dorsal fin. and by the diacritical bipronged eighth abdominal sternite 

 lying just cephalad of the large and somewhat rounded subgenital 

 plate. The male appears to be most nearly related to X. capricercus 

 Tinkham. 



Holotype. — Male, Mount Omei, Baian-Kara-Ula Eange, Szechwan, 

 altitude 4.500 feet, July 26, 1929 (D. C. Graham). Measurements 

 in millimeters: Body length 10.0: length to cercus tip 11.5: length 

 to tip of tegmina 17.5: length to wing tips 19.0: pronotum 3.2 by 2.3; 

 hindfemora 8.0. Deposited in the Hebard collection in Philadelphia. 



Description. — Size small and form typical of genus. Head not 

 much broader than deep, eyes subcircular and subglobular. Pronotum 

 with foremargin gently convex; posterior margin hyperbolically
