rounded. Tegmiiia and Mings extending considerably beyond the 

 apices of the caudal femora. Leg spination as follows : Forelegs with 

 forefemora unarmed; foretibiae with four large pairs of spines and 

 one minute apical pair. Middle legs with mesofemora unarmed; 

 mesotibiae with four large and two minute apical external spines and 

 three large and two minute apical internal spines. Caudal femora 

 unarmed; caudal tibiae with 29-32 short black external and 26-29 

 black internal dorsal teeth and 9-11 external and 3 internal apical 

 small spines, Supraanal plate transverse and entire. Cerci short, 

 heavy in the basal two-thirds, with the apical third incurved; the 

 cerci bear a median dorsal finlike tooth that characterizes the species. 

 Subgenital plate of moderate size, longer than broad, with parallel 

 lateral margins and moderately convex posterior margin with two 

 small, lateral, widely spaced marginal styli. 



Coloration. — Uniformly foliage green in life, with a narrow lateral 

 brown stripe on the margins of the pronotum and a trace of a stripe 

 at the posterior angles of the eye not extending to the posterior margin 

 of the head. Fastigial cone with a pale brown dorsal stripe; rest of 

 head green. Dorsum of pronotum between the lateral stripes brown- 

 ish yellow. Tibial teeth of hindlegs black. 



Allotype.— Y^m^\Q, Si Gi Pin, Szechwan, 6,000-7,000 feet, August 8, 

 1929 (D. C. Graham). Measurements in millimeters: Body length 

 10.0 ; length to apex of ovipositor 17.0 ; length to wing tips 21.0 ; length 

 to tegmen tips 20.0: pronotum 3.0; hindfemora 10.0; ovipositor 6.8. 

 U.S.N.M. No. 56299. 



Description. — Closely similar to the holotype in size, form, and 

 coloration. Leg spination as follows: Forelegs with forefemora 

 unarmed; foretibiae with six external spines, the four basal the largest, 

 and four large internal and one \>\\\v of minute apical spines. Middle 

 legs with mesofemora unarmed; mesotibiae with six external and five 

 internal spines, the four basal the largest. Caudal femora unarmed ; 

 caudal tibiae with 25-28 external and 26-29 internal short black dorsal 

 teeth and 8 or 9 external and 3 or 4 internal pale ventral spines. Ovi- 

 positor moderately short, heavy, and moderately recurved apically. 

 Subgenital plate with moderately convex posterior margin and lateral 

 margins divergent to their broad base. Eighth abdominal sternite, 

 just cephalad of the subgenital plate with subparallel lateral margins, 

 the apex deeply notched by a right-angle incision as shown in figure 

 157, n. This character serves to readily distinguish X. gurneyi from 

 the known females of the Chinese species.
