NEW CHINESE XIPHIDIOPSIS — TINKHAM 519 



strongly hyperbolic or angularly rounded. Metazona not broader 

 than the prozona ; its length slightly less than the length of the pro- 

 zona. In profile metazona raised slightly above the plane of the 

 prozona. Lateral lobes of the pronotum slightly broader than deep. 

 Tegmina and wings extending considerably beyond the apices of the 

 caudal femora. Leg spination as follows : Forelegs with f orefemora 

 unarmed ; f oretibiae with four large pairs of spines beyond the tym- 

 pana and two small apical external spines ; tympana with both faces 

 apert. Middle legs with mesofemora unarmed; mesotibiae with four 

 large and two small apical external spines and two large subapical 

 spines and one small apical internal spine. Caudal femora unarmed ; 

 caudal tibiae not complete but probably closely similar in spination 

 to that of the allotype, description of which is to follow. Supraanal 

 plate entire, squai-ely truncate; cerci short and heavy at base with 

 the apical half gently incurved with internal apical surface exca- 

 vate. Tufts of tawny hairs clothe the internal basal half and the 

 apical region of the cercus. Subgenital plate rather large with long 

 truncate apex bearing long lateral, widely separated, subapical styli. 



Coloration. — Testaceous in preserved alcoholic specimens but fol- 

 iage green in life, with a few large infumate spots in a row in the 

 basal half and scattered roughly in two rov\s in the apical portions. 

 Pronotum with a band of brown occupying two-thirds of the dorsum 

 with the margins darker; the band somewhat constricted medianly. 

 Dorsum of head with the fastigial cone streaked with dark brown, 

 which divides into two narrow dark brown stripes crossing the occiput 

 and laterad with another dark brown stripe on each side extending 

 from the inner margin of the eye to the posterior margin of the occi- 

 put; these four stripes on the dorsum of the head quickly identify 

 this species. 



Allotype.— Fem-Al^, Shin Kai Si, Mount Omei, Szechwan, 4,400 

 feet, August 4-6, 1929 (D. C. Graham). Measurements in milli- 

 meters: Body length 9.5; length to apex of tegmen 22.0; length to 

 apex of wings 23.0; pronotum 3.8; tegmen 19.0 by 2.0; ovipositor 8.5. 

 U.S.N.M. No. 56298. 



Description. — Closely similar to the holotype in size and coloration. 

 Leg spination as follows: Forelegs with f orefemora unarmed; fore- 

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

 spines. Middle legs with mesofemora unarmed; mesotibiae with 

 five pairs of spines, the basal largest and an additional basal external 

 spine. Caudal femora unarmed ; caudal tibiae with 31-33 external and 

 32 or 33 internal short dorsal teeth, the distal ones largest and 8 or 

 9 external and four internal ventral spines. Ovipositor moderately 

 long, gently recurved apically. Subgenital plate quadrate, with 

 parallel and rolled lateral margins and convex posterior margin. 

 Sternite cephalad of the subgenital plate, rhomboid, with the posterior
