NEW CHINESE XIPHIDIOPSIS — TINKHAM 513 



genicular areas, and the small apical teeth on the ventral valvulae of 

 the ovipositor will serve to distinguish the female from all other 

 Chinese species. 



Holotype. — Male, Kwanhsien, Szechwan, western China, July 12, 

 1930 (Hebard collection). Measurements in millimeters: Body 

 lengtli 12.0 ; length to tip of wings 26.0 ; pronotum 5.4 by 3.0 ; hind- 

 femora 12.5. The type is deposited in the Hebard collection at the 

 Academy of Natural Sciences of Philadelphia. 



Description. — General form typical of the genus. Head about as 

 broad as deep ; eyes circular and subglobular. Vertex about one and 

 three-quarters times the diameter of an ej^e. Fastigium with a small 

 laterally compressed narrow cone, buttressed on each side by the 

 flanged and raised inner margins of the antennal f oveolae. Pronotum 

 narrow on the prozona, considerably elevated and expanded on the 

 metazona ; the dorsum of the metazona slightly convex with traces of 

 the lateral carinae; front of the metazona marked by a transverse 

 sulcus. Seen in profile the plane of the prozona is considerably de- 

 pressed below that of the metazona. Posterior margin of the prono- 

 tum broadly elliptical in outline. Lateral lobes slightly greater than 

 the breadth of the prozona. Tegmina long and narrow, surpassing the 

 apices of the caudal femora by tvv-o-thirds their length. Costal mar- 

 gin of the tegmina considerably expanded in the basal half; tympanal 

 vein strongly developed. Wings very slightly longer than the teg- 

 mina. Leg spination as follows : Forelegs with f orefemora unarmed 

 and 6 external and 5 internal spines on the ventral margins of the fore- 

 tibiae. Middle legs with mesofemora unarmed ; mesotibiae with 6 

 external and 5 internal ventral spines. Caudal femora unarmed; 

 caudal tibiae with 26-28 external and 28-32 internal teeth on the dor- 

 sal keels and 9-10 external and 3 internal apical spines on the ventral 

 keels. Supraanal plate with tvro widely spaced short caudally pro- 

 jecting prongs. Cerci strongly cylindrical in the basal half ; apical 

 half sharply recurved with the upper margin flanged and elevated with 

 the basal portion acutely produced proximally. Inner margin of 

 apical half of cerci strongly flanged into an inward projecting plate. 

 Subgenital plate narrow and deep, the apical portion lying normally 

 between the bent arms of the cerci. 



Coloration. General body color in life probably green, in the pre- 

 served specimen yellowish brown. Dorsum of head and pronotum 

 dark reddish brov/n, paling on the posterior half of the metazona. 

 Lateral margins of pronotum edged with piceous, these margins di- 

 verging from the prozona into the metazona; the area immediately 

 below the dark margins whitish. Tympanal vein area of tegmen 

 somewhat darkened. Genicular areas of the caudal femora and ex-
