Figure 157, d 



This small braclivpterous species is distinguished from the two 

 known brachypterous Chinese species, X. hastaticercus Tinkham, 1936, 

 and X. fmnuhiJi Tinkham, 1941, by its slightly larger size, much heavier 

 build, and much broader ovipositor. In addition the ovipositor is 

 less noticeably recurved than in those two species and the smaller teg- 

 mina are barely exposed from under the pronotum. 



Holoti/p<\ — Female, near Yachow, Szechwan. western China, eleva- 

 tion 3,200-3,500 feet, August 29, 1930 (D. C. Graham) . Measurements 

 in millimeters: Body length 9.0; length to tip of ovipositor 14.0; pro- 

 notum 3.4: lateral length of tegmina 0.8; hindfemora 7.5 by 1.75; 

 ovipositor 5.6 by 1.0. The unique type is U. S. N. M. No. 56293. 



Description. — Size small, form of heavy build. Head broader than

 with a small bluntly conical prominence separating the large an- 

 tennal scrobes. Pronotum not expanded on the metazona but of uni- 

 form breadth throughout, its length about two and one-half times 

 its breadth. Dorsum of the pronotum flat with a shallow V-shaped 

 suture just cephalad of center; dorsum angularly roimded into the 

 shallow lateral lobes. Tegmina small, ovoid, its truncate rounded 

 posterior margin only partly exposed from under t;he gently convex 

 posterior margin of the pronotum. Leg spination as follows: Fore-
