ternal bases of caudal tibiae very dark reddish brown. Eyes pur- 

 plish gray. Antennae testaceous with widely spaced darkened joints. 



Allotype. — Female, Kwanhsien, Szechwan, elevation 4,000 feet, Oc- 

 tober 13, 1934 (D. C. Graham). Measurements in millimeters: Body 

 length, 15.0; length to tip of wings, 31.0; length to apex of ovipos- 

 itor, 26.0; pronotum, 4.8; tegmina, 25.5; ovipositor, 11.0. U.S.N.M. 

 No. 56295. 



Description. — Size slightly larger than the holotype; head closely 

 similar. Pronotum with the prozona broader than in the holotype, 

 the constriction between the breadth of the prozona and metazona less 

 than in the holotype; dorsal plane of metazona flatter and less ele- 

 vated above that of the prozona than in type. Tegmina similar to type 

 but costal margin and tegminal veins less developed. Fore and middle 

 legs similar to the type. Caudal femora unarmed ; caudal tibiae with 

 22-23 external and 24-26 internal teeth on the dorsal keels and 9-11 

 external and 3 internal small apical ventral spines. Ovipositor of- 

 moderate length and very slightly recurved. Ventral valvulae with 

 1 large and 6 minute subapical teeth; this feature separating this 

 species in the female sex from all other females of the Chinese species. 

 Subgenital plate broad with the posterior margin rounded and bear- 

 ing a shallow median concavity. 



G oloration. — Closely similar to the holotype but somewhat bleached 

 by preservative fluid. 



Paratypes. — One female. Mount Omei, Szechwan, altitude 4,500 

 feet, July 28, 1929 (D. C. Graham; Hebard collection). One female. 

 Mount Omei, 4,400 feet, July 13, 1931 (D. C. Graham; Hebard collec- 

 tion). One female. Shin Kai Si, Mount Omei, 4,400 feet, August 4-6, 

 1929 (D. C. Graham; U.S.N.M.). One female, near Mupin, China, 

 Szechwan, 2,000-2,800 feet, July, 1929 (D. C. Graham; U.S.N.M.). 

 Kange in measurements in millimeters: Body length 14.0-15.0; pro- 

 notum 4.5-4.8; tegmina 24.5-25.5; hind femora 14.5-15.0; ovipositor 

 10.5-11.5. Paratypes similar to the allotype in coloration and feat- 

 ures, and deposited in the United States National Museum, Hebard 

 and Tinkham collections. 



XIPHIDIOPSIS MEGAFURCULA, new species 



Figure 157, <i, s 



A moderately large, fully winged species distinguished from all 

 other Chinese males of the genus by the very long, separated, dorso- 

 ventrally flattened, furculalike processes of the supraanal plate and 

 in the female by the long, narrowly triangular subgenital plate, the 

 apex of which bears a minute triangular notch. 



Holotype. — Male, Maan Chi Shan, Kwangtung, South China, X- 

 XII, 1921 (C. W. Howard). Measurements in millimeters: Body 

 length 14.0 to apex of supraanal process ; length to tip of tegmina 20.5 ;
