NEW CHINESE XIPHIDIOPSIS — TINKHAM 515 



pronotiim 3.8 ; length to wing tips 25.5 ; tegmina 17.0 by 1.5 ; hindfemora 

 12.7. Holotyi^e in the Hebard collection in Philadelphia. 



Description.— K moderately large-sized species of slender build and 

 yellowish coloration. Head narrow, its breadth less than depth. Eyes 

 large, circular, and strongly subgiobular, separated by a breadth one 

 and one-half times an eye diameter. Fastigial cone very small and 

 narrow projecting forward from between the antennal foveolae. 

 Pronotum long and rather narrow, the metazone only a shade broader 

 than the prozona ; posterior margin broadly elliptical. Lateral lobes 

 slightly deeper than the breadth of the prozona. Tegmina long and 

 narrow, margins slightly subparallel, gently converging toward the 

 apex. " Wings projecting about 5 mm. beyond the apex of the tegmina. 

 Leg spination as follows : Forelegs with femora unarmed, f oretibiae 

 with 9 external and 7 internal spines, the proximal 6 largest and un- 

 paired, the apical ones minute and paired. Middle legs with femora 

 unarmed; mesotibiae Avith 7 external and 8 internal small spines. 

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

 internal yellow teeth on the dorsal keels and 10 or 11 external and 

 3 or 4 internal apical spines on the ventral keels. Supraanal plate 

 enormously produced into two broad, dorsoventrally flattened, fur- 

 culalike processes, separated by a space slightly less than the breadth 

 of one of the processes; this cleft or space continuing to the very 

 base of the plate. The apices of the supraanal processes are slightly 

 deflexed and bear a conspicuous inward-projecting tooth. The cerci 

 lie below and are shorter than the supraanal processes and in lateral 

 profile appear somewhat spatulate, with the apical portions strongly 

 incurved and bearing at their inferior apical angle a long upturned 

 spine. Subgenital plate very small, roughly triangular with a pair of 

 apical styli. 



Coloration. — The nonalcoholic preserved type has a decided yel- 

 lowish-brown cast, the caudal tibiae being definitely yellowish brown 

 although the natural color may be greenish or yellowish. The dorsum 

 of the head is dark reddish brown, this band continuing on the dorsum 

 of the pronotum with only very slight broadening on the metazona; 

 the band is parallel-sided on the prozona. Cells of the tegmina pale 

 purplish brown, with the veins contrastingly pale. Wings partially 

 infumate with purplish brown. Internal surface of basal antennal 

 segment and fastigial cone piceous; remainder of the antennae very 

 dark reddish brown. Eyes purplish brown or pale kidney brown. 

 Remainder of the body, other than the dorsum of head and pronotum 

 and the antennae, uniformly pale yellowish brown. 



Allotype. — Female, same data as for the holotype. Measurements 

 in millimeters: Body length 12.0; length to tip of tegmina 22.0; 

 length to wing tips 28.0; length to tip of ovipositor 22.0; tegmina
