XIPHIDIOPSIS TRANSVERSA, new species 



Figure 157, o 



A medium-large species, known only in the female and quickly 

 recognized among the females of all the known species by the very 

 broad and transverse subgenital plate, with the eighth abdominal 

 sternite specialized and enlarged, triangular in form with the apex 

 directed cephalad. The species is not large enough to be the female 

 of X. ktrefchowensfs and in addition possesses dorsolatei-al stripes 

 on the pronotum. 



Holofype.—Femah, Shin Kai Si. Mount Omei, Szechwan, 4,500 

 feet (D. C. Graham). Measurements in millimeters: Body length 

 10.5; length to ovipositor tip 20.5; length to tegmen tij) approximately 

 25.0 (tip frayed); pronotum 4.0 by 2.0; tegmen approximately 21.5 

 by 2.8; caudal femur 11.6; ovipositor 9.7. U.S.N.M. No. 56301." 



Descripfior}.— Size fairly large and form typical of the genus. 

 Head slightly broader than deep; eyes subcircular and subglobular. 

 Fastigial cone prominent, with slight upward tilt. Pronotum with 

 foremargin very slightly convex; posterior margin somewhat cir- 

 cularly rounded ; lateral lobes much -broader than deep. Leg spi- 

 nation as follows : Foreleg with forefemur unarmed ; foretibiae with 

 five external and five internal infumate spines, of which the proximal 

 is small and dorsad of tympanum, the remainder much larger than 

 the external ones. Middle legs missing. Caudal femur unarmed; 

 caudal tibiae with 31 external and internal short black dorsal teeth 

 and 9 external and 3 internal apical small spines. Tegmina and wings 

 far surpassing apex of caudal femur. Ovipositor long and slender, 

 very slightly recurved, with apex considerably passing knee of caudal 

 femur. Subgenital plate very broad and transverse, lateral margins 

 strongly convex, posterior margin gently concave and slightly de- 

 flexed. Anterior margin fused to a short base making somewhat of 

 a T joint. Eighth abdominal sternite larger than remaining ab- 

 dominal sternites, triangular, with truncate posterior margin and 

 apex directed cephalad. 



Co7orafwn.~Fo\mge green in life, testaceous in death, with a slight 

 dorsolateral stripe of brown on the dorsum of the pronotum. 



The type is unique, and the species is named from the very broad and 

 transverse nature of the subgenital plate.
