I'R,OU EASTERN CI{INA.

Dannuli. Ovipositor with shield black, the elongate slendervalves light yellow.
Holotype, 9, Kiangsu, September(Kor,ruonr).
I name this interesting species after its discoverer. By
Epw.c.nps'key to the Old \{'orld. speciesof the subgenus(1.c.,(9) 8: 70-781; 1921), the fly runs to couplet 37, where itdisagrees with all species beyond by the black abdomen,inconjunction with the lack of cell Jll, of the wings. The species is well-distinguishetlfrom other regionat atlieJ by the black
bod.y and abruptly bright yellow head.
