flagellar joints above at apex each produced into a strong tooth 

 which on the middle joints is a little longer than the body of the 

 segment; tenth or apical joint nearly globose or a little broader than 

 long and apparently not divided. 



Forewing about two and one-half times as long as broad, bare at 

 base for a little more than half the length of submarginal vein, this 

 bare area prolonged along the posterior margin of wing about to 

 apex of submarginal vein; costal cell nearly uniformly ciliated; 

 ciliation on disk of wing rather dense; marginal cilia very short, 

 absent on apex of wing; stigmal vein about one-fourth as long as 

 marginal, postmarginal about half as long as marginal. 



Male. — Length 3 mm. Antennal scape very slightly swollen, ap- 

 proximately thrice as long as broad, pedicel a little broader than 

 long; first flagellar joint with a cone-shaped dorsal tooth, which is 

 about as long as the body of the segment, second to ninth flagellar 

 joints each with a much longer and distinctly compressed branch, 

 the ones on the fourth and fifth segments longest and about four or 

 five times as long as the one on the first segment; tenth joint without 

 a branch and about equal in length to the branch on the ninth seg- 

 ment. Clypeus and supraciypeal area transversely striated. Median 

 lobe of mesoscutum transversely rugoso-striate, the lateral lobes ir- 

 regularly rugose with little or no indication of striation; axillae 

 rugose; scutellum coarsely longitudinally striate; apex of scutellum 

 beneath the apical process more strongly rugoso-punctate than in 

 the female; propodeum coarsely rugoso-punctate; abdominal petiole 

 about one and one-half times as long as posterior coxa, not broader 

 at apex than at base and distinctly rugose. Otherwise like the 

 female,

The type of this species, as well as a series of 6 specimens from 

 Koiwai, Japan, and 60 specimens from Suigen, Chosen, including 

 numerous representatives of both sexes, has been examined. The 

 elongate and cylindrical flagellar joints in both sexes, the short and 

 bispinose scuteilar process, the very narrow costal cell, the very broad 

 and deep spiracular grooves on the propodeum, and a distinct hump
