258 HYMENOPTERA. 



clined to be darker, so at extreme tip. Venation pallid dusky. Fore 

 wings distinctly fumated especially distad (distal half of that portion 

 of the blade distad of the apex of the venation) ; posterior wings nearly 

 similarly fumated but the more distinct fumated area is still farther 

 distad. Eyes dark. Mandibles dark fuscous. Ovipositor yellowish. 



Abdomen sessile, as long as the head and thorax combined, conic- 

 ovate, the valves of the ovipositor exserted as stated, the exserted por- 

 tion subequal in length to the antennal club, clavate (broadening dis- 

 tad and somewhat paddle-shaped), appearing somewhat flattened 

 (depressed), nearly as long as the femora. Parapsidel furrows com- 

 plete, narrow, widely separated. Body bearing widely scattered, stiff 

 setae. Metathoracic spiracle minute, round. Body without marked 

 sculpture. Mandibles short, falcate, bluntly acute at apex. 



Fore wings oar-shaped, moderately narrow for the genus, graceful 

 for the genus, nearly uniformly ciliate discally (20 to 24 longitudinal 

 lines at the widest blade portion) , the discal ciliation moderately dense 

 (the longitudinal lines difficult to count), distinctly denser distad, 

 caudad bounded by a straight row of cilia running proximo-cephalad, 

 obliquely across the wing, to the base of the marginal vein where the 

 discal ciliation ends in a point. Marginal ciliation of the fore wing 

 moderately short and usual for the genus, the longest cilia not quite as 

 long as a fourth of the greatest wing width and distinctly not as long 

 as the longest marginal cilia of the posterior wing. Marginal vein 

 long and slender, distad leaving the costal margin, inclined obliquely. 

 Posterior wings narrow, only slightly wider across the apex of the vena- 

 tion than the average width of the blade, acute at apex, narrowing 

 gradually distad, without midlongitudinal discal ciliation but the two 

 paired lines of cilia along each edge present as usual in the genus, the 

 posterior paired line the more conspicuous ; its marginal vein clavate 

 slender, bearing a row of rather close-set, short setae (about 10) ; the mar- 

 ginal cilia moderately long, somewhat over twice longer than the blade 

 is wide at its middle ; posterior wings much shorter than the fore wings. 



Legs normal, tarsi 5-jointed, the proximal joint longest but not 

 long ; tibial spurs single, straight, short, rather stout, but those of the 

 cephalic legs longer, curved, forked at apex and forming the usual 

 strigil ; trochanters 2-jointed ; cephalic and posterior femora somewhat 

 thickened ; tibiae all slender, longer than the respective femora ; legs 

 clothed with stiff setae but not densely. 



Antennae 11-jointed, slender, the club slender, the flagellum filiform. 

 Scape long, cylindrical, slightly convexed ventrad, including the bulbs 

 equal to the club in length and as long as the pedicel and next two 

 joints taken together. Pedicel usual, slightly longer than the proxi- 

 mal funicle joint, as broad as the scape. Funicle peculiar by reason 

 of the fact that it bears joints alternately long and short ; the proximal 

 funicle joint is longer than wide but shortest, subequal however to 6; 

 joints 2 and 3 of the funicle are subequal, nearly a half longer, longest but
