scape, i)edicel, and first two flagellar joints are browuish-yellow, the 

 first flagellar joint more tliiui twice as long- as the i)edicel; in S filiform ; 

 the scape is equal in length with the first flagellar joint, the following 

 joints slightly shorter, all black or dark fuscous, about 5 times as long 

 as thick; last joint of palpi one-half longer than the fourth. Prothorax 

 very short, narrower than the mesothorax and below the dorsal line 

 depressed and produced into a slight neck. jNIesothorax truncate be- 

 fore, with 3 coarsely i)un(*tate furrows. Scutellum with a punctate 

 frenum. Axilhe separateil from the scutellum by alxmt 8 punctures. 

 Metathorax armed in the middle, behind the scutellum, with two blunt 

 teeth or spines. Wings fusco-hyaline, darker beneath the stigma, the 

 stigmal vein about twice as long as the stigma; both brownish-black. 

 Legs dark rutbus or reddish-brown, the cox;e and femora black, with 

 sometimes the tibia* black or dusky. Abdomen with coarse longitu- 

 dinal stria? to near the apex of the second segment. 



Habitat. — Washington, D. C; Arlington, Ya; Manhattan, Kans., 

 and Wyoming.

$ $ . Length, 3.4 to 3.8""". Much like fiiscipoiii is, but may readily 

 be separated by the following ditterences: The 9 antenmc are usually 

 black, except sometimes the first two flagellar joints, which are pale 

 brownish, or at least beneath, the first flagellar joint being thrice as 

 long as the pedicel; in the 5 the first flagellar joint is a little longer 

 than the scape; while the axilhe are separated from the scutellum by 

 five large ijunctures, which is a constant character in both sexes. In 

 the (5 tlie last joint of the i)alpi is nearly twice as long as the fourth. 

 The legs in both species are variable in color, exhibiting more red in 

 some specimens than in others. 



Habitat. — Indiana and Arlington, Va. 



Types in Coll. Ashmead. 



Either one of these species could be used as typical of Say's species ; 

 but as Say's type is no longer in existence it devolves upon me to 

 designate which should be known as the type, his description not being 

 sufficiently definite to decide, and I have, therefore, separated them as 

 above.
