scape, pedicel, and first two flagelhir Joints are browuish-yellow, the 

 first flagellar joint more than 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 fusc^ous, about 5 times as long 

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

 very short, narrower than the mesothorax and bch)W the dorsal line 

 depressed and produced into a sligiit neck. Mesothorax truncate be- 

 fore, with 3 coarsely punctate furrows. Scutellum with a punctate 

 frenum. Axillse separated from the scutcllum by about 8 imnctures. 

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

 teeth or spines. Wings fusco-hyaliu(^, darker beneath the stigma, the 

 stignial vein about twice as long as the stigma; both br.)wnish-black. 

 Legs dark rufous or reddish-brown, the coxai and femoi-a I lack, with 

 sometimes the tibia' bla<*k or dusky. Abdomen with course longitu- 

 dinal striie to near the apex of the second segment.

S 9. Length, 3.4 to 3.8""". Much like /».scf/><'Ai/j/.s', but may readily 

 be separated by the following differences: The $ antenuic 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 S the first flagellar joint is a little longer 

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

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

 the S the last joint of the palpi 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, Ya. 



Types in C<dl. 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 descrii)tion not being 

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

 above.
