Fore wings shaped as in longipes but the blade is less petiolate, 

 widening farther proxiniad and broader, the discal ciliation distinctly 

 coarser and long, at the widest blade portion arranged in about twelve 

 longitudinal lines, the marginal diliation as in longipes but coarser 

 and not quite so long in relation to the greatest wing width, though 

 distinctly longer than the greatest wing width. Posterior wings as in 

 loftgipes but shorter ; very narrow and straight. Legs as in longipes ; 

 also other body characters. Ovipositor not exserted. Vertexal carina 

 present. 



Antennae 9-jointed. Scape as long as the pedicel and first two funi- 

 cle joints combined ; pedicel globular-obconic, longer than the proxi- 

 mal funicle joint, slightly shorter than the second funicle joint ; the 

 latter longest of the funicle joints, only moderately long, widening 

 slightly distad, over twice the length of the short proximal funicle joint 

 which is not much longer than wide. The third joint is about a third 

 shorter than the second. Joints 4 and 5 shorter and broader, sub- 

 equal, but 5 slightly shorter, about a third shorter than 3; joint 6 of 

 the funicle somewhat longer than either of the two preceding joints 

 but not as long as joint 3, broader than joints 4 or 5. Club abruptly 

 very large, ovate, as long as the combined lengths of joints 2, 3 and 4 

 of the funicle. Pubescence sparse; the club minutely hispid.

Male. — Unknown. 



Described from a single female specimen taken on green- 

 house windows at Urbana, Illinois, July 27, 1910. 



Habitat. — United States : Urbana, Illinois. 



Type. — Accession No. 44,248, Illinois State Laboratory of 

 Natural History, Urbana, Illinois, one female in xylol-bal- 

 sam. Colypes. —C2it. No. 13,819, United States National Mu- 

 seum, Washington, D. C. (two females in xylol-balsam, 1 

 slide ; with a specimen of P. lo?igipes and a Gonatocerus) . 



This species more closely resembles caesariatipennehecOinse 

 of the somewat long, somewhat hair-like discal cilia of the 

 fore wings, but otherwise they are distinct and may be dis- 

 tinguished by aid of the table of species given beyond. In 

 this species, however, the discal cilia are more like those of 

 maailipes, those of longipes being the nearest to normal cilia- 

 tion, nearly normal in fact. The species caesariatipe7ine has 

 this ciliation unusually long, like hairs. 



I have since seen two other females of this species mounted .i^'"
