of discal ciliation proximad of it is about twice coarser than the main body 

 of the ciliation. Marginal and submarginal veins about equal, the post- 

 marginal vein absent, the stigmal distinct but not long. The caudal wing as 

 usual, its discal ciliation sparse, a distinct paired row along the cephalic 

 margin, the blade bluntly pointed. The posterior femora are swollen some- 

 what. Abdomen ovate. Tarsi 5-jointed. Scutellum not acute along its 

 caudal margin. 



Antennae 6-jointed, inserted near the mouth border — scape, pedicel, two 

 funicle joints and a long 2-jointed club. Scape long and slender, slightly 

 longer than the club, or the combined lengths of the pedicel, funicle and 

 proximal club joint ; pedicel moderate, obconic, distinctly longer than either 

 of the funicle joints but shorter than the proximal club joint ; funicle joints 

 not large but both longer than wide, oval, the second about a half larger than 

 the first ; proximal club joint long, widening distad, a third longer than the 

 pedicel, the distal joint twice the length of the pedicel and conic-oval ; club 

 long, cylindrical, tapering to a point distad. Antenns apparently without 

 pubescence. 



Male. — Unknown. 



Described from a single female specimen captured May 17, 1911, 

 on the windows of a small granary at Urbana, 111. (A. A. Girault). 



Habitat. — Illinois (Urbana). 



Type. — Type No. 14,122, United States National Museum, Wash- 

 ington, D. C, one female in xylol-balsam. This species is large, 

 beautifully and strikingly colored and should be easily recognized. 



TUMIDISCAPUS, new genus. 



.•\ genus allied to Paraphelinus Perkins in general shape of the wings and 

 body, but differing in having the scape of the antennae enormously enlarged, 

 bearing a leaflike expansion along its entire length and the antennal club is 

 shorter, less slender. Otherwise agreeing structurally with the genus named. 

 Type, the following species : 



Tumidiscapus flavus, new species. 



Male. — Length, 2.50 mm. Large for the subfamily. 



General color lemon yellow, the apical half of the abdomen tinged with 

 orange ; sides of abdomen darker ; appendages concolorous but distal tarsal 

 joint and apical joint of antennal club darker. Wings hyaline, venation yel- 

 low. Eyes dark red, ocelli ruby red. Tips of mandibles fuscous. 



Fore wings as in Aplieliiius Dalman but somewhat more slender ; marginal 

 vein slightly longer than submarginal, both long, the stigmal vein moderate in 

 length, straight, with a slight neck ; postmarginal vein absent. Discal ciliation 

 proximad of the oblique hairless line twice coarser and arranged in about five 

 lines; main discal ciliation fine; marginal cilia short on costal margin, about 

 as long as the proximal discal ciliation, noticeably longer (moderate in length )
