58 HYMENOPTERA. 



nearly en echelon ; the group of discal cilia in the distal third of the 

 wing contains about 12 lines; fore wings slightly infuscated through- 

 out but not uniformly. Antennae 7-jointed, the joints as in the male ; 

 pubescence sparse, the setae moderately long and soft, most numerous 

 on the club. Scape slender, cylindrical, subequal to the club in 

 length ; pedicel obconic, distinctly longer than the funicle, subequal 

 in length to the intermediate club joint or longer and nearly as wide ; 

 ring-joint abruptly smaller, nearly as wide at its base, however, as the 

 base of the funicle joint which is longer than wide and oval in shape, 

 the smallest antennal joint excepting the ring-joint and the proximal 

 club joint; the latter subequal to the funicle in length, hemispherical, 

 wider than long and about a third shorter than the intermediate club 

 joint, which is subquadrate and slightly longer than the conical termi- 

 nal joint; the latter bears at its apex two long spine-like setae which 

 are not as long as the distal club joint ; they adhere closely and often 

 appear as one. Club ovate, forming the larger of the two halves of 

 the fiagellum. 



What is known further concerning this species may be 

 found in Girault (1909). I have since captured the following 

 specimens : Six females July 8, 1910 and 3 9 's July 27, 

 1910 from the sides of a greenhouse on the campus of the 

 University of Illinois, Urbana.

Normal position. 



Female. — Length, 0.55 mm. ; moderately small. General color uni- 

 formly deep blood red or sanguineous*: Antennae, legs including 

 the coxaet, shoulders and a portion of the venter of the mesothorax, 

 dusky, in life the antennae dusky and pallid alternately, the legs pallid 

 marked with blackish ; trochanters, articulations of the legs and an- 

 tennae and the proximal two tarsal joints, the occiput, genae and facet, 

 pallid; apical joints of the tarsi deeper dusky. Venation pallid. 

 Fore wings hyaline with the exception of a conspicuous rounded dusky 

 or sooty spot|| under or caudad of the stigmal vein and a very slight 

 cloudy streak across the wing in the same place, a faded continuation 



* In balsam the color fades to a beautiful pink or else becomes car- 

 mine. 



t Excepting the brown-black cephalic coxae in one specimen, 



t In two specimens the genae ventrad of the eyes across the clypeus 

 were brown-black. 



II This spot is considerably faded in some specimens.
