290 HYMENOPTERA. 



joint for instance, not more than a fourth or fifth of the length of the 

 abdomen). Tarsi 4-jointed, the joints subequal, the proximal joint in 

 the cephalic legs, however, somewhat longer than the others of the 

 same tarsus. Strigil present on cephalic legs. 



Antennae normal for the genus, 9-jointed. Scape moderate in length, 

 as long as the next three joints combined. Pedicel usual, shorter than 

 second funicle joint, longer than the first. Proximal funicle joint sub- 

 quadrate, yet somewhat longer than wide, small, only a fourth the 

 length of the second funicle joint and a third that of the pedicel ; sec- 

 ond funicle joint longest of funicle, slender, a third longer than the 

 pedicel, a fourth longer than funicle joint 3, which is still slender but 

 yet slightly enlarged distad ; next three joints subequal in length, 

 broader, cylindrical ovate, each subequal in length to funicle joint 3, 

 each a little stouter than the one preceding but not very stout. Club 

 ovate, solid, slightly longer than the two joints preceding when com- 

 bined. Pubescence inconspicuous, consisting of sparse, scattered setae. 



From 9 specimens, -f-inch objective, 1-inch optic, Bausch 

 and Lomb. 



Male. — The same but somewhat shorter, abdomen shorter than the 

 thorax and bluntly triangular. The antennae are 13-jointed, filiform, 

 the proximal funicle joint shortest, longer than wide, subequal in 

 length to the pedicel, the other funicle joints about a fourth longer, 

 gradually lengthening somewhat distad and subequal in width ; the 

 distal funicle joint is twice the length of the proximal one and about a 

 fourth or more longer than the second funicle joint ; club joint conical, 

 slightly shorter than the distal funicle joint. 



From 1 specimen, the same objective and optic. 



Redescribed at first from one male and nine female speci- 

 mens captured on windows and by sweeping as follows : 

 One female taken on the window pane of a shed on a farm

 of the variety nigriventfis) taken together on the glass sides 

 of a greenhouse at Urbana, Illinois, April 30, 1910 ; one 

 male and three females taken together on a greenhouse win- 

 dow, Urbana, May 16, 1910 ; three females taken by sweep- 

 ing blue grass and clover at Urbana, June 8, 1910 ; and a 

 single female captured along the edges of a cypress swamp
