264 HYMENOPTERA. 



fact like brunneus tenuipennis, primarily in having the fourth funicle 

 joint over half as long (two-thirds as long) as the fifth (twice longer 

 than wide), much longer than the third, not so in either americanus 

 or anthononii (nor brunneus) where the fourth funicle joint is not more 

 than half as long as the fifth and distinctly not over twice longer than 

 wide ; it differs from tenuipennis as can be inferred from what has 

 been stated by having the somewhat broader fore wings, and in an- 

 tennal structures, tetiinpennis having the fourth funicle joint short, no 

 longer than the third or but very slightly longer and only about half 

 as long as the fifth funicle joint. Otherwise it is the same as brunneus 

 tenuipennis. Antennal scape and pedicel, however, somewhat more 

 yellowish than the dusky olive-green fiagellum. 



Antennae 11-jointed ; first two funicle joints subequal, longer than 

 wide, but not very much so ; funicle 3 longer by a fourth, one and 

 one-half times longer than wide, funicle 4 still longer, twice longer 

 than either 1 or 2, subequal in length to pedicel, slightly over twice 

 longer than wide, very slightly enlarged ; funicle 5 about a third longer, 

 stouter, longest joint of the funicle; 6 and 7 subequal, slightly wider 

 and shorter ; 8 slightly wider, shorter than 7, slightly longer than 4. 

 Scape slender. Proximal tarsal joints moderately long.

Male. — Unknown. 



Described from three female specimens in balsam, captured 

 by sweeping miscellaneous vegetation, Urbana, Illinois, July 

 27, 1910, and at Du Bois, Illinois, June 23, 1910. 



Habitat. — United States : Urbana, Du Bois, Illinois. 



Type. — Accession No. 44,215, Illinois State Laboratory of 

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

 (on a slide with Polynemcs and other mymarids) ; type locality, 

 Urbana, Illinois. 

 5. Goiiatocerus maxiimis species nova. 



Normal position. 



Female — Length, 1.35 mm. Large for the genus. 



Similar in general to dolichocerus Ashmead but agreeing also with 

 nigritarsis Ashmead by reason of antennal structures but falling in 

 between these two species. It agrees more with the former especially 

 in coloration and in the shape of the fore and posterior wings, but the 

 proximal three funicle joints of the antennae are shorter, agreeing in 

 this respect nearly with nigritarsis . Coloration like that of dolicho- 

 cerus ; fore and posterior wings similar to those of that species, the 

 marginal vein similar ; antennae differing in having the first and second 

 funicle joints about equal, each distinctly shorter than the pedicel,
