reddish along the upper edge; posterior tarsi brown; abdomen black, 

 except the combined second and third segments, which are reddish 

 testaceous. 



Male. — Like the female in all essential characters. 



Type.—Csit. No. 25412, U.S.N.M. 



Type locality. — Syracuse, New York. 



Described from 12 female and 7 male specimens collected by C. J. 

 Drake on Rhus in early May. The color of the species varies some- 

 what from that of the type; some of the paratype specimens have 

 more or less reddish on the apical abdominal segments, and the anten- 

 nae of some females are almost wholly testaceous, while at least one 

 male has the antennae entirely black. The number of segments in 

 the antennae varies from 33 to 38 in both sexes, in the type series. 

 I have seen another series of 30 specimens, in the Cornell University 

 collection, taken at Montreal, Canada, in May, 1902. These average 

 a little smaller than the Syracuse specimens and the number of seg- 

 ments in the antennae is correspondingly reduced, varying from 

 31 to 34. 



16. METEORUS TEREBRATUS, new species. 



Distinguished especially by the unusually long ovipositor, which is 

 longer than the entire body. It differs further from Jiumilis, to which 

 it is related, by the much longer malar space, and the smooth pos- 

 terior coxae. 



Female. — Length 4.5 mm.; head transverse, but full behind the 

 eyes; face with distinct separate punctures, rather opaque, twice as 

 broad at base of clypeus as long; mandibles nearly as broad at base 

 as the greatest width of clypeus; malar space as long as basal width 

 of mandibles; antennae missing beyond first flagellar segment, which 

 is about as long as scape and pedicel united; ocelli very small, the 

 ocell-ocular line at least two and one-half times as long as greatest 

 diameter of an ocellus; vertex smooth and polished; temples broad, 

 polished; mesoscutum smooth and shining; the lobes well set off by 

 sharp parapsidal furrows; propodeum closely rugose, the longitudi- 

 nal and transverse carinae not well defined; the dorsal face accord- 

 ingly not distinctly areolated; propleura finely rugulose; mesopleura 

 mostly smooth with a rugulose area in the upper basal angle and a 

 longitudinal crenulate furrow below; metapleura wholly coarsely 

 rugoso-punctate; wings with stigma large, triangular; recurrent vein 

 entering first cubital cell near first intercubitus; first abscissa of 

 radius about half the second, the second at least half the length of 

 first intercubitus; radial cell large, extending nearly to apex of wing; 

 posterior coxae about as long as their trochanters, smooth and pol- 

 ished; posterior femora relatively smooth; inner spur of hind tibiae 

 less than one-fourth the length of the metatarsus; abdomen slender; 

 first tergite finely striate and provided with two fossae on the petiole
