SEEPHOID AND CHALCIDOID PARASITES OF THE HESSIAN ELY 97 



examined, the propodeum is without a neck, the funicle joints are 

 subquadrate, the sculpture is somewhat more shallow, and the ab- 

 domen has a broad black median stripe down the venter. 



Female. — Length 2.0 to 2.8 mm. Head transverse, distinctly broader than 

 the thorax, viewed from above fully three times as broad as long antero- 

 posterior^ at the middle, weakly convex in front, and distinctly but not deeply 

 concave behind, narrowing behind the eyes, the temples receding from the eye 

 margin and distinctly less than half as wide as the eyes ; ocelli in a very obtuse 

 triangle, the postocellar line very slightly longer than the ocellocular line, tha 

 latter more than three times as long as the diameter of an ocellus ; head viewed 

 from in front distinctly broader than high, about in proportion of 35 : 27 ; eyes 

 ovate, bare ; malar space equal to approximately half the eye height ; antennal 

 scrobe shallow ; clypeal margin nearly straight ; mandibles each with four 

 teeth ; maxillary palpi 4-jointed, labial palpi 3-jointed ; whole head closely 

 and nearly evenly punctate ; the clypeal region with fine converging striae. 

 Antennae inserted at the middle of the head, 11- jointed, slender, not thickened 

 toward apex ; scape slender, slightly curved, and reaching to the vertex ; pedicel 

 about twice as long as broad, very slightly shorter than the ring joints and the 

 first funicle joint together; two ring joints transverse, subequal; funicle 6- 

 jointed, the first to fifth joints subequal, each about twice as long as broad, 

 sixth joint usually a little shorter; club not thicker than funicle, very nearly 

 as long as the three preceding funicle joints together, solid, tapering to a sharp 

 point at apex but without an apical process. Thorax together with propodeum 

 nearly twice as long as broad at tegulae ; prothorax viewed from above 

 declivous, in a much lower plane than the mesoscutum, somewhat narrower 

 than mesothorax, and sculptured like the occiput ; mesoscutum convex, much 

 broader than long, the parapsidal grooves faintly indicated as shallow de- 

 pressions but not impressed as grooves ; scutellum convex, a little shorter than 

 the mesoscutum ; axillae broadly separated by base of scutellum ; propodeum 

 with a short but distinct neck, without a definite median carina and without 

 spiracular sulci, the lateral folds represented by a broad, shallow, immargined 

 depression on each side half way between the median line and the spiracle and 

 extending from the base of propodeum half way to the apex; spiracles small, 

 elliptical ; whole surface of mesoscutum, axillae, scutellum, and propodeum 

 closely punctate, the punctures on propodeum distinctly finer than those on 

 mesoscutum ; pleura sculptured like dorsum but with a smooth area beneath 

 the wings. Legs slender ; tarsi 5-jointed ; hind tibia with one spur ; hind 

 coxae outwardly sculptured like the pleura, on inner side nearly smooth. 

 Fore wings about twice as long as broad, extending beyond apex of abdomen, 

 bare at base for the whole length of submarginal vein, the discal cilia rather 

 weak, marginal cilia short; marginal, postmarginal, and stigmal veins in 

 approximately the proportions of 19 : 15 : 8. Abdomen broadly ovate, about 

 as long as head and thorax, broader than thorax and entirely smooth ; first 

 tergite comprising about one fourth the total length of abdomen, other tergites 

 subequal ; ovipositor barely showing at apex. 



Color of head and thorax dark metallic green ; abdomen pale yellow with 

 the first tergite basally bordered with brown or black ; mandibles testaceous, 

 brown at apex ; palpi pale ; antennal scape pale yellow at base, dark brown to 

 blackish on apical tw T o thirds ; pedicel dark brown ; funicle brownish at base, 

 usually becoming paler toward apex, the last funicle joint and the club usually 

 pale testaceous ; legs, except coxae, pale testaceous, the coxae concolorous with 

 the thorax ; wings hyaline, the venation pale yellowish. 



Male. — Length 1.2 to 2.3 mm. Antennae long and slender, 13-jointed, the 

 flagellum hairy; scape subcylindrical, thickest slightly beyond the middle; 

 pedicel as broad as long ; ring joints minute ; first funicle joint very nearly 

 four times as long as broad, fully two thirds as long as scape ; following joints 

 successively decreasing slightly in length and also very slightly in thickness, 

 the sixth funicle joint about three fourths the length of first; club narrower 

 than the funicle, distinctly 3-jointed, tapering to a point at apex, the joints 

 subequal in length or the first somewhat the longest, the three club joints 

 together about equal in length to the two preceding funicle joints together. 

 Abdomen elliptical, with a very short petiole, not longer or broader than 

 thorax. Antennae entirely dark brownish except base of scape, which is 

 testaceous; abdomen brownish testaceous. Otherwise like the female.
