Three specimens from the type-locality reared by G. G. Ainslie and 

 recorded under Webster No. 7599 A F, Bureau of Entomology, United 

 States Department of Agriculture. 



Family MYMARID.E. 



Subfamily GrOI<rA.TOCKRI]Sr^!K. 

 GONATOCERUS EXIMIUS, new species. 



Female. — Length 0.7 to 0.8 mm. In Girault's diagnostic table of 

 the species of this genus ^ this species runs to section II, but appar- 

 ently differs from both species included in that section in having the 

 ovipositor much longer, it being exserted at least three-fourths the 

 length of the abdomen and in some cases longer than the abdomen. 



Antennse 11-jointed, longer than the body; the scape extending 

 above the vertex, slightly swoUen below and toward the apex; pedicel 

 about as long as broad, much broader than the first funicle joint and 

 scarcely as long; joint 4 of the funicle slightly the longest of the 

 funicle joints; club solid and slightly longer than the two last 

 funicle joints combined. 



Head and thorax under high magnification with faint reticulate 

 sculpture; abdomen sessile, a little longer than the thorax, strongly 

 compressed from the sides for its whole length, viewed from the side 

 ovate; the ovipositor slender, strongly exserted, extending beyond 

 the apex of abdomen nearly or quite the length of the abdomen. 



Forewing oar-shaped, very slightly and uniformly infumated, the 

 venation ending at about the basal one-third of the wing; marginal 

 vein very slightly obliqued into the wing at apex; discal cilia moder- 

 ately coarse, and not arranged in definite rows; marginal cUia mod- 

 erately long, the longest about equal to half the greatest breadth of 

 the wings; longest marginal cilia of the hind wings at least four times 

 as long as the width of the wing, those on the anterior margin about 

 half as long as those on the posterior margin. Hind tarsi much 

 shorter than their tibiae, the basal tarsal joint about one and one-half 

 times the length of the second. 



Head, thorax, and abdomen black, the latter at base and extreme 

 apex pale testaceous. Antennae brownish black, the scape at base 

 and below more or less pallid; legs, including all coxae, pale brownish- 

 yellow, the femorae in some specimens dark brown medially; ovi- 

 positor sheaths black. 



Male unknown.
