no. 2068. NEW SPECIES OF INSECTS— GAHAN. 163 



Very similar to Eupteromalus nidulans Foerster, from which it dif- 

 fers principally as follows : Antennal flagellum black, the pedicel not 

 longer than the two ring-joints and the first joint of funicle combined; 

 apex of scutellum usually more faintly sculptured than the remainder 

 of the scutellum, often slightly shining with shallow reticulate punc- 

 tures, never with the three or four transverse rows of punctures at the 

 apex larger and deeper than the others; propodeal median carina 

 incomplete or wanting, never distinct and complete; stigmal vein 

 very nearly as long as the marginal. 



Male. — Similar to the female but with the antennal flagellum 

 brownish-yellow, the abdomen scarcely longer than broad, its first 

 segment wider at apex than the base of the second, segments beyond 

 the first together scarcely longer than the first. 



Type-locality. — Dodge City, Kansas. 



Host. — SarcopTiaga Jcellyi.

HABROCYTUS MEDICAGINIS, new species. 



Female. — Length about 1.7 mm. Head and thorax closely punc- 

 tate, the punctures on the medial portion of the mesoscutum slightly 

 larger than those on the scapulae and scutellum; antennae with two 

 ring-joints; pedicel and first funicle joint, excluding the ring-joints, 

 about equal; following funicle joints a little longer than the first 

 and a trifle longer than broad; viewed from in front the head is 

 broader than long, the clypeal region with converging striae and a 

 deep median sinus on the anterior margin; viewed from above the 

 head is slightly broader than the thorax, narrow antero-posteriorly, 

 the occiput slightly concave, the ocellocular line longer than the 

 lateral ocellar line, the lateral ocellar line not equal to half the 

 postocellar line ; pronotum strongly transverse with a sharp margin 

 anteriorly; propodeum short, without a neck, with a median carina 

 and lateral folds, the region between the lateral folds more or less 

 distinctly wrinkled and with a fovea-like depression at the base and 

 another at the apex of the fold; the region outside the lateral folds 

 is usually more faintly sculptured with indistinct lines; propodeal 

 spiracles elliptical; marginal and postmarginal veins subequal, the 

 stigmal one- third shorter; abdomen conic-ovate, about as long as 

 the head and thorax and nearly smooth, the dorsal segments beyond 

 the first with very faint transverse lines. Head and thorax aeneous; 

 antennae brown, the scape slightly paler beneath; wings hyaline; 

 all coxae aeneous like the thorax, all trochanters and femorae black 

 with an aeneous tinge; tibiae and tarsi usually reddish yellow, the
