448 PROCEEDINGS OF THE NATIONAL MUSEUM vol.88 



Male. — Length 2.3 mm. Agreeing with the description of the male 

 of mireoviridU except that the scutellum is somewhat less strongly 

 sculptured, the axillae and scapulae are also more uniformly finely 

 alveolate, the abdominal petiole is nearly three times as long as hind 

 coxa, the antennal scape and the pedicel are dark metallic, and all of 

 the femora are metallic with their apices narrowly testaceous. The 

 supraclypeal area is usually a little longer than broad as in the 

 female. 



Type locality. — ^Ridgway, Colo. 



ry;?e.— U.S.N.M. No. 53554. 



Described from 16 females and 7 males collected in the type locality 

 by E. H. Beamer, July 1, 1937. The holotype, allotype, and 10 

 paratypes are retained in the U. S. National Museum collection. 

 Eleven paratypes, including representatives of both sexes, are being 

 returned to the University of Kansas collection. The species is named 

 for the collector. 



ORASEMA AUREOVIRIDIS, new species 



This species differs from most other species of the genus known to 

 me by having on the propodeum two longitudinal rows of large, 

 shallow foveae that are separated by a more or less sinuate median 

 longitudinal carina. The scutellum dorsally is unusually strongly 

 margined on each side by coarsely foveated and broad longitudinal 

 grooves, which extend from the base of the scutellum to the trans- 

 verse fold or furrow, which is likewise unusually strongly developed, 

 and there is also a shallow depression down the middle of the scutel- 

 lum. The antennal flagellum is more distinctly clavate than usual 

 and the funicle joints, except the first and second, are broader than 

 long. 



Female. — Length 3 mm. Bright metallic green with brassy tints; 

 flagellum black ; scape, pedicel, mandibles, tegulae, and all legs except 

 their coxae pale testaceous; wings hyaline, venation yellowish. 



Head and thorax with nearly uniform, strong, alveolate puncta- 

 tion; parapsidal grooves and sutures at base of scutellum coarsely 

 foveated and median depression on scutellum usually with a few 

 irregularly transverse rugae; coxae distinctly sculptured but more 

 weakly so than thorax ; abdominal petiole with fine alveolate puncta- 

 tion; second sternite as well as the rest of gaster polished; apical 

 tergite faintly reticulately sculptured. 



Antenna rather short; scape cylindrical, not reaching to level of 

 anterior ocellus; pedicel a little longer than broad; ring joint strongly 

 transverse; flagellum slightly increasing in thickness from base to 

 near apex; first joint of funicle about one and one-half times as long 

 as broad and about as broad as pedicel, second joint subquadrate, third
