ocellus. Antennal scape cylindrical, not quite reaching the level of 

 lower margin of front ocellus; pedicel as broad as long; ring joint 

 minute; flagellum a little broader than pedicel, not clavate; first 

 funicle joint not quite twice as long as broad, following joints sub- 

 equal and subquadrate ; club indistinctly 3- jointed and a little longer 

 than the two preceding joints combined. 



Forewings about two and one-third times as long as broad, bare 

 basally and with a bare area medially behind the marginal vein; 

 costal cell with a few weak cilia ; stigmal vein approximately two and 

 one-half times as long as broad and nearly perpendicular to the 

 marginal vein ; postmarginal vein less than half as long as marginal. 



Male. — ^Length 2.6 mm. Scape dark, more or less metallic ; flagellar 

 joints distinctly thicker than pedicel; seventh funicle joint very 

 slightly broader than long; abdominal pedicel very nearly twice as 

 long as hind coxa. Otherwise like the female except much more 

 slender. 



Tyjye locality. — Fort Collins, Colo. 



ry;?e.— U.S.N.M. No. 53559. 



Described from 10 females and 2 males. The holotype, allotype, 

 and 7 female paratypes bear C. F. Balder collection No. 1563 and 

 according to his notes were taken in miscellaneous sweepings at Fort 

 Collins, Colo., June 13, 1895. One paratype female with Baker No. 

 1086 was taken at Fort Collins in June on wild-parsnip bloom. One 

 male was taken by Baker at Pagosa Springs, Colo., and a single 

 female was collected by Hubbard and Schwarz at Oracle, Ariz., June 

 7, 1898. 



ORASEMA COCKERELLI, new species 



Differs from wheeleri by having the stigmal vein shorter and not 

 so slender, by having the abdominal petiole slightly shorter, and by 

 its darker color which, however, varies from aeneous black to dis- 

 tinctly green with an aeneous tinge. From vii'idis it can be separated 

 only by the slightly shorter petiole, the nonmetallic scape, and the 

 somewhat darker color of head and thorax. 



Female. — ^Length 2.4 mm. Aeneous black with a slight greenish 

 tinge ; flagellum black ; scape, apices of femora more or less, all tibiae, 

 and all tarsi testaceous; abdomen brownish black; wings hyaline, 

 venation and tegulae brownish testaceous. Antenna weakly clavate ; 

 scape cylindrical, not quite reaching front ocellus; pedicel about as 

 long as broad ; funicle a little thicker than pedicel ; first funicle joint 

 nearly twice as long as broad, second very slightly longer than broad, 

 following joints subquadrate, the seventh a little broader than long ; 

 club a little longer than two preceding joints, rather sharp at apex. 

 Head alveolately sculptured, the alveolae on frons and face a little 

 compressed; postocellar line longer than ocellocular, lateral ocellus
