median carina less strongly developed, the submarginal vein has four 

 to six erect hairs above instead of two, and the propodeum is slightly 

 different. 



Female. Length 2 mm. Antennal pedicel conical, a little shorter 

 than the first funicle joint; ring- joints transverse and apparently three 

 in number; first joint of funicle slightly longer than the second and 

 fully twice as long as thick, second a little longer than the third, the 

 latter ovoid and not one and one-half times as long as broad; club 

 not quite as long as two preceding joints, ovate, distinctly three-jointed 

 and terminating in a short spine, the joints subequal in length, but joints 

 two and three narrowing rapidly toward apex ; antennal depression deep 

 and triangular; malar furrow basally represented by a deep rounded 

 fovea; ocelli large, the lateral ocellus separated from the eye margin 

 by distinctly less than the long diameter of an ocellus; a deep groove 

 runs anteriorly from each lateral ocellus, the two grooves converging in 

 front of the anterior ocellus ; face laterad of the antennal depression and 

 the vertex strongly sculptured; mesoscutum and scutellum lineolately 

 sculptured i praescutum with a faintly indicated non-impressed median 

 line, and two or three rows of pimple-like rugosities along the margins 

 of parapsidal grooves; scutellum apparently with only an apical pair of 

 bristles; grooves of the scutellum not deeply impressed, the sublateral 

 pair with a few pimple-like rugosities similar to those of praescutum; 

 metanotum faintly sculptured with an indistinct median carina; pro- 

 podeum strongly sculptured all over, with a distinct median longitudinal 

 carina and a strong transverse carina, which is more or less interrupted 

 medially; the surface in front of the transverse carina shagreened; 

 behind the transverse carina also shagreened but divided by several 

 more or less distinct longitudinal carinas; marginal vein longer than the 

 submarginal, the stigmal about one-third the marginal and scarcely 

 at all thickened at apex; abdomen subsessile, conic-ovate, and strongly 

 shagreened above. Color metallic blue-green; wings hyaline; antennae,, 

 tegulae, wing veins and the legs for the most part pale testaceous; all 

 coxae concolorous with the thorax, all femora; except apically, blackish 

 brown. 



Male. Length L6 mm. Scape very slightly expanded beneath 

 on apical two-thirds; apparently but one ring-joint, and this very 

 obscure; funicle five-jointed, the first funicle joint very slightly shorter 

 than the pedicel and a little longer than broad; second joint about one 

 and one-half times the first; third and fourth joints subequal and twice 

 as long as the first; fifth funicle joint longer than the first, but shorter 

 than the second; all funicle joints narrower at apex than base, and 

 bearing near base above a half-whorl of hairs approximately twice as 

 long as the joints; the fifth joint has in addition a half-whorl beneath 

 and nearer the base than the dorsal whorl which is located near the mid- 

 dle of segment; club two-jointed, slender, the joints subequal in length, 

 the apical one tapering to a sharp point at apex; the basal joint of club 

 is provided with a whorl of long hairs which are not as long as those of 

 the funicle joints; ocelli large and narrowly separated from the eye
