infuscate basally and apically, their tarsi fuscous; abdomen piceous, tergites 

 narrowly reddish apically. 



Male. Length 4.5 mm.; antennae 4.5 mm. 



Differs from female in practically no way except in sexual characters. 



Type-locality. Rosslyn, Virginia. 



Other localities. Georgetown, D. C., and Coleta, Alabama. 



Type. Cat. No. 19178, U. S. N. M. 



Described from two females from Rosslyn, Virginia, one male 

 from Georgetown, D. C., and one male from Coleta, Alabama, all 

 collected by H. H. Smith. 



The paratypes are very like the type and allotype, but slightly 

 larger in each sex. 



Labrossyta ruficoxalis, new species. 



Differs from frontosa Davis most conspicuously in having the 

 hind coxae testaceous instead of black. 



Female. Length 6 mm., antennae 5 mm. 



Head transverse, broad and strongly convex behind the eyes, subopaque 

 shagreened; face sparsely, finely punctate, nearly twice as wide as long; clypeus 

 about twice as broad as long, convex with a small impression on each side 

 at apex, broadly germinate; malar space half as long as basal width of man- 

 dible; eyes slightly convergent below, about as long as width of face, slightly 

 sinuate opposite antennae; diameter of ocellus less than length of postocellar 

 line, latter equal to ocell-ocular line; scape thick, scarcely oblique at apex; 

 flagellum slightly attenuate at base and apex, first joint a half longer than 

 second, joints beyond middle a third longer than thick; thorax laterally 

 subopaque shagreened and sparsely punctate, mesopleura more or less striate 

 above; mesocutum subpolished and more distinctly punctate; notauli ob- 

 soletely impressed anteriorly; propodeum short, declivous behind, opaque, 

 without carinae except the obsolete lateral longitudinal, distinctly separated 

 from metapleura, spiracles small round; stigma narrow lanceolate, radius 

 far before middle ; radial cell measured on metacarpus equal in length to stigma ; 

 areolet oblique subtriangular, subsessile; nervulus postfurcal; nervellus 

 slightly inclivous, broken slightly below middle; legs long, slender, hind 

 tibia as long as femur and trochanter together, basitarsus nearly as long as 

 rest of tarsus, longer calcarium nearly half as long as basitarsus; abdomen 

 stout, compressed at extreme apex, opaque basally, polished apically; first 

 tergite a half longer than wide at apex, sides nearly straight, with a median 

 longitudinal impression, dorsal carinae strong at base, lateral carinae distinct 

 to spiracles, latter in middle; second and third tergites subequal in length; 

 tergites beyond fifth retracted. 



Black; abdomen, except first tergite, rufous; legs largely testaceous; face 

 at sides, clypeus, mandibles, palpi, spots at origins of notauli, tegulae, humeral 

 and ventral angles of pronotum, spot below tegula, and posterior margin 

 of mesopleura yellow; antennae brown above, reddish below; scutellum
