Genus ANEUGMENUS Hartig. 



ANEUGMENUS FLAVIPES FLAVIPES (Norton.). 



This subspecies occurs from Canada to Georgia and west to Michi- 

 gan. The wings vary from hyahne to the basal portion being strongly 

 infuscate. 



ANEUGMENUS FLAVIPES OCCIDENTALIS, new subspecies. 



Female. — Differs from the typical form in the poorly defined ocellar 

 basin, the lateral walls being present above, but the lower wall is 

 wanting. The antennae are somewhat shorter. Wings hyaline. 



Colorado. One female. 



Type.—Csit. No. 13939, U.S.N.M. 



ANEUGMENUS FLAVITARSIS, new species. 



This and the following new species may be separated from. Jlavipes 

 (Norton) by the lateral walls of the ocellar basin being subparallel, 

 touching the inner margins of the ocelli, the basin being open above. 

 (Injiavipes the basin is triangular, the lateral walls meeting above 

 and between the ocelli.) 



Female. — Length 5.5 mm. Antennal fovese and supraclypeal 

 fovese confluent, the latter hardly defined; supraclypeal area convex; 

 lateral fovese a little above the level of the middle fovea, subcircular 

 in outline; middle fovea transverse, curved, well defined; postocellar 

 fine subequal with the ocellocular; postocellar area convex, sharply 

 bounded laterally; flagellum wanting; stigma broadly rounded. 

 Black shining; labrum, posterior angles of pronotum, tegulse, and 

 legs below bases of coxae pale yellow; apex of clypeus brownish; 

 wings strongly fuscous at base, venation dark brown paler apically. 



Florida. One female collected on ''Palm." 



Type.— Cat. No. 13941, U.S.N.M. 



ANEUGMENUS NIGRIT ARSIS, new species. 



Female. — Length 5 mm. Differs from flavitarsis by having the 

 middle fovea irregularly circular, and the tarsi (apicies of posterior 

 tibiae) black. Anteimse pilose, tapering, third joint distinctly longer 

 than the fourth. 



Male. — Length 5 mm. Very like the female. Hypopygidium 

 broadly rounded apical. 



San Rafael, Jicoltepec, Mexico. Female and two males. 



Type.— Csit. No. 13940, U.S.N.M. 



ANEUGMENUS DIVERSICOLOR, new species. 



Easily known from the other species by the second to sixth abdom- 

 inal segments being ferruginous. 



Male. — Length 5.5 mm. Antennal and supraclypeal fovese 

 shaUow and very poorly defined; supraclypeal area flat; middle 

 fovea transverse, not sharply defined; lateral fovese well defined 

 punctiform; ocellar basin of the type oi jlavipes, but poorly defined
