supraclypeal area flat; anteimal furrows strong, complete; ocellar 

 basin small, well defined; postocellar furrow well defined, angulate 

 anteriorly; postocellar area somewhat wider than long; postocellar 

 line about two- thirds as long as ocellocular line; third antennal joint 

 much longer than the fourth; mesonotum opaque with close, fuie 

 punctures; scutellar appendage coarsely punctured; stigma gently 

 tapering to the apex; second cubital cell shorter on both the radius 

 and cubitus than the third ; receiving the first recurrent vein near the 

 middle ; third cubital cell receiving the second recurrent vein near the 

 basal fourth; legs normal; sheath straight above, convex below, the 

 apex rather narrowly rounded. Black; clypeus, labrum, spot on the 

 mandibles, posterior margin of the eyes, inner margin of the eyes, 

 posterior margin of the pronotum, tegulse, 4 anterior legs beneath 

 from the apices of the femora, the bases of the posterior tibiae beneath, 

 and sides of the propodeum yellow; wings hyaline, behind the bases 

 of the stigma strongly dusky; venation black. 



BUtmore, North Carolina. Described from 1 female collected 

 June 27, 1912, by W. L. McAtee. 



Type.— Cat. No. 15244, U.S.N.M. 



TENTHREDELLA FISHERI, new species. 



Allied to Tenthredella angulifera (Norton), but the yellow on the 

 mesonotum and the black pectus will readily separate it from this 

 species. In some characters this agrees with the description of 

 ventralis Say, but there is not sufficient evidence to prove that this is 

 Say's species. 



Female. — Length 10.5 mm. Labrum short, anterior margin 

 broadly rounded; clypeus arcuately emarginate, the lobes truncate; 

 supraclypeal foveas small, punctiform; supraclypeal area flat; antennal 

 furrows complete but not sharply defined; ocellar basin shallow, 

 V-shaped above the anterior ocellus; postocellar furrow straight, 

 well defined; postocellar area nearly quadrate; postocellar line a little 

 more than half as long as the ocellocular line; third antennal joint 

 longer than the fourth; mesonotum shining, with a few scattered, well 

 defined punctures; stigma tapering to the apex; second cubital cell 

 distinctly shorter than the third; legs normal; sheath slightly con- 

 cave above, slightly convex below, broadly rounded apically. Black; 

 clypeus, labrum, mandibles except piceous apices, face below anten- 

 nas, two spots above the antennae, cheeks, posterior margin of the 

 head, inner margin of the eyes extending to the vertex and uniting 

 with a band on the posterior margin of the head, two small spots 

 on the posterior margin of the postocellar area, spot on sides of the 

 pronotum, posterior margin of the pronotum, tegulae, lateral margin 

 of the prescutum, two spots on the scutum just behind the prescutum, 

 large spot on the scutellum, scutellar lobe, vertical spot on the
