Female.— Liength. 6 mm.; length of the antenna 4 mm. Clypeiis 

 flat, shining, slightly convex in the basal middle, anterior margin 

 rather deeply arcuately emarginate; lobes triangular in outline, 

 rather sharply pointed; supraclypeal foveae deep, punctiform; mid- 

 dle fovea shallow, circular in outline ; ocellar basin entirely wanting ; 

 antennal furrows nearly complete; a small wedge-shaped depression 

 in front of the anterior ocellus; postocellar line subequal with the 

 ocellocular line, and but little shorter than the ocelloccipital line: 

 postocellar area convex, sharply defined laterall3% with a small fovea 

 in the anterior middle; postocellar furrow wanting; antenna rather 

 short, sharply tapering; the third joint distinctly longer than the 

 fourth; the apical joint somewhat longer than the preceding; stigma 

 short, rounded below, its greatest width at about the middle; first 

 intercubitus obsolescent; second cubital cell on the radius subequal 

 with the third; radiellan cell with distinct appendage; sheath 

 straight above, obtuse at apex, tapering from the broad base. Black; 

 anterior tibiae and tarsi, the posterior tibiae and most of the pos- 

 terior tarsi white ; posterior margin of the tegulae whitish ; wings

Type locality. — Northeast, Pennsylvania. 



Described from one adult which was reared from a larva collected 

 on Blackberry. This larva formed a cocoon on June 11, was a 

 pupa on June 16 and an adult on the 23 and emerged on the 24. 

 Material collected and reared by R. A. Cushman. 



Type.— Cut. No. 21594, U.S.N.M.

 short and obtuse, apically; supraclypeal foveae punctiform, middle 

 fovea elongate, deep, Avith sloping walls, not breaking through the 

 frontal crest; lower wall of ocellar basin defined, the lateral walls 

 are obsolete ; antennal furrows wanting below the ocelli ; postocellar 

 area flat, sharply defined laterally, with an elongate fovea in the 

 anterior middle; postocellar furrow wanting; postocellar line 

 slightly shorter than the ocellocular line; antenna short, the third 

 and fourth joints subequal, the apical joint subequal with the pre- 

 ceding (see figs. 15 and 33) ; stigma short, broadest at base, gradually
