Trissolcus edessae, new species. 



Differs from brachymenae Ashmead in its greater size, more 

 slender body, and the coarser sculpture of the face. It may be 

 distinguished from the rest of the described species from North 

 America, with the exception of rufiscapus Ashmead, from which 

 it differs in the sculpture of the scutellum, by its entirely yellow 

 scape.

 broadly transverse; face shagreened, covered on the sides with great scattered 

 punctures, with a short truncate projection extending over the bases of the 

 antennae; cheeks uniformly roughly shagreened; scape as long as the club, 

 curved; pedicel as long as the third joint, longer than the fourth and fifth 

 united, and twice as long as wide; fourth and fifth antennal joints broadly 

 transverse; sixth joint forming part of the club, broadly transverse; thorax 

 circular as seen from above; mesonotum roughly shagreened, with notauli 

 distinct for nearly one-half its length and with a delicate median carina, 

 which although very faint anteriorly, extends its entire length; scutellum 

 shining, impunctate; mesopleura impunctate, smooth and shining; abdomen 

 oval, slightly pointed posteriorly; first tergite shining, about four times as 

 wide as long, traversed longitudinally by deep striae; second tergite im- 

 punctate, shining, very shortly striated basally; third a little shorter than 

 fourth and fifth united, the latter two equal in length; sixth broadly trian- 

 gular, as long as the fifth; tergites 3-6 shagreened, with a row of punctures 

 across them; sixth faintly shagreened but without a distinct row of punc- 

 tures across it; wings hyaline, extending beyond the apex of the abdomen. 

 Black; first six joints of the antennae and all of legs except coxae, yellow; 

 mandibles very faintly tinged with red at their apices; nervures pale yellow.
