$ . — Length 1.8 mm. Black, with third abdominal segment and the 

 legs rufous or yellowish. Head and thorax closely punctulate and almost 

 opaque ; face polished, with a delicate central carina ; lower cheeks and 

 face below antennas with strife converging to mouth ; mandibles yellowish, 

 palpi white. Antennae black, except base of scape, which is rufo-piceous; 

 pedicel small, first funicular joint twice as long as pedicel, second one- 

 third shorter than first, third as long as pedicel, fourth small, subquadrate; 

 club compact. Mesonotum without furrows ; mesopleura with striae con- 

 verging toward pectus ; metathorax rugosely sculptured. Wings hyaline, 

 pubescent ; marginal vein thickened, as long as stigmal. Legs, including 

 coxae, honey-yellow ; the anterior coxse varying to subpiceous. Abdomen 

 subfusiform, longer than thorax and head, black at base and apex ; third 

 segment and part of second rufous ; horn reduced to a polished convex-

 closely finely punctulate. 



Described from three females captured 19th and 29th August, 1894, 

 by sweeping the low herbage of sandy pastures within city limits of 

 Ottawa. 



Superficially this species resembles OpistJiacanta vidlipes, Ashm., 

 but is readily distinguished by the absence of mesonotal furrows and of 

 the metascutellar spine.

 black ; first funicular joint twice as long as pedicel, second one-third 

 shorter, third as long as pedicel, fourth small transverse ; club consisting 

 of six joints subequal in length. Mesonotum punctulate and pubescent, 

 with faint furrows. Wings faintly yellowish, pubescent, with long cilise 

 on costal margin ; usually hardly reaching to apex of third segment of 

 abdomen, but in one specimen more fully developed and extending 

 almost to tip of the abdomen. Legs yellow, the knees sometimes darker. 

 Abdomen longer than head and thorax ; first and second segments striate, 

 third segment almost quadrate, very highly polished, but faintly micro- 

 scopically punctate, as are also the terminal segments, which, however,
