The female of this typically northern species is most easily recog- 

 nized by the conspicuously exserted hypopygiimi, which is isolated 

 from the eighth tergite and by the metafemur lacking an inner tooth ; 

 the male is recognized at once by the spatulate antennal scape. 



Descriptian. — Black, the pronotimi and mesoscutellimi of female 

 occasionally with indistinct yellow spots, legs more or less red, outer 

 surface of metafemur with base and a ventral spot near apex white 

 or light yellow. 



Female : 4.5-6 mm. Antennae inserted in center of f rons, apex of 

 scape only slightly exceeding level of posterior ocelli, segment 4 

 one-third longer than 5; malar space slightly more than one-half 

 height of compound eye; frontogenal suture slightly curved, 

 almost straight; left mandible with one large dorsal and one very 

 small ventral tooth, right mandible with three teeth, two ventral 

 ones small, blunt and only indistinctly divided, dorsal tooth acute. 



Prepectus narrow, apex not quite reaching tegula ; mesotibial spur
