THE CANADIAN ENTOMOLOGIST 223. 



short and not deep, the lateral ocelli far distant from the eyes; 

 pronotum not long, the parapsidal furrows complete, the head and 

 thorax smooth. Antennae 12-jointed, the ring-joint large, nearly 

 as long as wide, the funicle apparently compressed, the joints all 

 transverse and lamellate or produced toward one side, the distal 

 joint much less so and largest of the funicle; pedicel subquadrate, 

 much longer than the proximal funicle joints; club long-ovate, 

 longer than the cylindrical, simple scape, its joints obliquely trun- 

 cate, the distal joint short and conic. Fore wings normal, the mar- 

 ginal cilia sparse and short. Propodeum with a bright median 

 carina, its spiracle large and nearly round. Abdomen short and 

 stout, no longer than the thorax, its second segment occupying half 

 of the surface. Scutellum longer than the propodeum. Parap- 

 sidal furrows complete. Posterior tibiae apparently with but one 

 apical spur. 



Male. — The same, the abdomen more depressed and cylin- 

 drical; antennae entirely different, the scape much shorter, dilated 

 ventrally, the antennae 12-jointed, the pedicel not much longer than 

 thick, the ring-joint like a ring, the first funicle joint very 

 transverse and lamellate; following five funicle joints very 

 transverse and increasing in length, each bearing a long, 

 curved, cylindrical ramus from its disto-lateral margin, joint 

 2 no longer than the diameter of its ramus and practically 

 forming a continuation of it; joint 3 slightly larger than 

 wide; joint 6 much longer than wide; the ramii longer 

 proximad, the shortest and distal one distinctly longer than any 

 single joint of the antenna. Proximal joint of club elongate, ob- 

 conic, forming half of the club and longer than the distal funicle 

 joint; the other two club joints subequal. Funicle and ramii with 

 sparse, long fine hairs. 



Type. — The following species (flavipes). 



Female. — Length, 3 mm. 



Black and shining, the face, genae, legs (except coxae, the tarsi 

 more brownish), scape (except at tip, where it is blackish) the mar- 

 gin of the eyes dorsad and caudad more or less obscurely, lemon

 the yellow of the face, some distance directly cephalo-ventrad of the
