BY HARRISON E. SMITH,

Saskatchewania, new genus. 



Proboscis long, slender, about two times as long as the dorso- 

 ventral diameter of the head. Labella not well developed. Palpi 

 small, well developed. Head slightly broader than the thorax. 

 Facial plate with broad, highly raised, distinct median carina. 

 Facial ridges bare. Eyes bare. Antennae inserted near a line 

 drawn through the middle of the eye, descending but slightly 

 below the middle of the face. Parafrontals bare outside of the 

 frontal row. Frontal bristles not descending below base of anten- 

 nae. Ocellar bristles weak, proclinate. Orbital bristles absent in 

 each sex. Diameter of head at the vibrissae as long as at the base 

 of antennae. Abdomen not bearing the usual macrochaetae. Tip 

 of apical cell ending at the extreme wing tip. Apical cell closed, 

 long petiolate, the petiole as long or slightly longer than the 

 posterior cross-vein. Posterior end of the hind cross-vein nearer 

 to the small cross-vein, than to the margin of the wing. Fourth 

 longitudinal vein, beyond the bend, with a short distinct stump.

Saskatchewania canadensis, new species. 



Black, densely brassy-gray pollinose. Length 5-6 mm. 

 Frontal vitta bright opaque, brownish black, slightly concave. 

 At narrowest part somewhat wider than the parafrontals at the 

 same point. Front at narrowest part not more than two times as 

 wide as the distance between the posterior ocelli. Ocellar triangle 

 and sides of front grayish pollinose. Head as viewed from the side 

 projects but little in front of the eye. Parafacials grayish pol- 

 linose with a strong brassy tinge; about one-fifth as wide as the 

 median depression. Cheeks covered with black bristly hairs, 

 gradually simulating macrochaetae on the anterior margins. About 

 one-fifth to one-fourth as wide as the eye height. Transverse 

 impression of face well defined, concave, piceous. Antennae black, 

 the first joint scarcely discernible, brownish black. Second and 

 third joints opaque black, the third joint not over two times as
