$. Length, 14"% of wings 10™". Dark ferruginous-red. Head and 

 antenuai shining yellowish-red, arista black, red at base. Face on the 

 sides with a stripe of silvery pollen, not very conspicuous. Dorsum 

 of thorax darker, almost brownish-red, with two rather broad pollinose 

 stripes, abbreviated behind, and inclosing in front a black spot not 

 reaching the suture ; clothed with rather abundant short black hairs, 

 and the bristles of the same color. Pleurae with sparse yellowish pile; 

 metauotum blackish behind. Abdomen narrower than the thorax and 

 much lon.ger, nearly bare, shining, somewhat brownish near the end. 

 Basal joints of tarsi yellowish, the last one or two joints brownish ; 

 femora below near the base, especially on the middle pair, with tufts of 

 yellow pile; the short black bristles of the femora more abundant on 

 the under sides and near the ends, also on the outer sides of the posterior 

 tibipe. Wings brownish in front, lighter behind, base of marginal cell, as 

 far as tip of the auxiliary vein, with a hyaline streak. 



One specimen. 



This species is recorded by Loew from Manitoba (vide O. Sacken's 

 Catalogue, p. 128), and, upon further study, I am convinced that the 

 species which I described as U. rufa must be the same. 



An examination of the specimen identified, as this species in the Loew 

 type collection, since the foregoing was written, confirms this determin- 

 ation. 



BRACHYOPA.*

 sometimes brownish color. Head somewhat narrower than the thorax. 

 Antennae short, third joint round or oval ; arista basal, bare or pubes- 

 cent. Face concave, without tubercle, subcarinate, produced down- 

 wards and forwards considerably below the eyes, truncate at tip. 

 Eyes bare, contiguous in the male, front in female narrowed above, the 

 distance from vertex to antennae greater than thence to oral margin. 

 Thorax narrowed in front. Scutellum large. Abdomen considerably 

 broader than the thorax and scarcely longer, broadly oval. Legs sim- 

 ple, rather strong, the hind femora somewhat elongate, and some times 

 with short bristly hairs below. Wings much longer than the abdomen ;
