bristles. Wings distinctly tinged with brownisli, especially on the distal half, 

 anteriorly; first posterior cell distinctly petiolate at the distal end, the petiole 

 being equal in length to the small cross-vein. 



Habitat, Quebec, Canada (Mr. F. X. Belanger); a single male spe- 

 cimen. The interval between the distal ends of the first posterior 

 and discal cells is a shallow sinus, and not a right angle, as in the 

 following species: 



4r. Bracliyopa notata n. sp. (Loew in litt.) ■? ? . 



Yellowish-ferruginous ; abdomen with brown insisures and with a brown 

 dorsal line ; arista pubescent. Length, 5-6 m. m. 



Face and front pale yellowish, with a yellowish silvery pollen; cheeks with 

 a faint brownish stripe; antennae yellowish-ferruginous; arista yellowish- 

 brown, pubescent; vertex yellowish-ferruginous. Thorax reddish above, 

 clothed with a yellowish pollen, which leaves bare three reddish stripes; the 

 intermediate one geminate. Scutellum reddish-yellow, nearly as long as it is 

 broad; abdomen brownish-yellow, with the hind margins of the segments dis- 

 tinctly, but narrowly bordered wuth brown; lateral margins likewise brown- 

 ish ; in the middle of the back, a narrow, longitudinal brown stripe, some- 

 times interrupted at the incisures, in some specimens evanescent on the fourth 

 segment. Halteres whitish. Legs brownish-yellow, hind tarsi brown. Wings 

 somewhat tinged with brownish-yellow, more distinctly brownish on the apex 

 and along the cross-veins at the distal ends of the first posterior and discal 

 cells; first posterior cell short-petiolate at the distal end. 



Habitat, White Mountains, N. H., beginning of July. Two males 

 and a female. In this species the interval between the distal ends 

 of the first posterior and the discal cell is nearly a right angle. 



I have a fourth specimen, a female, from Quebec (Mr. Belanger), 

 which is smaller, and very pale in coloring, without any brown 

 stripe on the abdomen, the incisures but slightly infuscated, the 

 wings almost hyaline, etc. I take it for a somewhat immature 

 B. noiata. 



5. Criorrhina armillata n. sp. ? . 



Black, thorax bronze color, with fulvous pile ; face, antennae, tip of femora , 

 tibiae and three basal joints of tarsi yellow; tibiae with a black ring in the 

 middle. Length, 11-12 m. m. 



Face and front above the antennae honey-yellow; upper part of front and 

 vertex blackish-bronze color, with fulvous pile; a black spot on the cheeks; 

 antennae yellow-ferruginous, arista black. Thoracic dorsum and scutellum 

 greenish -bronze color, clothed with erect fulvous pile; pleurae and pectus 

 black. Abdomen black, shining, clothed with black pile; a tuft of yellow 

 pile on each side at the base. Halteres yellow. Coxae and about two-thirds
