8 THE CA.NADIAN -ENTOMOLOGIST. 



30. Xmithogramma tenuis^ sp. nov. (Fig. 3.) 



Female. — Face, cheeks and oral margin yellow, the yellow continued 

 above on the sides of the front to the vertex. Vertex and middle of the 

 front nearly to the antennae bronze-black. Pile very fine and delicate, 

 that of the face whitish, of the front and vertex black. The contour of 

 the face below the antennie is straight to the tubercle, which is rounded 

 and moderately prominent. Thorax bronze-black, the lateral stripes 

 yellowish, rather obscure ; a large obscure whitish patch on the pleura. 

 Scutellum yellow, with dark reflections, the anterior angles blackish. 

 Pile of the thorax and scutellum yellowish, very delicate. Abdomen 

 black, somewhat shining, yellow as follows : a spot on each side of 

 segment i, cross-bands on the anterior part of segments 2, 3, 4 and 5 

 interrupted at the middle and reaching the margin broadly ; segments 5 

 and 6 very narrowly yellow on the posterior border. Legs yellow, a 

 broad dark ring on the hind and middle femora and tibiae, and the hind 

 tarsi infuscated. Halteres yellow. Wings hyaline, stigma yellow. 



Length, 7 mm., a weak-looking, delicate species (/^/2z^/^ = slender). 

 One specmen taken by Mr. R. V. Harvey in the Hope Mts., July 27, 

 1906. 



This species resembles most vS. emarginata^ Say, but differs from it 

 in the facial contour, the interrupted abdominal cross-bands, the smaller 

 size and more slender form. 



31. Toxoinerus ( Mesogramvia) boscii, Macquart. 



Kaslo, June 11, 1903, H. G. Dyar. (Identified by Coquillett.) This 

 species, formerly known only from south-eastern North America, has 

 recently been recorded by Chagnon from Montreal, and by Washburn 

 from Minnesota. 



32. Hamvier Schmidt ia ferriigiiiea^ Fallen. 



Kaslo, June 15, 1903, R. P. Currie, and June 14, 1906, J. W. 

 Cockle. The specimen taken by Mr. Cockle is much darker than any 

 others I have seen, so much so that its general aspect is dark instead of 

 reddish. On closer inspection in strong light the ground colour appears 

 through the darker pigment. A specimen from Ft. Morrison, Colorado, 

 in the U. S National Museum, is intermediate in colour. 



33. Brachyopa notata, O. Sacken. 



April 13, 1906, at Vancouver, ten specimens taken at cherry bloom 

 by R. V. Harvey; April 28, 1906, R. S. Sherman.
