 Mr. Sherman has made a special study of this family for a number of years and has greatly 

 added to our knowledge of the species occurring within the Province. 



These small flies or fungus-gnats, as tbey are called, resemble mosquitoes or midges to a 

 great degree, but can at once be distinguished by tbe antenna- not being furnished with whorls 

 of hair. 



The abdomen of the male ends in a forceps-like process and in the female in a pointed 

 ovipositor. The larvae feed in fungi and in decaying vegetation and are not injurious, except 

 when they attack cultivated mushrooms. 



Tabanidce (Horse-flics). 



In a recent "Revision of the Canadian species of the affinis group of the genus Tabanus" 

 by Dr. J. McDunnough, Can. Ent, Vol. 53, page 13 ct seq., he has recorded four new species, 

 three of which are described from material wholly or partly collected in British Columbia. 



Tabanus trcpidus McD. This species occurs throughout the Dominion, the type lot containing 

 specimens taken in Ontario; New Brunswick; Nova Scotia: Quebec; Manitoba; and reach- 

 land, B.C. 



Tabanus nudus McD. This species also has the same general range, specimens having been 

 taken in Ontario; New Brunswick; Manitoba; Saskatchewan; and Mount Lehman (Lower Fraser 

 Valley), B.C. 



Tabanus atrobasis McD. The type material of this species is entirely confined to British 

 Columbia, although Dr. McDunnough states that it extends south into Oregon. The holotype 

 is from Mount Lehman, B.C. (S. Hadwen), and the paratypes are from Victoria, Royal Oak, 

 Duncan, and Courtenay. 



Bomhyliidcv (Bee-flies) . 



Calopelta jullav Greene. Described in Proc. Ent. Soc. Wash., Vol. 23, page 23, Jan., 1921, 

 from five specimens. Holotype. allotype, and one female paratype from Colorado, and one male 

 and one female paratype from Royal Oak. B.C., taken on May 19th, 1917, by R. C. Treherne. 

 Calopelta is also a new genus erected by Mr. Greene for the reception of this new species; it 

 differs from the genus Ploas, which it most nearly resembles, by having only two submarginal 

 rolls in the wing instead of three, a feature which was pointed out by Dr. McDunnough. 



Syrphidw (Flower-flies). 



Sjihn ■rophoria cranbrookensis Curran. Described in Can. Ent.. Vol. 53, page IT.".. Aug., 1921, 

 from a single male specimen taken by Mr. C. Garrett at Cranbrook, B.C., on May 25th, 1919. 



Eelomysidce. 



In an article entitled "Notes on HelomyzidaJ and Descriptions of New Species," whiet'. 

 appeared in Ins. Ins. Mens., Vol. IX.. page 119 et seq., July-Sept.. 1921, Mr. C. B. D. Garrett 

 (leserilies eleven new species of this family, ten of which are from British Columbia. They are 

 as follows : —
