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 they are called, resemble mosquitoes or midges to a 
great degree, but can at once be distinguished by the antennie 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 larvie feed in fungi and in decaying vegetation and are not injurious, except 
when they attack cultivated mushrooms. 
Tabanide (Horse-flies). 
In a recent “ Revision of the Canadian species of the afinis group of the genus Tabanus” 
by Dr. J. McDunnough, Can. Ent., Vol. 58, page 13 et seq., he has recorded four new species, 
three of which are described from material wholly or partly collected in British Columbia. 
Tabanus trepidus McD. This species occurs throughout the Dominion, the type lot containing 
specimens taken in Ontario; New Brunswick; Nova Scotia; Quebec; Manitoba; and Peach- 
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. MeDunnough 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, 
Dunean, and Courtenay. 
Bombyliide (Bee-flies). 
Calopelta fallax Greene. Described in Proc. Ent. Soe. 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 haying only two submarginal 
cells in the wing instead of three, a feature which was pointed out by Dr. MeDunnough. 
Syrphide (Flower-flies). 
Sphwrophoria cranbrookensis Curran. Described in Can. Ent., Vol. 55, page 175, Aug., 1921, 
from a single male specimen taken by Mr. C. Garrett at Cranbrook, B.C., on May 25th, 1919 
Helomyzida, 
’ 
In an article entitled “Notes on Helomyzidw and Descriptions of New Species,” which 
appeared in Ins. Ins. Mens., Vol. IX., page 119 et seq., July—Sept., 1921, Mr. C. B. D. Garrett 
describes eleven new species of this family, ten of which are from British Columbia. They are 
as follows :— 
Leria aldrichi. Cranbrook, March. 
Barbastoma barbatus. Sheep Creek, October. 
Postleria fuscolinea. Cranbrook; Michel, May—June—August. 
Amebaleria scutellata. Cranbrook, May. 
Amebaleria gigas. Cranbrook; Michel, March to August.
