New Bririsnh Cotumsia INsects. 


























The following seventeen insects from British Columbia have been described as new to science 
during the year 1920. ‘They comprise twelve species of Lepidoptera, one species of Coleoptera, 
two species of Hymenoptera (Parasitic), and two species of Diptera. 
Lepidoptera. 
Of the twelve species of Lepidoptera, two belong to the family Noctuidie, one to the 
-Lasiocampide, five to the Geometriadie, one to the Pyralids, and three to the Tortricidx. They 
are as follows :— ‘ 
‘ Noctuidae. 
Feralia deceptiva McDunnough. Described in the Can. Ent., Vol. 52, page 165, June and 
July, 1920, from two male specimens taken at Vancouver. This species had been previously 
associated with Feralia columbiana Smith. Further notes on both species will be found under 
the heading of “ Illustrated Lepidoptera,” with illustrations of both of them on Plate I. 
Cenurgia erechtea Cram. form parva Blackmore. Described in Can. Ent., Vol. 52, page 226, 
Dec. 1920, from specimens of both sexes taken by the writer at Victoria. 
Lasiocampide. 
Tolype dayi Blackmore. Described in Can. Ent., Vol. 52, page 226, from seven specimens 
taken on Vancouver Island—Quamichan Lake (G. O. Day); Sluggett’s (W. Downes); Victoria 
(E. H. Blackmore). 
Geometrida. 
Lobophora simsata Swett. Described in The Lepidopterist, Vol. 3, page 123, Feb., 1920, from 
fourteen specimens taken by the writer at Victoria. A figure of this species will be found on 
Plate II. and more extended remarks upon it under the heading of “ Illustrated Lepidoptera.” 
Bustroma nubdilata Pack. form macdunnoughi, Blackmore. Described in Can. Ent., Vol. 52, 
page 267, Dec., 1920, from twelve specimens taken on Vancouver Island and the Lower I’raser 
Valley—Dunean (E. M. Skinner); Vancouver (R. V. Harvey); Fraser Mills (L. E. Marmont) ; 
Chilliwack (W. B. Anderson) ; Goldstream, Vancouver, Cloverdale, Rosedale (EH. H. Blackmore). 
Dysstroma sobria Swett form swetti Blackmore. Described in Can. Ent., Vol. 52, page 268, 
Dec., 1920, from ten specimens taken by the writer at Victoria. This large and handsome 
geometer was figured under the name of muileolata Hulst in Rep. B.C. Prov. Mus. Nat. Hist., 
1916, Plate VIII. In the light of later research mullevlata is considered to be the smaller white- 
banded form, which is in some years very abundant on Vancouver Island in the month of August ; 
swetti occurs in normal years in mid-June and is rather uncommon. 
Anthorhée incursata Hub. race lagganata Swett & Cassino. Described in The Lepidopterist, 
Vol. 3, page 131, Feb., 1920, from two specimens taken by the late F. H. Wolley Dod. The male 
holotype was taken at Laggan, Alberta, and the female allotype at Field, B.C., on July 3rd, 1907. 
Bulype alvodecorata Blackmore. Deseribed in Can. Ent., Vol. 52, page 269, Dee., 1920, from 
a long series of both sexes taken by the writer at Goldstream, B.C. This species is apparently 
distinct from hastata Linn., with which it flies, the latter, however, being from a week to ten 
days later putting in an appearance. In a long series of both species I have not known them 
to intergrade, although they are subject to a certain amount of variation within certain limits. 
On the other hand, gothicata Gue., which occurs sparingly at various points on the Mainland, 
shows considerable intergradation with hastata. Until these various forms are bred from the 
egg to the imago our proper understanding of this group will remain incomplete. 
Pyralide (Pyraline). 
Herculia florencealis Blackmore. Described in Can. Ent., Vol. 52, page 270, Dec., 1920, from 
a single female taken by the late W. H. Danby at Rossland, B.C. 
Tortricidae. 
The following three species were described by Messrs. Barnes & Buseck in Cont. Lepid. No. 
Amer., Vol. IV., No. 3, page 215 et seq., Mareh, 1920 :— 
Tortrir dimorphana Barnes & Buseck. Described from specimens taken at Dunean, B.C. 
(A, W. Hanham), and Victoria, B.C. (collector's name not given).
