New Bbitish Columbia 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 Noctuidse, one to the 

 Lasioeampida?, five to the Geometriad;r, one to the Pyralidse, and three to the Tortricidai. They 

 are as follows : — 



Noctuidw. 



Feralia dcceptiva McDuuuough. Described in the Can. Ent., Vol. 52, page 165, June and 

 July, 3020, 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. 



Cwnurgia 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. 



Lasiocampidw. 



Tolypc dayi Blackmore. Described in Can. Ent., Vol. 52, page 226, from seven specimens 

 taken on Vancouver Island — Quainichan Lake (G. O. Day) ; Sluggett's (W. Downes) ; Victoria 

 (E. H. Blackmore). 



Geometrkhu. 



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." 



Eustroma nubilata Pack, form macdunnoughi, Blackmore. Described in Can. Ent., Vol. 52, 

 page 267, Dec, 1920, from twelve specimens taken on Vancouver Island and the Lower Fraser 

 Valley — Duncan (E. M. Skinner) ; Vancouver (R. V. Harvey) ; Fraser Mills (L. E. Marmout) ; 

 Chilliwack (W. B. Anderson) ; Coldstream, Vancouver, Cloverdale, Rosedale (E. H. Blackmore). 



Dysstroma sobria Swett form sicetti 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 mullcolata Hulst in Rep. B.C. Prov. Mus. Nat. Hist., 

 1916, Plate VIII. In the light of later research muUcolata is considered to be the smaller white- 

 bauded form, which is in some years very abundant on Vancouver Island in the month of August ; 

 sivetti occurs in normal years in mid-June and is rather uncommon. 



Anthorhoe incursata Hub. race lagganuta 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. 



Eulype albodecorata Blackmore. Described in Can. Ent., Vol. 52, page 209, Dec, 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, gotliicuta Give., 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. 



PyraUdoe (Pyralinw) . 



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. 



Tortricidw. 



The following three species were described by Messrs. Barnes & Busck in Cont. Lepid. No. 

 Amer., Vol. IV., No. 3. page 215 et seq., March, 1920 : — 



Tortrix dimorphana Barnes & Busck. Described from specimens taken at Duncan. B.C. 

 (A. W. Hanham), and Victoria, B.C. (collector's name not given).
