“New British CoLuMBIA [LEPIDOPTERA. 
Under this heading we publish an annotated list of those new species and varieties which 
have been described during the past season. We believe that this list will be of value to those 
entomologists in the Province who are unable to keep in touch with all the current literature 
on the subject, but who are desirous of keeping their collections and check-lists up to date in 
nomenclature and scientific arrangement. 
Glaucopsyche lygdamus columbia Skin. This new race of lygdamus was described by Dr. 
Henry Skinner in the Ent. News for May, 1917. The type and paratypes are from Port Columbia, 
Wash. Amongst other localities mentioned for this species is Corfield, Vancouver. We presume 
this is meant for Corfield, near Duncan, on Vancouver Island. This pretty blue butterfly is 
fairly common all over the Island about May, and has been going under the name of G. lygdamus 
behrii Edw. (vide Report, Provincial Museum, 1916). The true behrii is a California race of 
lygdamus, with San Francisco as its probable nimotypical locality; columbia differs from 
behrii in being of a much deeper shade of blue and the spots on the under-side of the wings 
being larger. 
In Vol. III., No. 4, Cont. Lept. No. Amer., March, 1917, Messrs. Barnes and McDunnough 
describe a number of new species and varieties of Geometridz, amongst which are eight new 
to British Columbia. As these *“ Contributions’ were published subsequent to the issuance of 
their new check-list, the following additions must be made to it :— 
Trichodesia albovittata tenuifasciata B. & McD. This form was described from Spirit Lake, 
Idaho. In the Barnes collection there were specimens from Wellington, B.C., and the writer 
has a specimen taken by Mr. W. H. Danby at Ymir in 1900. In this variety the white band 
of primaries is much narrower, being only 1 mm. in width. 
Thera georgii benesignata B. & McD. This racial name has been given to the Vancouver 
Island form on account of its larger size, paler colour, and the strong contrast between the 
brown median and basal areas and the ground colour. Typical georgit is now restricted to 
the Nevada species. The types of Denesignata are from Wellington and the paratypes from 
Duncan. 
Mesoleuca gratulata latialbata B. & McD. Described from three specimens from Plumas 
County, Cal. In this form the median white band is strongly constricted centrally below the 
cell, due to an outward bulge in the dark basal area and a strong inward bend below vein 4 
of the outer dark area. I have a specimen from Kaslo which Dr. McDunnough considers this 
form, although the basal line is not quite typical. 
Bpirrhe plebeculata vivida B. & MeD. ‘This is the species hitherto known as Rheumaptera 
rubrosuffusata Pack., which occurs commonly throughout the Island and Lower Mainland. 
Rubrosuffusata has been found to be a synonym of plebeculata, which was described by Guenee, 
from California, and the racial name of vivida is proposed for our Vancouver Island form on 
account of the coloration being much better defined. 
In deseribing a new species, Phasiane ponderosa, Messrs. Barnes and McDunnough mention 
a variety of it under the form name of demaculata, in which the cross-lines tend to become 
obsolescent, especially in the females. The types are from Calgary, Alta., but one of the female 
paratypes is from Field, B.C. We have two rather worn females, one from Atlin, taken by E. M. 
Anderson, and one from Chilcotin, taken by W. A. Newcombe, so that although uncommon it is 
widely distributed. 
Itame plumosata B. & McD. This pretty yellow and brown geometer was described from 
specimens taken in various localities in Arizona and Utah. We have a male specimen from 
Mount McLean near Lillooet, taken in July, 1916, by E. M. Anderson. It is rather remarkable 
that this species should turn up here, as it is a long way from its nimotypical locality; it is 
apparently a high altitude species and may turn up on any of the high mountains in the inter- 
vening country. 
Cleora satisfacta B. & McD. Described from one male and one female taken at Kaslo. 
This is closer in general habitus to exrcclsaria Streck and albescens Wulst. than to any other 
Cleora that occurs in the Province. _ 
Bthaloptera anticaria fumata B. & McD. This is the insect from Kaslo that has been 
previously known as 4/. intertala Walk. Dr. McDunnough states that anticaria should be used 
for the common Eastern species instead of intexrtata, and proposes the name of fumata for the
