Plebeius icarioides blackmorei B. & MD. This new race was described by Messrs. Barnes 
& McDunnough in the Canadian Entomologist, April, 1919, page 92, from twenty-six specimens of 
both sexes sent to them by the writer, and taken at Goldstream on May 31st, 1918. In June, 
1916, I captured about six specimens, mostly females, on a small hill some 700 or 800 feet high 
about three miles south of Goldstream; they were new to me, but later I found a pair in the 
Museum collection under the name of Cupido pheres and three specimens in the collection of 
Mr. A. J. Croker under the name Cupido icarioides. Upon further comparison I found that they 
were all conspecific and sent them to Messrs. Barnes & McDunnough for their opinion. Dr. 
MeDunnough stated in his reply that it might prove a good geographical race, but would need 
a good series of both sexes to make sure. In June, 1917, I was collecting in the Lower Irraser 
Valley, and was therefore unable to be at Goldstream at the time of their emergence. The last 
two weeks of May, 1918, were extremely windy, and after waiting a whole week in vain for the 
wind to abate I decided to chance it, and in company with Mr. Arthur Robinson, of this city, 
went to Goldstream. Upon our arrival there the wind was blowing as furiously as ever, and 
the chances of capturing our prized “blue” seemed very remote. However, as we had come so 
far, we decided to walk the remaining three miles to the hill where I had taken them two years 
before. On the top of this elevation is an area of about an acre in extent, totally devoid of 
trees, and covered with blue lupines (Lupinus columbianus Heller), on which plapt the larvie of 
this butterfly feed. Upon reaching this spot the wind was still blowing hard, and the lupines 
~ were bent over at an angle of 45 degrees; the outlook was very discouraging, as we had had 
a long walk, and naturally there was nothing flying in such a wind. After being there a few 
minutes I noticed a “ blue” butterfly hanging on for dear life to the stalk of a lupine that was 
swaying violently in the wind, and to my great delight it was the one we were looking for. 
We then commenced a diligent search, and in the course of an hour and a half “ bottled” over 
forty specimens. This spot seems to be the headquarters of this species, as, although I have 
taken it in two other places in the general vicinity, it has only been very sparingly. On the 
Malahat, some eight miles north of Goldstream, on the side of a small mountain of some 1,200 
feet elevation, there were acres and acres of this blue lupine, over which “ blue” butterflies were 
swarming, and out of over a hundred that were captured only six proved to be this species. 
Cupido pheres, under which name this insect has gone for a number of years, is only known 
from the San Francisco Bay region and typical icarioides from the mountains of California. 
4338. Plebeius icarioides pembina Edw. This is another of our blues that has been mis- 
identified in British Columbia collections for many years, it having passed under the name of 
fulla in the 1904 Check-list, and under the name of ardea in Check-list issued in 1906. Ardea 
is now regarded as a race of icarioides from the Great Basin region (vide Cont. Lepid. No. 
Amer., Barnes & McDunnough, Vol. III., No. 2, page 114). 
ARCTIUD-E (PLATE I.). 
946. Neoarctca beani Neu. This species is a new record for British Columbia, and was 
taken at “light” by Mr. J. W. Cockle at Kaslo on August 20th, 1919. This is one of the most 
interesting finds of recent years, as, although it was described over twenty-eight years ago (Can. 
Ent., Vol. 23, p. 123, June, 1891), I believe that this is the second specimen taken in the adult 
state. It was originally described from Laggan, Alberta, where Mr. T. E. Bean bred several 
specimens from estray larvee which he had picked up in a full-fed state. During the four years 
that Mr. Bean spent in that district he only took one adult specimen, a male, on July 2nd, 1888, 
all the others being bred from estray larvie, which he found feeding on willow, exclusively. In 
the Can. Ent., Vol. 36, p. 350, December, 1904, Wolley Dod writes of having a single specimen 
from Mr. Dean, dated July 9th, 1900; this was also bred from a larva found on willow. The 
only other record I can find of this species is in Gibson's Entomological Record for 1908, where 
_ he states that Mr. N. B. Sanson, of Banff, had sent him a larva of this species, found on Sulphur 
_ Mountain, the resulting imago emerging at Ottawa on June 15th. Mr. Cockle’s specimen is a 
male in fine condition, and we are glad to be able to illustrate this, as he has done so much to 
work up the fauna of the Kootenay country; his untiring efforts for so many years have given 
us a large amount of knowledge which we otherwise would not possess. 
987c. Apantesis blakei diecki Neu. The specimen illustrated was taken by Mr. A. W. Phair 
at Lillooet, but unfortunately bears no date. In Dr. Dyar’s “ List” (Bull. 52, U.S.N.M.) diecki 
is placed as a synonym of determinata, which is a race of williamsi Dodge, but in Cont. Lepid.
