LyMANTRIID% (PLATE I.). 
3704 (b.) Hemerocampa vetusta gulosa Hy. Edw. This moth, which has hitherto not been 
recorded from British Columbia, is very interesting from both a systematic and economic stand- 
point. It was discovered by Mr. W. B. Anderson, who is Dominion Inspector of Indian Orchards, 
on one of his periodical trips in the Interior. It was taken at Chase, B.C., where it was doing 
much damage to the Douglas fir. Imagines and full-fed larve were taken together on August 
6th, showing it to be double-brooded. The females are wingless and live solely for the purpose 
of oviposition; having laid her eggs she covers them with hairy scales, which she plucks from _ 
her body and mixes them with a gummy secretion, which on drying becomes hard and brittle; 
as her mission in life is then ended, she dies. 
The full-fed lary noted above spun up about August 12th, emerging in the breeding-cage 
on September 1st and 2nd. There are three closely allied forms—vetusta Bdy., described from 
the Coast region of California in 1852; gulosa Hy. Edw., described from the same general 
locality in 1881; and cana Hy. Edw., described from the Sierra Nevadas of California in the 
same year. After a careful comparison with the descriptions published by Neumoegen and 
Dyar in their “ Preliminary Revision of the Bombyces of America,” Jn. N.Y. Ent. Socy., Vol. II., 
p. 29, March, 1894, I have not the slightest hesitation in referring this British Columbia form 
to gulosa, which together with cana are made races of vetusta in Barnes and McDunnough’s 
new Check-list. It is also a near relative of H. leucostigma A. & S. (the white-marked tussock- 
moth), whose ravages upon shade-trees and shrubbery in the Atlantic States are well known. 
GEOMETRID.Z (PLATE IT.). 
4002 (a.) Dysstroma formosa boreata Tay]. This is rather an interesting record, as its 
capture is of very rare occurrence. It was taken near Victoria by Mr. W. Downes on July 28rd, 
1917. It was described in the Can. Ent., Vol. XLII., p. 87, March, 1910., from two specimens 
taken by Mr. T. Bryant near the Stikine River, in Northern British Columbia, on July 24th 
and 25th, 1905. Im Barnes and MeDunnough’s new Check-list it is placed as a race of formosa 
Hulst., and in my opinion rightly so, as the maculation is practically the same, with the exception 
of the extra basal bar, which is quite distinct and perfectly black instead of red or orange. 
Typical formosa, which was described from Colorado, also occurs in British Columbia, the 
writer haying in his cabinet a rather poor specimen taken at Lillooet on June 23rd, 1916, and 
there is a specimen in the Swett collection taken by the late Mr. Livingstone at Cowichan 
Bay, B.C. 
* Hydriomena macdunnoughi Swett. This specimen, new to science, is noted fully under 
the heading of “ New British Columbian Insects.” 3 
* Hydriomena perfracta exasperata B. & McD. In last year’s Museum Report mention was 
made of the new forms of //ydriomena, described by Messrs. Barnes and McDunnough in their 
revision of that group, Cont. Lept. No. Amer., Vol. IV., No. 1, May, 1917. The specimen figured 
is one of them and was taken by the writer near Victoria on May 19th, 1914, whilst beating for 
Geometride. It was described from two specimens, both males, one taken at Departure Bay 
and the other at Wellington, both localities being on Vancouver Island; it is a geographical race 
of perfracta Swett, whieh is taken in the Catskill Mountains, N.Y. The latter was originally 
described as a variety of carulauta Fabr. (autumnalis Strom), but is now considered as distinet, 
on account of difference in the shape of the uncus in the two forms. 
4860 (a.) Phasiane respersata teucaria Stkr. This little geometrid was listed in the 1906 
B.C. Check-list as Macaria teucaria with a question-mark; later it was determined as respersata . 
Hulst., but finally it has been identified as tewcaria, which was described from Seattle, Wash., 
and is really only a large form of respersata, whose nimotypical locality is Colorado. Teucaria 
occurs on Mount Tzouhalem, near Dunean, and although I haye collected assiduously in the 
vicinity of Victoria for the past eight seasons, I had only taken two specimens until last May 
(1918), when I took thirty-seven at Mount Tolmie on May 28th. In a long series they are rather 
variable as regards the intensity of the markings, and also in the presence or absence of the 
intradiscal line; in some forms this line is present from the costa to the median vein only, 
giving the insect quite a different appearance. (For earlier notes on this species see Proc. Ent. 
Socy., B.C., No. 6, p. 110, June, 1915.) 
4372 (b.) Phasiane neptaria sinuata Pack. Both neptaria Gu. and sinwata have been listed 
in previous B.C. Check-lists as occurring here, the latter being retained in the list on account
