Kaslo race, which is more evenly suffused with smoky brown and with the lines more or less 
obsolescent. The types are six males from Kaslo, presumably taken by Mr. J. W. Cockle. This 
locality is the only one from which we have any record of this species. 
In addition to the foregoing, it is as well to note that Messrs. Barnes and McDunnough have 
given the study of Sicya macularia Harris and its various races considerable attention, with the 
result that crocearia Pack. is rescued from the synonymy and applied to the form that occurs 
in the Great Basin Region of the United States, and also to a similar form occurring on Van- 
couver Island. For the benefit of those collectors who may think that they have two different 
varieties of this species, it is as well to add that this form is sexually dimorphic. In a long 
series taken by the writer it is noticeable that while the females in general are much scarcer 
than the males, the dimorphic female is far more prevalent than the ‘typical one. 
In Cont. Lep. No. Amer., Vol. IV., No. 1, May, 1917, Messrs. Barnes and McDunnough have 
revised the whole of the genus Hydriomena. Many radical changes have been made and new 
species added, some of which refer to our British Columbia forms, so that it will be advisable 
for collectors to alter their check-lists accordingly. 
Hydriomena ailbifasciata victoria B. & McD. ‘This has always been listed as reflata Grt. in 
British Columbia collections, but this name has been restricted to an Arizona race of albifasciata, 
and the name victoria has been given to the Vancouver Island form; the types being three males 
and two females from Victoria. 
Hydriomena exculpata tribulata B. & MeD. This is a grey form of erculpata, a new species 
described from Ketchikan, Alaska. The localities given for the form tribulata are Oregon, 
Colorado, and Kaslo, B.C. 
Hydriomena perfracta erasperata B. & McD. The race erasperata was described from ‘two 
specimens taken by the late Rev. G. W. Taylor, one at Departure Bay, near Nanaimo, and the 
other at Wellington. It is evidently very rare. One male specimen was taken by the writer at 
Victoria on May 19th, 1914. 
Hydriomena renunciata columbiata form pernigrata B. & McD. The types of this form 
came from Glacier National Park, Montana; the paratypes, one male and one female, from 
Skagit Basin, B.C.; and one male from Stikine River, B.C. The latter probably collected by 
Theodore Bryant, of Ladysmith, who collected in that district when with a survey party. 
Hydriomena edenata grandis B. & McD. The racial name of grandis has been given to our 
Vancouver Island form, which has been previously known as edenata Swett. Typical edenata, 
which was described from Eden Valley, Monterey County, Cal., is very much smaller than the 
one we get here and is shaded with a warm brown, while our form is tinged with green. 
The genus Xanthorhe, which contains several distinct groups of species, has been badly 
mixed up in the past, and much misidentification of species has ensued. 
As it was also felt that there were several species, or at least good varieties, going under the 
same name, the writer collected extensively in this genus for several years, with the result that 
Mr. L. W. Swett, the well-known geometridist, described several new forms of the defensaria 
group, which were illustrated in the Annual Report of the Provincial Museum for the year 1915, 
Plate VII., Figs. 5 to 12. 
In the pontiaria-fossaria group Mr. Swett has just described the following three new species 
in the Can. Ent., Vol. 50, No. 1, p. 17 et seq.:— 
Xanthorhe macdunnoughi Swett. This occurs all over the southern portion of Vancouver 
Island, but it is not common by any means. The types are from specimens taken by the writer 
at Victoria. Paratypes of each sex have been placed in the Museum collection. 
NXanthorhe atlinensis Swett. This species was taken at Atlin by I. M. Anderson in 1914, 
and was described from eight specimens, all male. It is close to fossaria Taylor, which was 
described from Mount Cheam. Paratypes are in the Museum collection. 
Xanthorhe blackmorei Swett. Described from material taken by the writer at Goldstream 
and Victoria. This species is very distinct, as in most cases the blackish median band becomes 
obsolescent below the median vein. A male paratype has been placed in the Museum collection. 
Illustrations of these new species will be found in an accompanying plate. 
BOTANY. 
During the season of 1917 there have been numerous accessions to the Herbarium of the 
Provincial Museum, notably the presentation of a large collection of plants of Vancouver Island,
