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 macitlaria 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. Xo. Amer.. Vol. IV., Xo. 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 albifasciata 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. & McD. This is a grey form of exculpata, a new species 

 described from Ketchikan. Alaska. The localities given for the form tribulata are Oregon. 

 Colorado, and Kaslo, B.C. 



Hydriomena perfracta exasperata B. & McD. The race exasperata was described from two 

 specimens taken by the late Rev. G. W. Taylor, one at Departure Bay, near Nanahno, and the 

 other at Wellington. It is evidently very rare. One male specimen was taken by the writer at 

 Victoria on May 10th, 1014. 



Hydriomena renunciata coliunbiata form pernigrata B. & McD. The types of this form 

 came from Glacier Xational Park, Montana ; the paratypes, one male and one female, from 

 Skagit Basin. B.C. ; and one male from Stikiue 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 Xanthorhce, 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 1015, 

 Plate VII., Figs. 5 to 12. 



In the poiitiaria-fossaria group Mr. Swett has just described the following three new species 

 in the Can. Ent.. Vol. 50, Xo. 1. p. 17 et seq.: — 



Xanthorhce macdurmoughi 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. 



Xanthorhce atlinensis Swett. This species was taken at Atlin by E. M. Anderson in 1014, 

 and was described from eight specimens, all male. It is close to fossaria Taylor, which was 

 described from Mount Cheain. Paratypes are in the Museum collection. 



Xanthorhce blactomorei 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. 



BOTAXY. 



During the season of 1017 there have been numerous accessions to the Herbarium of the 

 Provincial Museum, notably the presentation of a large collection of plants of Vancouver Island,
