M 44 British Columbia. 1022 



The British Columbia specimens are very variable, both in size and in coloration. The 

 Wellington examples are the largest, being 21-22 mm. in expanse, with the dark shades con- 

 trasting with the paler areas, which are a deep cream. A series from Goldstream average 

 18 mm. in expanse and are very pale, the ground colour being a sordid white, with the brown 

 sput before cleft distinctly marked. Those from Eraser Mills are similar, but not quite so pale. 

 Some Kaslo specimens are as pale as my Goldstream series, but a trifle smaller, although one 

 specimen is larger than any, measuring 23 mm., and in addition is very much darker, the ground 

 colour being dark brown. Dr. Lindsey has seen this specimen and pronounced it corvus, believing 

 that the brown colour is due to age or some other cause. It was taken on June 20th, 1904. 



The life-history and food-plant are unknown, although the series which I took at Goldstream 

 in August. 1920, were all beaten from the common yarrow (AchilUa millefolium), which may 

 be its food-plant. I did not observe it on any other plant. 



11. Oid.ematophoeus MONODACTTLUS Linnreus, Syst. Nat. (Ed. 10), page 542, 1758. The 

 colour of the primaries is very variable, ranging through shades of grey, yellow, and brown to 

 various mixtures of these colours. The fore wings are very narrow, but have unusually long 

 fringes at the anal angle of the second lobe. There is a black spot before base of cleft, some- 

 times extended to it, a dot in cell, some at tips of veins in both lobes, and some black scales 

 streaking the wing near inner margin. Secondaries and fringes of both wings brownish-grey. 

 Expanse 21-28 mm. Thorax similar to primaries. Abdomen brownish or greyish with some 

 dark dashes, and a narrow dorsal stripe concolorous with thorax, which widens anteriorly and 

 is usually margined with white toward its junction with the thorax. There is usually a crest of 

 scales present on the upper surface of the hind tarsi. 



This is our commonest species on Vancouver Island and it has been taken in every month of 

 the year. The most common coloration is tawny, with a sprinkling of grey forms and a few 

 red-brown ones. I have not seen any specimens from the Mainland, which is rather surprising, 

 as it occurs right across the continent from the Atlantic to the Pacific and from Mexico to 

 Canada. It also occurs iu Europe, Asia, and North Africa. It feeds on a large number of- 

 different food-plants. 



The following eight species recorded in the 1906 B.C. Check-list are omitted from this paper 

 for the reasons given : — 



Triclioptilus lobidactylus Fitch. Recorded from Wellington. I have examined the specimens 

 labelled as this species in the Bryant collection and from which the records were taken for the 

 above list, and find that they are all Pterophorus dehiuaricus Zeller without a doubt. 



Oxijptilus (Pterophorus) pcriscclidactylus Fitch. Recorded from Wellington. The speci- 

 mens labelled as such in the Bryant collection are Platyptilia punetidactyla Haw. 



Platyptilia Shasta Wals. Recorded from Wellington. This was rather an extraordinary 

 determination, as specimens bearing this label were undoubtedly Oidatmatophoinis cineraceus 

 Fish. A totally different insect and bearing no resemblance, either generic-ally or specifically. 



Platyptilia grandis Wals. and Platyptilia modesta Wals. Both recorded from Wellington. 

 Specimens bearing these labels were nothing more or less than specimens of the common 

 carduiddctyla, which had apparently been separated according to their size: the latter species 

 being very variable in this respect, as I have specimens ranging from 18 to 28 mm. in expanse. 



Pterophorus (OidcBinatvphorus) brucci Fern. Recorded from Sbawnigan Lake by Dr. Dyar 

 in his "Kootenai List." In his annotation be states: "Iwo specimens ... in poor 

 condition, but seeming to agree with specimens from Colorado, so named for me by Dr. ('. II. 

 Fernald." 



1 am rather inclined to doubt the correctness of Dr. Dyar*s determination of this species on 

 the following grounds: (1) That hntcei Fern, and mathetcianus Zell. have a somewhat super- 

 ficial resemblance; (2) that Dr. Dyar'S specimens were in poor condition and he himself was 

 not positive that they were eonspecific with his Colorado specimens of bntcei; <:>! that 

 apparently Dr. Dyar did not have at that time specimens of mathcvcianus for comparison; (4) 

 that specimens sent to me by Mr. Cockle, of Kaslo, ms brucei have been determined by Dr. Lindsey 

 as matlicirianiis ; and (5) that of 250 specimens of this family recently examined from 

 many diverse localities in the Province, not a single speciufen turned up which has been even 

 doubtfully referred to bntcei. Taking all those facts into consideration, it is more reasonable 

 to suppose thai Dr. Dyar's specimens were in reality iiiiiIIk iriiinns. which was originally described
