M 38 British Columbia. 1922 



and below. Thorax mostly whitish in front and behind, brownish ochreous across tips of patagia. 

 Expanse, 20-20 mm. 



A very rare species. There is only one record from British Columbia — a single specimen 

 taken by Mr. G. O. Day in June. The type came from Northern Oregon, where they were reared 

 from a species of Orthocarpus. Writing of orthocarpi, Barnes and Lindsey state that " Together 

 with fragilis, shastw, and albida, they make up an extremely difficult group which we are 

 inclined to believe in a state of evolution. The named forms can be recognized, but whether 

 to regard them as forms and races of one species or as distinct species is a question which 

 we are unable to decide." 



8. Platyptilia fkagilis Walsingham, Pter. Cal., Ore., 16, 1880. In this species the 

 characters are much the same as in the preceding, except that the general colour is more or less 

 buff or light brown. Expanse, 20-24 mm. 



In the Bryant collection several specimens stood under the name of fragilis, but upon exami- 

 nation they all proved to be albiciliata Wals., with the exception of one specimen, which 

 Dr. Lindsey agrees is fragilis. The specimen is a little undersized, barely measuring 18 mm. 

 It lacks antenna? and abdomen, but is otherwise in good condition. It was taken by Mr. Bryant 

 at Wellington on July 13th, 1903. The species occurs in Washington, California, Arizona, and 

 Colorado. 



9. Platyptilia albiciliata Walsingham, Pter. Cal., Ore.. 17, 1SS0. Fore wings even dull 

 brown, dark triangle faintly indicated. Fringes greyish with pale bases which bear a row of 

 dark scales on the outer margin. Secondaries are coucolorous, their fringes with pale bases, 

 sometimes conspicuous, and a few scattered brown scales along the inner margin of the third 

 lobe. Expanse, 21 mm. Thorax somewhat lighter behind. Palpi are moderate, oblique, and the 

 frontal tuft very short and blunt. 



British Columbia examples differ from the above abbreviated description, in having the dark 

 triangle well marked and the outer pale line discernible on the first lobe in most specimens. 

 There is also some irroration of bluish-white scales on the disk and along the costal edge ; in 

 some specimens this irroration is extended to the terminal area of both lobes of the primaries. 

 The species has been taken at Wellington (Bryant) ; Mount McLean (Day) ; and at Barker- 

 ville (Buckell). The single specimen taken by Mr. Buckell is a darker brown than the other 

 British Columbia specimens and of a more even colour. The species was described from North 

 California. There is a specimen from Montana in the Barnes collection which is doubtfully 

 referred to this species. The early stages are unknown. 



10. Platyptilia albicans Fish, Can. Ent„ XIII., 71, 1881. Primaries creamy white with 

 white-irrorate brown areas, the colours about equally extensive. Both lobes with a terminal 

 brown band and one just before middle which fades out toward inner margin. Costa brown 

 as far as base of cleft and inward to a transverse dash before cleft. Fringes white with grey 

 tips; brown and white scales in bases along outer margin. Secondaries grey-brown with a 

 faint tuft of slender scales, not visible without lens, near middle of inner margin of third lube. 

 Expanse 17-24 mm. Frontal tuft lacking. Palpi small and slender, but projecting well beyond 

 front ; brownish on sides. 



The only records for British Columbia are specimens taken by Mr. G. O. Day. One taken 

 at Hope Mountains in July, 1908, and another one taken on Stokers Mountain, near Cowichan 

 Lake, on July 23rd, 1909. AVriting on the species, Barnes and Lindsey remark "that the Stoker 

 Mountain specimen is anomalous. We place it here with little hesitation, though it is so much 

 darker than the typical form that a casual examination discloses little resemblance. It corre- 

 sponds in essential features with our series, but differs in having the brown areas darker and 

 more extended, the pale areas consequently narrow and somewhat tinged with brown." 



The species was described from Nevada and has been taken at Wyoming and Colorado. 

 The early stages are unknown. 



11. Platyptilia pallidactyla Haworth, Lep. Brit.. 478, 1812. Primaries with nebulous 

 bright-brown and whitish markings. Cleft preceded by two brown dots. Pale areas a blotch in 

 cell, preceded by a brown dot, one near inner margin about one-third from base, and a broader 

 area below base of cleft. Lohes paler brown, crossed by a pale line outwardly and with a pale area 

 on costa above base of cleft, before which costa is narrowly dark brown, dotted with white. 

 All brown areas slightly irrorate with white. Secondaries brown. Fringes of inner margin of 

 third lobe with pale bases and usually with a faint cluster of slender dark scales just beyond
