middle. Expanse 21-26 mm. Frontal tuft about as long as head, sharply pointed. Palpi long, 

 slender, porrect, noticeably surpassing tuft. 



Our British Columbia specimens agree with the above description, excepting in the faint 

 cluster of slender dark scales on the inner margin of third lobe. In all the specimens I have 

 examined the cluster is absent, but in most of the specimens there are a few scattered dark 

 scales, mostly in the basal half. I have it from Victoria (Carter); Coldstream (Day and 

 Blackmore) ; Vernon (Ruhmann) ; and Kaslo (Cockle). I found it not uncommon at Gold- 

 stream in June. It apparently ranges over the entire North American Continent north of 

 37° latitude, and also occurs in Europe. 



12. Platyptilia albert.e Barnes and Lindsey, Cont. Lep. No. Amer., Vol. IV., No. 4, 34G, 

 Aug., 1021. Primaries white. Costa narrowly brownish-grey to cleft. Cleft preceded by two 

 dark dots; a third similar dot in middle of cell. Lobes with terminal and median greyish 

 shades defining the broad outer white line. Fringes white, basal scales on outer margin white. 

 Secondaries very light brownish-grey, fringes and third lobe paler. Expanse 24-27 mm. 



The shape of the primaries is distinctive. Towards the apex the costa is abruptly rounded, 

 the apex is very blunt, and the outer margin of the first lobe almost straight. The first lobe 

 and consequently the entire wing looks very wide and blunt. Frontal tuft as long as head, 

 sharply pointed. Palpi moderate, oblique surpassing front, but not reaching end of tuft. 



The species was described from four specimens, as follows: Ilolotype female, Laggan, Alta., 

 August 16th to 23rd, and one paratype female, Olympic Mountains, Wash., in Coll. Barnes. 

 Allotype male, Mount Cheam, B.C., August, in Coll. Blackmore. Paratype female, Laggan, Alta., 

 August 16th to 23rd, in U.S. National Museum. 



The Mount Cheam specimen was taken by the late Captain R. V. Harvey in August. 1903. 

 Among some material sent by Mr. Cockle, of Kaslo, for examination were two specimens of 

 this new species. Both of them are rather worn and one is without abdomen ; the latter, 

 presumably taken at Kaslo, is without date. The other specimen was taken at Sandon on 

 August 9th, 1904. 



Unfortunately the wings have a tendency to stain easily and in the allotype they are more 

 or less tawny. It is evidently a high-altitude species. 



Genus STENOPTILIA Huebner. 

 Stenoptilia Huebner, Verz. bek. Schmett., 430, 1S26. Front with a rounded or conical 

 prominence or a scale-tuft. Ocelli present. Palpi various. Primaries bifid, cleft from about 

 two-thirds. Secondaries trifid, third feather without dark scales iu fringes of inner margin. 

 Anal angles of both lobes of primaries very retreating. Very closely allied to the preceding 

 genus, but can be separated from the greater part of Platyptilia by the lack of dark scales in 

 the fringes of the secondaries and from the remainder by the retreating anal angles. 



1. Stenoptilia mengeli Fernald, I'ter. No. Amer., 60, 1S9S. Primaries ashy-grey and glisten- 

 ing; a few dark fuscous scales on the first lobe form an ill-defined longitudinal stripe on the 

 middle; a fuscous spot at the end of the cleft. Hind wings ashy-grey. Expanse 20 mm. 

 Thorax and palpi dark ashy-grey. A fine white line occurs over each eye. 



A single specimen taken by Mr. A. W. Hanham on Mount McLean in August constitutes our 

 only record. It is a rather surprising capture, as very few specimens are known. It was 

 described from ten poor specimens taken by Mr. W. L. Mengel at McCormack's Bay. North 

 Greenland in 1891. Barnes and Lindsey record a single specimen from Colorado which is slightly 

 paler than the types. The latter specimen is in the U.S. National Museum. This is apparently 

 all that are known. 



2. Stenoptilia exclamationis Walsingham, Peer. Cal., Ore., 32, 1880. 

 Stenoptilia coloradensis Fernald, I'ter. No. Amer., 61, 1898. 



Primaries dark brownish-grey on costa, blending into ochreous or pale grey on inner margin, 

 and irrorate with white in most specimens. The white scales are heaviest on the terminal area 

 of both lobes. Cleft preceded by two blackish dots, usually fused. First lobe with a heavy 

 blackish shade, margined outwardly with white and preceded on costa by a white dash. There 

 is usually a blackish dot near middle of cell. Fringes white in cleft, with greyish clusters before 

 outer margin, elsewhere grey, white below apices of both lobes. Secondaries brownish-grey with 

 'concolorus fringes. Expanses, 18-24 mm. (British Columbia examples are more consistent in 

 size, measuring 22 mm.) Palpi moderate, whitish above; third joint small; a white line over 

 each eye.
