1. OIDZMATOPHORUS OCCIDENTALIS Walsinghain, Pter. Cal., Ore., 37, 1880. Primaries creamy 
white to deep ochreous, normally with a heavy brown costal mark over base of cleft, preceded 
and followed by a few whitish scales. This patch is counected with a small brown triangular 
shade before cleft. The wing is marked with cloudy brown areas and the first lobe is light 
brown. Fringes even tawny-grey. Secondaries brownish, shining with paler fringes. Expanse 
26-29 mm. Head with a pale patch between antennie, otherwise the darkest part. Thorax 
concolorous with primaries, paler behind. VPalpi rather small, oblique; second joint thickened, 
white-tipped. Front tibia with a heavy double tuft of brown scales in terminal half, mid-tibise 
with heavy median and terminal tufts of the same colour. Inner spur of median pair on hind 
tibie almost twice as long as outer. A very variable species. 
The records in British Columbia are from Kaslo (Cockle); Rossland (Danby); Vavenby 
(Moilliet) ; and a rather worn specimen from Fort Steele (W..B. Anderson). The type series 
was taken in California and it occurs in Arizona and Utah.

encroaching on first lobe. Costa with scattered dark-brown scales forming a long spot over 
base of cleft and two white dots beyond. Cleft preceded by a white area, and this by a davk- 
brown dash continued obliquely to costal spot by a light-brown shade. Sometimes a dark dot 
near middle of cell and some scattered patches of dark-brown irroration. Inner margin of first 
lobe with a brown dot belore apex, followed by a white pencil in the fringe. Fringes light 
brownish-grey with some white hairs. Secondaries brownish-grey. Expanse 21-27 mm. Hexd, 
thorax, and abdomen white. Palpi short, oblique, brown-speckled” Front tibixe with a large 
brown scale tuft; mid-tibie with two heavy brown tufts; hind legs white. 
Described from Vancouver Island. I have sot seen any specimens from the Island, although 
extensive collecting has been done on the southern portion of the Island, neither are there any 
specimens in the Bryant collection from Wellington. A short series was taken in August by 
Messrs. Day and Hanham on Mount McLean, and three specimens sent to me by Mr. Cockle, of 
Kaslo, as Petrophorus brucei Fern. turn out to be this species. Mr. Day records a specimen 
of this species taken by his son at Dawson, Yukon Territory, in 1910. It occurs in Southern 
California, and Barnes and Lindsey refer to this species specimens taken in Colorado and Maine 
which differ from typical specimens, but agree in all essential features. 
3. OIDAMATOPHORUS GRISESCENS Walsingham, Pter. Cal., Ore., 34, 1880. Primaries narrow, 
heavily sprinkled with white, and with some seattered blackish scales. Ground colour of inner 
half, brown; of costal half, apparently grey-brown, the scales tipped with white; but this area 
- . of the wing is greyish-white because of the predominating white scales. Costa with a grey-brown 
dash over base of cleft and two spots beyond. Cleft preceded by a white patch, and this by a 
small blackish spot curving forward to costal dash in a slender line. First lobe with a black 
dot before apex, followed by a white peucil in the fringes. Fringes brownish-grey with a mixture 
of white hairs. Secondaries grey-brown with concolorous fringes. Expanse 23-30 mm. Head 
and thorax clothed with grey-tipped white scales. Palpi short, oblique, each joint white-tipped. 
Abdomen whitish with brown-tipped scale tufts on posterior margins of segments.
