the lack of any trace of the warm brown shades so evident in the colour- 
ing of that species. 
The differences are not easily expressed in words; but the insects 
when placed side by side can be distinguished quite readily. 
The types of this species are four specimens collected by Mr. 
Theodore Bryant near the Taku River in northern British Columbia. 
They were all taken in July and August 1906. These are all in my own 
cabinet; but there are other specimens in the collection of Mr. Bryant. 
I have also a specimen, nearly resembling the above and which may 
belong to the same species, which was captured at Victoria by Mr. A. 
W. Hanham. It is not in sufficiently good condition for me to be quite 
sure of its specific status. 
Entephria lagganata, n. sp. 
This is a,fourth American species of this group. The markings 
are similar to those of the other species mentioned; but in lagganata 
the cross lines are all of them very fine, and the central and submarginal 
areas appear very little darker than the rest of the fore wing. The 
markings are of a pale yellowish brown shade very different from the 
dark blue gray of takuata or mullivagata, or the bright brown of 
cesiata. The discal spots on the hind wings are very inconspicuous. 
I have four specimens of this species. Of these, three were taken 
at Laggan, Alberta, on the, 8th of August, 1900, at altitudes ranging 
from 5,700 to 7,000 feet. The fourth specimen was taken on Sulphur 
Mountain near Banff, Alberta, on 12th August, 1900, at an altitude 
of nearly 8,000 feet. 
The captor in each case was my good friend Mr. F. H. Wolley-Dod, 
of Calgary, from whom I have received very many valuable specimens. 
There are two specimens in the collection of the U. $. National 
Museum labelled “ Colorado,” which should probably be referred to 
lagganata. Mr. L. B. Prout, of London, England, in a recent com- 
munication informs me that this species resembles somewhat closely 
the rare “ Larentia ravaria” of Lederer from the Altai Mountains, a 
species I have had no opportunity of seeing. 
Rachela pulchraria, n.sp. * 
This is decidedly the most beautiful species of the genus yet dis- 
covered. It is of the size of R. occidentulis and the style of the mark- 
ings is the same, but it is well distinguished by the antennal structure 
and by its very different colouring. 
Expanse 33 mm.
