Genus CEneis 
in the preceding species, and the transverse lines are more dis¬ 
tinctly marked. Expanse, 2.00-2.30 inches. 
Early Stages. —These have been most beautifully delineated by 
Edwards in the third volume of “The Butterflies of North America.” 
(3) CEneis macouni, Edwards, Plate XXVII, Fig. 3, $ 
(Macoun’s Arctic). 
Butterfly. —This species is closely allied to the two foregoing, 
but may be distinguished by the broad median band of dark brown 
traversing the under side of the hind wings, as well as by other 
peculiarities of marking. It 
lacks the bar of raised scales 
which is found in the male sex 
about the lower part of the cell 
of the fore wing in most of the 
species of the genus. It has 
been found thus far only on 
the north shore of Lake Su¬ 
perior and at the eastern base 
of the Rocky Mountains in 
the territory of Alberta. Ex¬ 
panse, 2.00-2.25 inches. 
Early Stages. — For a know¬ 
ledge of these in all their 
minute details the reader is 
again referred to the pages of 
the indefatigable Edwards. 
(4) CEneis chryxus, West- 
wood, Plate XXVII, Fig. 10, 6 
(The Chryxus Butterfly). 
Butterfly .—This species is widely distributed, being found in 
Colorado, British Columbia, and the vicinity of Hudson Bay. It 
is distinguished from other species by the darker brown color, 
which covers the basal and median areas of both the fore and 
hind wings, leaving a broad band of lighter brown on the outer 
margin. On the under side the wings are beautifully mottled 
with white and dark brown. CEneis Calais , Scudder, is prob¬ 
ably only a form of chryxus, which is somewhat lighter in color 
on the base of the wings. Expanse, 1.60-1.75 inch. 
Early Stages .—The life-history is fully recorded in the pages 
3f Edwards.
