radian summits, while the other species of this genus, C. chryxus and C. TJhlerii , 
both ochraceous, are found below. 
I do not know why Smintheus has been assumed to be a variety of Phoebus, as 
there is no close resemblance between the species, not so much in fact as between 
Smintheus and Jacquemontii, Bois. Phoebus is larger, of a more opaque white, with 
a tendency in the males to yellow; the transparent marginal space is far broader 
and longer than in Smintheus, and is wanting in the white serrations that charac- 
terize the marginal edge in the latter; the grey sub-apical stripe in Phoebus reaches 
hut a little way from costa, usually only to first discoidal nervule; in Smintheus it 
is of all lengths and frequently extends quite across the wing; in Phoebus the margin 
of secondaries is immaculate; in Smintheus there are almost always at least traces 
of submarginal spots on the under side, and more often conspicuous spots on both, 
reaching the extreme shown in var. Behrii; the red spots in Phoebus average twice 
the size of those in Smintheus, and those at base of secondaries, in both sexes, are 
both large and intense; in Smintheus they are small, much replaced by black 
and ofteu wanting altogether or represented by a few scales only; the fringes in 
Phoebus are mixed black and white at the ends of the nervules, the black not dis- 
tinct; in Smintheus they are there largely and distinctly black; the body of Phoebus 
is densely covered with long hair, in Smintheus very thinly. 
As to the females the differences are still greater and almost preclude com- 
parison. Except in the presence of red on primaries, the female Phoebus is much 
more like that of Apollo .

Purnassius Eversmanni , Menetries, Enum. Corp. Aaim. Mus. St. Petersburg, Part I, pi. 1, 1865. Scud- 
der, Proc. Bost. Soc. Nat. Hist. 1869, 
Male. — Expands 2.5 inches. 
Upper side citron yellow, the nervures black and prominent; primaries have 
a broad, semi-transparent marginal border, preceded by a row of yellow lunules; 
next anterior to these a grey stripe reaching from costa to a little below median ner- 
vure, and followed by a broad yellow band completely crossing the wing; anterior 
to this is a second grey stripe and a second yellow band that passes around the end 
and lower side of cell; both these bands divided into spots by the nervules; in the 
cell two sub-quadrate yellow spots separated by a grey bar; a similar bar on arc; 
base of cell and costa throughout sprinkled with black; the hind margin distinctly 
edged by a yellow line. Secondaries have an obsolete sub-marginal row of grey
