median veinlets ; in one of the types is an additional spot situated between the radial vein and 
third median veinlet, and in the other type are two more spots, making four in all, which 
occupy the spaces between the second sub-costal and first median ; cilite alternately grey and 
white. 
Under surface greyish white; primaries pale ochraceous towards inner margin and pen- 
ciled with brown lines, the most decided of which are those nearest the costa ; the black spot 
or spots of upper surface repeated and pupiled with white. 
Secondaries, whole surface striated with brown of various depths' of color; the black 
spots of upper surface reproduced. 
Female. Expands 2 inches. 
Superiors broader in proportion than in male. 
Upper surface same color and ornamentation as male. 
Under surface likewise as in male but with a tendency in the linear markings of inferiors 
to form a mesial band. 
Habitat. Colorado. 
From the above description it will be seen that the two types have more sub-marginal 
spots on all wings than the one from which the accompanying figures were made ; this latter, 
along with many more of the same species, was taken in Colorado by Mr. Th. L. Mead in 
1871, the types were captured by Mr. Ridings, also in Colorado, in 1864. The fact ot these 
latter having three black spots on superiors and three and four on inferiors, is probably owing 
to local variation, as I believe all of Mr. Mead’s have but one spot on the superiors and two 
on inferiors, although some of the females have a minute or slight rudimentary third spot on 
the secondaries. 
Reakirt’s description of male and female was taken from two males, both of which are 
in my possession. 
This species bears on the upper surface a considerable resemblance to the Caucasian Ch. 
Tai’peia, Pall., but on the lower surface the resemblance almost altogether ceases.

Male. Expands If inches. 
Head and body grey. 
Upper surface ashy brown, primaries with a broad sub-marginal yellowish white band, 
separated where it is crossed by the second radial vein into two parts ; the one nearest the 
costa is palmated, being produced in four points outwardly, and has in the middle an oval 
black spot pupiled with white; the other is divided into three oblong portions by the crossing
