PAP1LI0 X. 
Under side blackish brown ; the spots repeated, the sub-marginal enlarged, 
especially on primaries; the sub-apical area on costa of primaries largely dusted 
with yellow ; the middle of the black space between the band and the outer 
spots is also dusted, so as to form a band or stripe of scales; secondaries have 
the outer ends of the discal spots more or less suffused with yellow-fulvous, usu¬ 
ally only the tw r o or three spots next the end of cell, but sometimes all are so 
colored; the black extra-discal space is nearly occupied by clusters of yellow 
scales, on the anterior edges of which are clusters of blue scales. 
Body black ; on either side of the thorax a deep ochre-yellow stripe to the 
insertion of the wings; on the abdomen a sub-dorsal row of small yellow spots 
on either side, and another row which is lateral; there is also a lower lateral row 
from middle of the abdomen to last segment, and a vertical row of about the 
same length ; legs black, the outer side of the tibiae and tarsi buff; palpi yel¬ 
low and black; frontal hairs black, at the sides yellow ; on either side, between 
the eyes and back of the antennae, is a yellow spot; antennae and club black. 
Female. — Expands 4 inches. 
Upper side black-; the discal band represented by imperfect spots on both 
wings, corresponding to the outer portion of the spots of the male; there may 
be three or four of these on primaries, on the anterior part of the wing, or none 
at all; on secondaries, either a few small clusters of yellow scales, or nothing, 
except on costal margin, where there seems always to be a large and usually a 
distinct spot; all the yellow paler than in the males, rather buff; the clusters of 
blue scales sometimes large and conspicuous, sometimes obsolescent. 
On the under side the spots are generally more distinct, and on secondaries, in 
all individuals examined, form a complete series across the wing, but of single 
width, the spot in cell being obsolete in all cases; the spots are more suffused 
than in the male, either with dull fulvous or ochraceous, and the spots of sub¬ 
marginal row are often more or less fulvous; in some cases the extremity of the 
abdomen is yellow, and the central side largely so. 
This species inhabits Arizona, and probably Southern Colorado and Utah. The 
example described by me in 1866 was a male, which I found in a badly damaged 
state at the Smithsonian, and it was several years before other examples were 
received, taken in Arizona by the Wheeler Expedition. These were in bad 
condition and of little use for descriptions or figuring. Fortunately, Mr. B. 
Neumoegen received, in 1878, several fresh examples of both sexes, and has 
kindly allowed me to use them. The males differ much in the discal band, some 
having this of twice the breadth of others. In some the spots of this band are 
close together, in others there are wide black spaces between them ; all have
