(PLATE VI, FIG. 1 cT, 2 $.) 
Male. Expands 3| to 5 J inches. 
An ten me black, body yellow with a broad black dorsal, and narrow lateral and ventral 
bands. 
Upper surface chronic yellow; primaries with six transverse black bands, all of which, 
with the exception of the marginal, are very narrow ; first, is basal ; second extends from 
costal to interior margin ; third from costa to first median veinlet; fourth along the disco- 
cellular veins, from third sub-costal veinlet to second radial vein ; fifth terminates in some 
scattered atoms at the second radial veinlet ; sixth, broad, extending along the whole of the 
exterior margin and divided transversely by a row of almost confluent yellow lunules. 
Secondaries have the basal and second black bands of primaries continued to near the 
anal spot, where they are united; a broad marginal band, with six large crescents, the one 
nearest the anal angle fulvous, the others yellow, more or less tinged with fulvous; anal spot, 
which is also fulvous, is surmounted by a blue crescent, some patches of blue scales on the 
border, interior to the sub-marginal lunules; four tails, the outer and innermost of which are 
the shortest, that next the outermost is longest, and the remaining one is half the length of 
this latter ; enjargi nations yellow. 
Under surface much paler; primaries marked as on upper surface, except that the sub- 
marginal lunules are replaced by a broad yellow band. 
Secondaries have the sub-marginal lunules, which arc, with the exception of the two 
nearest the anal angle, larger than above, succeeded by yellowish grey atoms, edged interiorly 
with shining blue, which is surmounted with black, adjoining which, between the abdominal 
margin and second sub-costal veinlet, are five triangular rufous spots or flames; di seal arc 
black; second and third median veinlets edged with black scales. 
Female same as male, but all the markings are much heavier, and, on upper surface, not 
so intensely black as in the male. 
Habitat. Colorado, Kansas, Mexico, Guatemala, 
The above description of this superb species applies more particularly to the tropical 
form, found in Mexico and Central America ; the examples from Colorado present some few 
points of difference in the male, in that the third and fourth transverse bands of primaries do 
not extend beyond the median vein, aud the fifth is almost obsolete ; on secondaries the lunule 
nearest the anal angle is the only one that is fulvous, and there are no red flames on the under 
surface. 
Mr. Ridings, who, in 18G4, took several of this species in the Rocky Mountains, says it
