PAPILIO ANTICOSTIENSIS. 
11 
Secondaries have six yellow sub-marginal Iunules, the one nearest to anal angle much 
the smallest; also an inner band of seven yellow spots, the two nearest the costal mar- 
gin almost square, the next four oblong, and the last triangular; between these two macular 
bands is a row of spots composed of blue atoms; anal spot, deep fulvous, edged below with 
yellow, and contains a black pupil; emarginations yellow; tails one-fourtli of an inch in 
length. 
Under surface dark brown, ornamentation much as above ; outer row of spots on superiors 
larger than on upper side, paler in color, and more round in form; inner row pale fulvous, 
margined with light yellow; on secondaries the centres of the four outer spots between the 
costa and third median veinlet are fulvous; the spots comprising the inner band are also ful- 
vous, edged on inner sides with yellow ; a small yellow diseal spot ; space between outer and 
inner bands filled with greyish yellow scales, also a few blue ones nearest the inner band. 
Female. Expands 3| inches. 
The description of the male will apply almost equally well to the female, excepting that 
the ground color is not quite so dark, the inner bands are much broader and the black pupil 
in the anal eye, which is round in the former sex, is oblong in this ; the foregoing with the 
figure in the accompanying plate will, I trust, be sufficient for purposes of identification, for, 
after all, one good figure will do more towards determining a species than any quantity of 
written description however careful. 
Habitat. Fox Bay, Anticosti Island ; Labrador. 
For this species I am indebted to my valued friend Mr. Wm. Coupcr, of Montreal, who 
took several specimens of both sexes, whilst on a collecting tour last summer, ( 1872, ) in the above 
localities. He says : “ when I arrived at Fox Bay, Anticosti, last June it was extremely rare ; 
and I captured only four specimens in fifteen days, the specimens were fresh on the 20th of 
June, they generally flew low frequenting the flowers of a species of Wild Pea, which occurs 
abundantly on the banks of rivers in Anticosti and Labrador. I experienced great difficulty 
in approaching them with the net; its flight is rapid and low, extending along the margin of 
rocky cliffs and in grassy places near the Bay, near tide mark ; I never noticed them in the 
woods, they appeared to keep entirely within the circuit of the Bay and I remarked the same 
fact on the Labrador coast, where I also found them hovering about the flowers of the Wild 
Pea; towards the end of July their strength gives -way and if the weather be cool, tattered 
specimens may be taken by hand, it is the only species of Papilio, so far noticed by me, either 
in Anticosti or Labrador. ” 
When I received from friend Couper the box of Anticosti Lepid, my first impression as 
I glanced at its contents was that this species was Asterius and that both examples were males 
at that, but a closer examination soon convinced me to my surprise that the one with the most 
yellow was a female, I then thought it might be Saunder’s P. Brevicauda described in a foot 
note in Packard’s Guide to Entomology, page 246, but on consulting that publication, I 
found it did not agree with his description in several important particulars, in Brevicauda on 
upper side of primaries the spots composing the inner band, with the exception of the one 
nearest the costa are fulvous, in my species they are all yellow without the slightest indication 
of fulvous; on secondaries the spots of inner band are “ fulvous from near the middle to the 
outer edge,” in Anticostiensis these spots arc entirely yellow; the tails in Brevicauda, as its 
name would indicate are “ verv short, scarce! v one-eighth of an inch long — not more than 
half the length of those of Asterius in the species I have just described, they are the same
