TAPILIO ASTERIODES. 49 



The third is a heniuipiiroditc, taken by Prof. J. E. Meyer in Brooklyn, in 1863, now in 

 possession of Mr. \V. 11. Edwards, who described it in Proc. J"nt. Soc., Phil., lY, p. 390, 

 both the right wings are male and the left ones female, with no suifnsion or mixing of color. 



Since describing P. Anticostiensis on page 10, Mr. Couper has made another entomo- 

 logical tour to the Island of Anticosti, and, among other results of his most commendable 

 enterprise, are some forty specimens of this species, taken at Ellis Bay, about 117 miles west 

 of Fox Bay, where he took the types figured on plate II. I have examined twelve of these, 

 male and female, and find they agree with the types and appear to be subject to scarcely any 

 variation, except in the length of the tail, which varies in different examples from 3-lG lo 

 5-16 of an inch; the size of this appendage is, however, valueless for specific purposes, as in 

 P. Philenor it is found from ^ to ^ of an inch, in P. Agamemnon from a mere tooth to nearly 

 2 of an inch, in P. Pammon from } to } of an inch, and the same difference in length occurs 

 in many others. 



Mr. Couper also secured the egg and larva ; the former, he states, " are laid singly on the 

 leaves of Archangelica Atropurpurca which occurs common throughout the whole extent of 

 the Island; the egg is spherical and pale yellow." The larva, which I will figure on mv 

 next plate of diurnals, is pale green with a transverse row of black spots or dashes on each 

 segment, the lateral ones running obliquely; from these spots emanate little points; unfortu- 

 nately, Mr. Couper could not sojourn on the island long enough to obtain the fully matured 

 larva; the one just described is | of an inch long. Mr. Couper also took at Anticosti this 

 summer a dozen examples of Colias which will doubtless tend to increase the muddle into 

 which that interesting genus has been thrown through the indefatigable labors of our lepidop- 

 terists.

(PLATE VI, FIG. 5, (^.\ 



Expands 1| inches. 



Antennae white, club black, tipped with white at extremity ; head and body black above, 

 beneath white. 



Upper surface white ; primaries, some black scales at base ; a broken black or dark 

 brown apical patch, varying in extent in different examples, but in none that I have seen is it 

 as heavy as in A. Ansonides ; a black diseal spot. In the secondaries the marbleing of under 

 surface is partially visible ; some black at base as in primaries. 



Under surface white ; primaries, some fine brown reticulations near the anterior angle ; 

 diseal spot black.
