upon clover and other leguminous plants. And as this same 
species inhabits a district adjacent to us, it is a little remarkable 
that we never meet with it in Eastern New-York. Here all our 
specimens are of a pale yellow color, the tint of sulphur or of the 
canary bird, and pertain to the species named Phiiodice by Godart, 
which upon our side of the Atlantic occupies the place of the 
similarly colored Hyale, which is spread over the Old World, 
even to its easternmost confines, specimens of it having been sent 
me from Ningpo, China, by my friend Rev. M. S. Culbertson. 
Common with the Phiiodice, are individuals having the black 
border of both pairs of wings cut nearly or quite across by slender 
yellow lines which are the apices of the veins. These appear to 
be the Colias Chrysothome , var. A. of Boisduval, ( Lepidopteres, 
vol. i, p. 643,) which he intimates may be a distinct species, but 
which we are more inclined to regard as a variety of Phiiodice. 
Occasionally also, specimens are found with us, having the whole 
upper surface of the wings dusted over with black grains though 
less abundantly on the disk of the upper pair, and with the black 
border wider and somewhat gradually shaded into the yellow 
color of the disk. These appear to coincide with Boisduval’s 
description of C. phicomone, a species credited to the alpine dis¬ 
tricts of Europe and Siberia. Other- specimens, very similar to 
these, are a trifle smaller and have the knob of the antennae of a 
paler yellow, and brown on its upper side instead of black, and 
the yellow spots in the black border of the wings elliptic or oval 
instead of round. These I regard as the C. nastes of Boisduval, 
who received his specimens from Lapland and Labrador. In my 
collection is another New-York specimen much smaller than either 
of the foregoing, the wings expanding only one inch and a quarter. 
It is colored like Phiiodice , but the black border of the wings is much 
narrower, there is but a single silvery dot beneath in the centre 
of the lower pair, and the knob of the antennae is pale fulvous, 
somewhat mottled with browm on its upper side. This I have 
ticketed Colias santes in my collection. We thus have in addition 
to the Edusa, what some will regard as five species of the geuus 
colias, inhabiting the state of New-York. But these are all so very 
similar, and the several marks by which they are distinguished 
vary and gradually pass into each other to such an extent that it
