SUPPLEMENTARY NOTES. 
branch of median nervure, each spot posteriorly and at the edge of the margin 
being orange; abdominal margin orange tinted. 
Under side yellow; primaries marked as above, but secondaries have- all the 
nervures broadly bordered with black scales, which, beyond the disk, nearly fill 
the interspaces; the black marginal band as above, the spots smaller; an orange 
patch on edge of margin in each interspace; costal and abdominal margin orange. 
Colias Eurytheme. — From Mr. Hay hurst I have received 'an admirably 
executed drawing of the egg, larva and chrysalis of this species. The egg is long, 
fusiform, ribbed longitudinally. Length of mature larva 1.4 inch; cylindrical, 
tapering posteriorly from 11th segment; head green, translucent; body dark green, 
somewhat pilose, each segment transversely creased; a narrow white lateral band 
from second to last segment, through the middle of which runs a broken line of 
Vermillion red. This larva is a little longer and larger than that of O. Philodice, 
which it much resembles, but is without the series of semi-circular black spots next 
under the lateral band, usually seen on the latter. The eggs were deposited on 
Buffalo Grass, (Trifolium reflexum) and the larvae fed thereon. Chrysalis .95 inch 
in length; cylindrical, tapering to a point posteriorly; the head case also produced 
to a point; mesonotal process rounded and not very prominent; a whitish lateral 
line runs from wing cases to extremity of abdomen, above which is a black stripe 
that crosses two or three of the upper abdominal segments. The shape differs from 
that of Philodice, in the attenuation of the head case and lesser prominence of the 
process; also in absence of the abdominal markings. This description however is 
given from the drawing. 
Colias Alexandra. — This species was found by Mr. Mead to be very com- 
mon in certain localities in Colorado. “It was first observed about June 15th, when 
four males were taken near the South Park; elevation 9000 feet. On 21st, at 
Turkey Creek Junction, 27 $ and 7 $ were taken, all in fine condition. But one 
or two of the females were albinos, this variety being exceedingly rare. The last 
Alexandra was taken August 28th. The eggs were laid upon Lupinus.” 
From an egg sent me, a magnified drawing has been made by Mr. Konopicky. 
The shape is fusiform, like that of egg of Eurytheme, and it is longitudinally fur- 
nished with 18 or 20 ribs, between which throughout are transverse ribs of less 
prominence. 
Argynnis Diana. — This butterfly continues to be the rarest of its genus. 
A few individuals appear about the first day of July, in Kanawha, when the 
milk-weeds (Asclepia) are in bloom, the flowers of which are very attractive to 
all butterflies. But it is only upon such patches of this plant as are near the
