SUPPLEMENTARY NOTES. 



branch of mediaa nervure, each spot posteriorly and at the edge of the margin 

 being orange; abdominal margin orange tinted. 



Under side yellow; j^rimaries 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 EuKYTHEME. — From Mr. Hayhurst 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 j^ilose, each segment transversely creased; a narrow white lateral band 

 from second to last segment, through the middle of which runs a broken line of 

 vermillioa red. This larva is a little longer and larger than that of 0. Pldlodice, 

 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 jjoint ^posteriorly ; the head case also i^roduced 

 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 Philodicc, in the attenuation of the head case and lesser prominence of the 

 process; also in absence of the abdominal markings. This descrij^tion 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 loth, when 

 four males were taken near the South Park; elevation 9000 feet. On 21st, at 

 Turkey Creek Junction, 27 S and 7 2 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. Konopickv. 

 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. 



Argyxnis Diaxa. — 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 veiy attractive to 

 all butterflies. But it is only upon such patches of this plant as are near the
