Eurynome
Butterfly, male.--The wings on the upper side are bright yellowish-fulvous, but little obscured at the base. The outer margins are edged by two fine lines which are occasionally confluent. The under side of the fore wings is pale buff, laved with cinnamon-brown at the base and along the nervules; the spots on the margin and in the apical area are well silvered. The hind wings on the under side are buff, with the basal and discal areas mottled with pale brown or pale olive-green. The marginal belt is broad and clear buff; all the spots are well silvered.
female.--The female is like the male, but paler, with the dark markings, especially those of the margin, heavier. The marginal spots inclosed by the lunules are much paler than the ground-color, and in many specimens almost white. On the under side the wings in this sex are like those of the male, but the fore wings are more heavily laved with cinnamon-brown at the base. Expanse, male, 1.70-2.00 inches; female, 2.00 inches.
Early Stages.--Mr. Edwards, in "The Butterflies of North America, "vol. ii, has given us a beautiful figure of the egg of this species. Of the other stages we have no knowledge.
A. eurynome is a very common butterfly in Colorado, Montana, and British America, and is the representative of a considerable group, to which the four preceding species belong, if, indeed, they are not local races or climatic varieties of eurynome, a fact which can be demonstrated only by the careful breeding of specimens from various localities. There is a fine field here for study and experiment.
