Genus Euchloe 
sara, except in being smaller, and having the margins of the hind 
wings marked with dark spots at the ends of the veins. 
(b) Variety Stella, Edwards, Plate XXXII, Fig. 35, 6 ; Fig. 
36, $ (Stella). The females of this form are prevalently yellow¬ 
ish on the upper side of the wings; otherwise they are marked 
exactly as the preceding variety. 
(c) Variety julia, Edwards, Plate XXXII, Fig. 34, 6 ; Plate 
XXXIV, Fig. 6, $, under side (julia). The only distinction in 
this form is the fact that the black bar dividing the red apical patch 
from the white on the remainder of the wing is broken, or tends 
to diminution at its middle. 
Early Stages. —Unknown. 
The species, in all its forms, belongs to the mountain States 
of the Pacific coast. Flora , Wright, is regarded by Beutenmtiller, 
who has given us the latest revision of the genus, as identical with 
sara. It comes nearer the variety reakirti than any other form, as 
will be seen by an examination of the plates which give figures of 
the types. Expanse, 1.25-1.75 inch. 
(2) Euchloe ausonides, Boisduval, Plate XXXII, Fig. 24, S ; 
Fig. 25, $ ; Plate XXXIV, Fig. 3, $ , under side (Ausonides). 
Butterfly. —On the underside the fore wings are greenish; the 
hind wings are marked with three irregular green bands, the 
outer one forking into six or seven branches toward the outer 
and inner margins. Expanse, 1.65-1.90 inch. 
Early Stages. —The larva and chrysalis are described by Ed¬ 
wards in “The Butterflies of North America,” vol. ii. The cater¬ 
pillar is pale whitish-green, with dark-green longitudinal stripes 
on the side and back. It feeds on cruciferous plants. 
Ausonides ranges from Arizona to Alaska, and eastward to 
Colorado. 
(3) Euchloe creusa, Doubleday and Hewitson, Plate XXXII, 
Fig. 23, .$ ; Plate XXXIV, Fig. 2, $, under side (Creusa). 
Butterfly. —Similar to the preceding species, but smaller, the 
white more lustrous on the under side, and the green markings 
on the under side of the wings heavier. Expanse,. 1.20-1.40 inch. 
Early Stages. —We know very little of these. 
The species is reported from California, Colorado, and Alberta. 
I possess a singular varietal form or aberration from Arizona, in 
which the black spot on the upper side of the primaries fills the 
outer half of the cell
