LEP1D0PTERA. 
3*7 
larger specimens expanding less than one inch and a half. 
The wings are canary-yellow above, with the apex of the 
fore wing and the outer margin of both fore and hind wings 
blackish brown. The border of the hind wing is narrow and 
sometimes wanting. 
The distribution of this species is similar to that of the 
preceding. The larva feeds on Cassia. 
The Dainty Sulphur, Nat kalis iole (Na-tha'lis i'o-le).— 
This little butterfly can be distinguished from all others de¬ 
scribed here by its small size, as it expands only from less 
than one inch to one and one fifth inches. It is of a pale 
canary-yellow color, with dark brown markings. There is a 
large apical patch on the fore wings, and a broad band par¬ 
allel with the inner margin ; on the hind wings there is a 
stripe on the basal two thirds of the costa, and spots on the 
ends of the veins; these are more or less connected on the 
margin of the wing, especially in the female. 
This species also is found from Southern New England 
to Florida and west to Lower California. It, too, feeds on 
Cassia. 
The Cloudless Sulphur, Callidryas eubule (Cal-lid'ry-as 
eu-bu'le). — This large butterfly differs greatly in appearance 
from those described above. It expands two and one half 
inches. The wings above are of uniform bright canary- 
yellow. In the male they are without spots, except fre¬ 
quently an inconspicuous brown dot at the tip of each vein, 
and a lilac-brown edging of the costal border. In the 
female there is a discal dot on the fore wing and a mar¬ 
ginal row of brown spots at the ends of the veins. 
This is a southern species which occasionally extends as 
far north on the coast as New York City, and in the Missis¬ 
sippi Valley as far as Southern Wisconsin. The larva feeds 
on Cassia.
