wings, and reddish antenne. Their caterpillars are gen- 
erally green and smooth, and are found on the leaves of 
different species of the pea-tribe (/egumimose). 
The Corias Epvsa, of a yellow color, more or less mixed 
with green, is less common than the preceding species, but 
is found in some of the Middle States during spring and fall, 
and is identical with the Colias myrmidone of Europe. Its 
caterpillar is dark green, with a white line upon each side, 
and it lives upon clover. 
Corias CurysoTHEeME of New York, and Cottas Caso- 
NIA of the Southern States, are very little different from the 
former species. 
The genus Melitwa is distinguished from the preceding 
by their wings being spotted with red and black colors, so 
distributed as to make them look like a chess-board. Their 
caterpillars are covered with short, velvet-like hair. 
The Meuir©a Puarton (Fig. 48) is quite a handsome 
butterfly, but is un- 
fortunately very rare.

During many excur- 
sions in Rhode Island 
and New York, we 
have been able to find 
only a few of this spe- 
cies. 
The Merrrza Tua- 
Ros, of the Middle, and Merirma Ismerta, of the Southern 
States, are also not very common. 
The caterpillars of both genera, Colias and Melitwa, are 
both comparatively harmless, and we can not complain of 
much injury to vegetation being done by them. 
The genus Vanessa is much more common, and its larve 
much more numerous and rapacious. Its butterflies are 
distinguished by their velvet-like, denticulated wings, orna- 
mented with bright colors, and their long antenne. All
