The micler surface has two scarlet spots, and a 
band of the same colour. The larvajs said to feed 
on the Swamp Papaw (Anona palustris). The 
chrysalis is short and thick, shaped almost like the 
body of a pig, with a sharp thorax. Its colour is 
dusky brown, with pale lines. 
And there are no less than three species of Colias^ 
all pretty : one is of a bright saffron-yellow, with a 
common black border, unspotted — the Black-bor- 
dered Yellow [C. Nicippe). This is numerous in 
gardens, particularly in the morning. That large 
one now resting on a flower, opening its brilliant 
wings to the sun, is the Black-based Yellow 
[C, Goesonia), It is a strikingly-marked species, 
the sulphur-yellow contrasting well with the broad 
border and basal cloud of deep black. Each wing 
has a silvery spot in the centre of the under sur» 
face, on which side the black is altogether wanting. 
And this pigmy, whose wdngs are scarcely more 
than half an inch in length, is the Black-banded 
Yellow {C, Diara ) ; it is of the same sulphur-yellow 
as the last, with a black tip, and a broad band of 
the same running along parallel to the inner margin 
of the fore wings. The caterpillars of these butter- 
flies have generally much resemblance to each 
other, being green, with white or yellow stripes ; 
and the chrysalids, which in this genus are sus- 
pended by a girdle of silk around the thorax, as 
well as by the anal button, are like the larvm in 
colour. 
But we will go on look at that conspicuous tree 
standing out from the edge of the woods just at the 
corner of two roads. It is a blasted chestnut ; its 
bark has long fallen off, and left its limbs to bleach 
and dry in the summer sun. On the very topmost
