LETTEES FROM ALABAMA.

the first wings ; the second pair has a large cloud 
of azure dots in the centre. The under surface is 
much the same, but the black is more dusky ; the 
crescents in the second wings are larger and tinged 
with orange, and the azure central cloud is want- 
ing. It appears to be rare, as I have seen only 
two specimens of it, but one of which I succeeded 
in obtaining. This I caught in a garden just as 
the sun was setting, hovering over a strawberry- 
bed ; the other was seen in the middle of the day, 
but in the dark shade of the woods ; I gave chase 
to it, but it redoubled its speed, and was soon out 
of reach in the forest. I observed that it flew high, 
which butterflies do not generally do. The larva 
of this fine species is said to be in all respects like 
that of the Tiger Swallow-tail [Papilio Turnus)^ 
being of a fine green, with two eye-spots on the 
thickest parts of the body. 
I have taken a single individual, in very shabby, 
weather-beaten condition, of another fine butterfly, 
the Eed-spotted Purple {Limenitis Ursula). It is 
black, or rather a very deep purple, the hind-wings 
broadly banded with lustrous bluish-green, and 
marked with crescents of the same. The under 
surface, besides, has many spots of bright red. It 
very much resembles the Banded Purple of the 
north {Limenitis Arihemis)^ but it wants the deli- 
cate pearly- white band. It seems to replace that 
species in the south. The larva and pupa have a 
still more exact resemblance ; the former is said to 
feed on the Green-wooded Whortleberry {Vacci- 
nium stamineum). ‘ 
And, while speaking of insects, I may just men- 
tion two or three others that I have recently seen, 
though I know little of them but their appearance.
