THE ARCHIPPUS BUTTERFLY.

fourteen clays, during wliicli it changes its skin three times, 
and finally attains to the length of nearly two inches. The 
chrysalis is about an inch long, but very thick, nearly cylin- 
drical in the middle, and rounded at each end, with a very 
slender black point, by which it is suspended. Its skin is 
exceedingly thin and delicate, of a light green color, and 
ornamented with golden spots and a transverse stripe of 
black and gold. The chrysalis state lasts ten or twelve days, 
at the expiration of which the butterfly comes forth. The 
Archippus butterfly is very common on flowers, particularly 
on low lands, from the middle of .Tuly to the first of Sep- 
tember. The wings on the upper side are tawny orange, on 
the under side deep nankin-yellow ; they are surrounded by 
a black border spotted with white ; the veins are black, and 
there are several yellow and white spots on the black tips of 
the fore wings. The males are distinguished by an elevated 
black spot contiguous to one of the veins near the middle of 
the hind wings. This butterfly measures across the wings 
from 35 to 4£ inches. The antennae in the genus Danais 
have a long and curved knob ; the head and thorax are 
spotted with white ; the males have an elevated spot near the 
middle of the hind wings, which in both sexes are rounded, 
and never tailed or indented. The caterpillars are furnished 
with projecting thread-like horns in pairs, and the chrysalids 
are short and thick, somewhat oval, and arc ornamented with 
golden spots. The other characters of the genus are the 
same as those of the division to which it belongs. 
We have another four-footed butterfly which closely re- 
sembles the Archippus in color and markings, but differs from 
it entirely in the chrysalis and caterpillar state. It is the 
Disippe butterfly ( Nymphalis Ditsippe* of Godart). (Fig. 
109.) It is of a tawny yellow above, and of a paler yellow 
beneath, the wings are surrounded by a broad black border 
spotted with white, the veins are black, there is a triangular 
patch spotted with white near the tips of the fore wings, and 
* This is the Misippus of Fabricius, but not of Linnaeus.
