THE ARCHIPPUS BUTTERFLY. 281 



fourteen days, during which 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 July 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 3f to 4| inches. The antennse in the genus Danais 

 have a long and curved knob ; the head and thorax arc 

 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 are 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 Disippe* 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 3f(s/j>j)iis of Fubricius, but not of Linnaeus.
