proceeding from little warts. Along the top of the back is a 
row of short black tufts, and on each side, from the fifth to 
the tenth ring inclusive, arc alternate tufts of orange and of 
yellow hairs, curving upwards so as nearly to conceal the 
black tufts between them ; below these, along the sides of the 
body, is a row of horizontal black tufts ; on the first and 
second rings are four long pencil-like black tufts extending 
over the head, on each side of the third ring is a similar black 
pencil, and two, which are white, placed in the same manner 
on the sides of the fourth and of the tenth rings. About the 
last of August, and during the month of September, these 
caterpillars leave the milk-weed, disperse, conceal themselves, 
and make their cocoons (Fig. 173), which mostly consist of 
hairs. The chrysalis (Fig. 174) 
is short, almost egg-shaped, being 
quite blunt and rounded at the 
hind end, and is covered with lit- 
tle punctures like those on the head of a thimble, only much 
smaller. The chrysalids are transformed to moths between 
the middle of June and the beginning of July. These moths, 
though not so slender as the Callimorphas, are not so thick 
and robust as the Arctias, their antenna) resemble those of 
the latter, but are rather longer, the feelers arc also longer, 
and spread apart from each other, and the tongue is but little 
longer than the head, when unrolled. The wings are rather 
long, thin, and delicate, of a bluish-gray color, paler on the 
front edge, and without spots ; the head, thorax, under side 
of the body, and the legs are also gray ; the neck is cream- 
colored ; the top of the abdomen bright Indian-yellow, with 
a row of black spots, and two rows on each side. It expands 
from one inch and three quarters to nearly two inches. This 
moth was figured and described many years ago by Drury, 
who named it Egle. Though marked and colored like some 
of the Arctias (for example, the luctifera of Europe), it 
cannot with propriety be included in the same genus, and 
therefore I have proposed to call it Euchcetes Eyle; the first 
Fig. 173. Fig. 174.
