Euplceinee (the Milkweed Butterflies) 
Segment. On reaching maturity the head is small, the body large, 
cylindrical, without hair, and conspicuously banded with dark 
stripes upon a lighter ground, and on some of the segments there 
are generally erect fleshy processes of considerable length (see 
Fig. 16). The caterpillars feed upon different species of the milk¬ 
weed (■ Asclepias). 
Chrysalis.— The chrysalis is relatively short and thick, rounded, 
with very few projections, tapers very rapidly over the posterior 
part of the abdomen, and is suspended by a long cremaster from 
a button of silk (see Fig. 24). The chrysalis is frequently orna¬ 
mented with golden or silver spots. 
This subfamily reaches its largest development in the tropical 
regions of Asia. Only one genus is represented in our fauna, 
the genus Anosia. 
Genus ANOSIA, Hubner 
Butterfly.— Large-sized butterflies; fore wings long, greatly 
produced at the apex, having a triangular outline, the outer mar¬ 
gin approximately as long as the inner 
margin; the costal border is regularly 
bowed; the outer border is slightly exca¬ 
vated, the outer angle rounded; the hind 
wings are well rounded, the costal border 
projecting just at the base, the inner mar¬ 
gin likewise projecting at the base and 
depressed so as to form a channel clasp¬ 
ing the abdomen. On the edge of the 
first median nervule of the male, about 
its middle, there is a scent-pouch covered 
with scales. 
Egg -—The egg is ovate conical, ribbed 
perpendicularly with many raised cross- 
lines between the ridges. The eggs are 
pale green in-color. 
Caterpillar.—'The caterpillar is cylin¬ 
drical, fleshy, transversely wrinkled, and has on the second tho¬ 
racic and eighth abdominal segment pairs of very long and slender 
fleshy filaments; the body is ornamented by dark bands upon a 
greenish-yellow ground-color; the filaments are black.
