Euploeinae (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 {Asclepms). 



Chrysalis.— l\\e 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 Aiiosia. 



Genus ANOSIA, Hubner 



Butterfly.— LsLVge-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. 



£^;^.— 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.
