THE STUDY OF INSECTS 



(Fig. 434) measures from 3 to 4 inches in length. It is thinly clothed 

 with long hairs, and bears prominent spiny horns on the second and third 

 thoracic segments. Jn the early larval stages these thoracic horns are 

 very long and spiny, resembling those of the larva of the regal-moth.

The larva feeds on hickory, pine, oak, butternut, and other forest trees. 



The two-colored royal -moth, Adeloccphala blcolor. — In this species 

 the upper side of the fore wings and the underside of the hind wings are 

 yellowish-brown, speckled with black. The underside of the fore wings 

 and the upper side of the hind wings are to a considerable extent pink. 

 There is usually a dark discal spot on the fore wings, upon which, es- 

 pecially in the males, there may be two white dots. This species is more 

 common in the South than in the North. The expanse of wings in the 

 male is 2 inches; in the female, 2§ inches. The larva feeds on the leaves 

 of the honey-locust and of the Kentucky coffee-tree. 



The rosy-striped oak-worm, Anisota virginiensis. ■ — The wings of the 

 female are purplish-red, blended with ochre-yellow; they are very thinly

scaled, and consequently almost transparent; and are not speckled with 

 small dark spots (Fig. 435). The wings of the male are purplish-brown, 

 with a large transparent space on the middle (Fig. 436). The larva is of 

 an obscure gray or greenish color, with dull brownish-yellow or rosy 

 stripes, and with its skin rough with small white warts. There is a row of 

 short spines on each segment, and two long spines on the mesothorax. 



The orange-striped oak-worm, Anisota senatoria. — The wings of the 

 female are more thickly scaled than in the preceding species and are 

 sprinkled with numerous blackish dots; in other respects the two are 

 quite similar in coloring. The male differs from that of A. virginiensis in
