162 CATERPILLARS AND THEIR MOTHS 



We have found but few hylcBus caterpillars, and ink- 

 berry and Prinos of the other species were the only 

 food-plants they would eat. Probably others will be 

 discovered some day, though the coloring of the cater- 

 pillars fits them for the inkberry better than for any 

 other plant. 



Like most sphingid caterpillars, when half and full 

 grown they rest on the twig under the leaves. Seen 

 from above they are inconspicuous, because the venter 

 and sides, which are uppermost, are of just the color 

 of the upper surface of the leaves. When the twig is 

 turned over they are equally inconspicuous, because 

 the dorsum is of just the white-green of the under side 

 of the leaves, while the outline of the caterpillar is 

 broken by blue-purple like the berries and pink like 

 the buds. 



The moths are rust-brown, black, and white, the 

 brown varying much in shade, being sometimes pale 

 ocher-brown, sometimes pale chestnut-brown, at others 

 very red-brown. The fore wings have a rich, velvety 

 look, are crossed by wavy lines of black and white, 

 and have a distinct discal dot on each. The hind 

 wings are smoky white at base, almost black at the 

 outer margin, and crossed by a black band, or by two 

 black bands, more or less distinct. The thorax is 

 brown mottled with black, the abdomen brown, with 

 black and white spots and bars, the ventral surface 

 being white. 



The under side of the wings is coffee-brown, with 

 darker brown margin and wavy lines of darker brown 

 and white. The antennae are ciliate in the male, sim-
