290 CATERPILLARS AND THEIR MOTHS 



them on the maple-trees, two or three on a leaf, and 

 fifteen or twenty on the five or six leaves nearest the 

 first we found. 



They are very pretty caterpillars, and are very 

 dainty, refusing leaves not absolutely fresh, and by no 

 means willing to eat any kind of maple which may be 

 most convenient. We had to walk a mile and a quar- 

 ter to get leaves which suited this brood, and to go as 

 often as every second day, too, and then they refused 

 the leaves from the older tree, and would eat only 

 those from saplings, which do not keep fresh as long 

 as tree-leaves, even after soaking their twigs. 



The pupae were small, dull black, rough with spines 

 on the edges of the abdominal segments. 



The moths are beautiful. They have pale yellow 

 bodies and pink, "furry" legs. The fore wings are 

 pink at the base and apex, with a triangular patch of 

 pale yellow between the two pink areas. The hind 

 wings are yellow at base, shading into pink. The 

 yellow is the pale yellow of primroses. The male's 

 antennae are pectinate on the lower half, simple the 

 rest of their length. The female's are simple.
