274 CATERPILLARS AND THEIR MOTHS 



black face-lines and edge-lines, and the feet cream- 

 colored, with black at their base. The body was green, 

 with long sparse white hairs. The spiracles were 

 white encircled with blue-black, large, oval, and con- 

 spicuous. The anal plate and props were black, dotted 

 with white and edged with cream-color. The abdom- 

 inal props were green. The brown ones had the heads 

 brown, with darker lines ; the bodies brown, with a 

 dark dorsal line, and the sides darker than the back. 

 The legs and abdominal props were dark brown ; the 

 anal plate and props were shining black, dotted with 

 white and edged with light brown. There were long 

 white hairs. The spiracles were dark with a white 

 line, set in ovals of light brown, not as conspicuous as 

 those of the green one. 



On the thirtieth day they molted for the fifth time. 

 The horns and tubercles were less noticeable, as if 

 they had shrunk or the caterpillars had " grown up to 

 them." The green larva was dark bottle-green speckled 

 with lighter, and had fox-colored hairs. The brown 

 ones were as before. They ate well and grew to be 

 over three inches long, and stopped eating on the 

 fifty-first day. 



Usually the caterpillars are more to be noticed on 

 account of the horns on the thorax and their marked 

 anal props and shields than on account of their hairs, 

 but one year we found several green ones like the very 

 hairy one pictured. These looked so unlike the com- 

 mon ones that they seemed almost a different species, 

 or at least a variety. The photograph of this one is 

 perfect. The dark photograph is of a very dark brown 

 larva, more common than the green hairy form. 



Out of doors they burrow in the earth to pupate,
