220 ORDER LEPIDOPTEHA. 



inwardly by wavy lines of olive and flesh-color : outer half olive, but marked with 

 transverse abbreviated lines of darker. Apical area has a patch of flesh-color, but 

 branched so as to include a costal spot of olive : posterior margin olive, and the olive 

 marked with wavy bands. Hindwings marked with a row of submarginal olive spots. 

 The conspicuous dark olive spot near the body has been noticed : there are also al- 

 ternating abbreviated transverse lines of olive and flesh-color near the inner margin. 

 Beneath butf or fuscous, traversed by narrow bands or lines : posterior margin darker. 

 Expanse of wing about four inches. 

 This is not an uncommon species in New-York and Western Massachusetts. The larvse 



feed upn the grapevine, and hence Dr. Harris has given the generic name Philampelus, 



 I love the vine.' They also feed upon the Jimpelopsis. 

 The larva may be known by the recurved slender horn of the back when immature, 



but which is lost at the last moulting, leaving a smooth eyelike spot. Color pale green : 



sides marked with oval cream-colored spots. The head is retractile, which makes the insect 



appear shortened and blunt before. 



When mature, the insects are three inches in length : they are great feeders, and, when 



in numbers, injure vines in proporticm to the leaves consumed.
