parent form, from which it differs in that it has no spots on the upper or 

 under side of the primaries. Described from five specimens in the col- 

 lections of Am. Ent. Soc, Dr. Skinner and E. M. Aaron. 



AiitJiocharis genutia. — Rare. While this species has been taken at 

 Westville, N. J., five miles below Camden, by Messrs. Newman, Wilt and 

 Johnson at three or four difierent times in the past twenty years, we 

 have searched for it unsuccessfully for a number of seasons past, in April 

 and May, and have not succeeded until this season (May 6th) in captur- 

 ing it — two female specimens. These we found flying over banks on 

 which the white-flowered Cerastium arvense grew thickly. The food 

 plant. Sisymbrium thalianum, though usually not common, is found 

 there in considerable quantities. The locality is directly on the red clay 

 banks of the Delaware, just west of Westville, at the point where the 

 large shad nets are hauled in. 



Callidryas eiihide. — Exceedingly rare. Two or three specimens only 

 are known to have been taken. It is, however, common in the pine 

 barrens of South Jersey. 



Colias eurytlieme. — Very rare. The form Kee2i.iaydin\\'x% been taken 

 in a few instances. 



Colias philodice. — Common. 



Tej-ias nicippe. — Rare at Philadelphia, more plentiful below Camden, 

 N. J. The food plants, species of Cassia, are not common in this 

 locality. 



Terias lisa. — Moderately common, but very local. Feeds on false 

 sensitive plant (Cassia nictitans). 



Danias archippus. — Common. The caterpillar is usually infested 

 with a dipterous larva, perhaps Mascicera archippivora. In some cases 

 not one of a large number of caterpillars reaches the imago state. 



Agraulis vanillce. — Exceedingly rare. Probably only an occasional 

 visitant. It is possible that it has been brought here in one of its early 

 stages on its commonest southern food plant, Passiflora incarnata. 



Argynnis idalia. — Plentiful some years ; usually rare. On page 543 

 of his " Butterflies of the Eastern United States," Mr. Scudder states that 

 " the female generally flies a little faster than one can walk hurriedly. 

 The ample wings are flapped with great vigor, but do not seem adapted
