Four New Additions to Our Local List of Rhopalocera 



By F. E. Watson, New York. 



Argynnis aphrodite, var. alcestis, Edw. 



One fine female of this variety was taken by the writer in 

 Van Cortlandt Park, New York City, July 16, 1900. The speci- 

 men was captured in the hilly section of the park. 



This individual agrees with typical specimens of alcestis from 

 Illinois and Minnesota in the writer's collection and also agrees with 

 the figures and description in Edward's "Butterflies of North 

 America." 



Through the kindness of Mr. Wm. P. Comstock this specimen 

 was taken to Philadelphia and shown to Dr. Skinner, who pro- 

 nounced it an average specimen of alcestis. I wish to express my 

 thanks to Dr. Skinner and Mr. Comstock for their assistance in 

 establishing this record. 



Basilarchia archippus, var. lanthanis, Cook & Watson 



One male captured Aug. 13, 1911 at Athenia, N. J., and one 

 male June 23, 1912, at Pearl River, N. Y., by the writer. This is a 

 biological variety* and should not be confused with the aber- 

 rant pseudodonpptis of Strecker. 



These two forms ha\'e one character common, viz. : the 

 extramesial black stripe on the upper side of the secondaries being 

 obsolete . 



Tachyris margarita Hiib. (ilaire, Godart) 



Two specimens were seen and one captured June 10, 1906, 

 at Canarsie, Long Island, by Mr. Otto Mayer, in a field containing 

 an occasional patch of scrub and partly hemmed in with truck 

 gardens. The one captured was on blackberry blossoms.
