 weed. 



Vanessa cardui (Linne) has been with us again this season but 

 was scarce.

Pieris napi virginiensis Edwards. 



Following the Barnes and McDunnough Check List of Lepidoptera, 

 1917, this butterfly is here given as a race of Pieris napi (Linne). 

 I am inclined to think that this may be a distinct species, for among 

 other things, it seems to have but one generation a year, napi oleracea 

 (Harris), the more northern insect, having two. 



The name virginiensis has not heretofore appeared in any of our 

 local lists, specimens recorded as napi (Linne) or oleracea (Harris) 

 are probably of this form. As this is a very rare butterfly in the 

 vicinity of New York City, records from the following specimens, 

 which I have examined, may be of value. 



Good figures of virginiensis are given by W. H. Edwards in his 

 Butterflies of North America, Vol. I, 1871, PI. IX, Figs. 5-8. 



One female, in fair condition, Paterson, Passaic County, New Jersey, 

 May 6 (J. A. Grossbeck) ; in the collection of The American Museum 

 of Natural History. This specimen is recorded as "P. oleracea 

 Bdv." on p. 417 of Report New Jersey State Museum — Insects of 

 New Jersey (1909), 1910, by J. B. Smith. It was probably taken 

 in the vicinity of Garrett Rock (Watchung Mountains). 



One female, in poor condition, Watchung Mountains, New Jersey, 

 May 6, 1900 (W. D. Kearfott) ; in the collection of The American 

 Museum of Natural History. A pencil label attached to the speci- 

 men says " Garrett Rock," so that this individual was probably 

 captured in the same general region where the preceding and follow- 

 ing butterflies were taken. 



One male, in good condition, Watchung Mountains, between Pater- 

 son and Great Notch, Passaic County, New Jersey, April 30, 1905 (F. 

 E. Watson) ; in author's collection. 



One old male, Blairstown, Warren County, New Jersey, June 2, 

 1920 (A. B. Klots) ; in the collection of A. B. Klots.
