Macrolepidoptera of Staten Island 7 



that I took P. olcracca on Staten Island between 1856 and 1859." 

 At present the occasional specimen does not attract attention 

 among the similarly colored imported cabbage butterflies. 



Pieris rapae Linnaeus. i\Iarch to November inclusive. 



Catopsilia eubule Linnaeus. Usually appears in September 

 about the middle of the month, and in some years is quite com- 

 mon. Two specimens, one of which was captured, w^ere found 

 near the Billopp house, at Tottenville, October 4, 1903. 



Colias caesonia StoU. The dog's head butterfly was unknown 

 in the vicinity of New York City until the summer of 1896. In 

 June of that year Captain Robert D. Wainwright captured a 

 single specimen on the island at Eltingville. On July 11, in a 

 partly overgrown field at Kreischerville, near the Ultramarine 

 Avorks or " Blue factory," as it is locally called, I saw a number 

 of C. caesonia. A few hovered about the butterfly weeds 

 (Asclepias tubcrosa), but most of them were carried across the 

 open ground by the strong breeze then blow^ing. There was less 

 wind the next day, when the same field was visited, and the 

 butterflies seemed slightly more inclined to light on the Asclepias. 

 My plan consisted in sitting under a persimmon tree in the middle 

 of the field, and when a butterfly came into the clearing I tried 

 to catch it. In this way two specimens were captured in about 

 an equal number of hours, and a few others, which were mostly 

 in a great hurry, were seen. The field was again visited on July 

 25, but the butterflies had disappeared. During this same sum- 

 mer the species was taken for the first time in Canada, near 

 Toronto and in southern Manitoba. Since 1896 it has not been 

 recorded as far north as Staten Island. 



Colias eurytheme Boisduval. This butterfl\- was seen in a 

 field near Richmond on October 20, 1900. As I did not have a 

 net with me the insect escaped, but it was approached to within 

 less than a yard, so the identification is certain. 



Colias philodice Godart. April to November inclusive. A 

 single specimen flying on Todt Hill December 6, 1891. 



Terias nicippe Cramer. Appeared in June. 1880. and was 

 very common through the summer and fall. Two males were
