POANES HOBOMOK (Harris) 



Plate 54, Figures 13 to 18 



Occurrence. — Uncommon. In the Schonborn collection there are 

 2 males, 1 dated June 5, and 7 of the dark females (form poca- 

 hoQitas). Mr. Shoemaker has specimens taken in the District with- 

 out date, and in Arlington County, Va., on May 26, 1900. I have 

 two males and several dark females from Cabin John and Silver 

 Spring, Md. 



Season. — This species is single brooded. It first appears in the 

 last week in May, is most frequently seen during July and August, 

 and disappears before the middle of September. The earliest and 

 latest dates available are May 26 and September 10. 



Remarks. — In this butterfly the two sexes inhabit quite different 

 regions and meet only on the borders of their respective areas. The 

 males are found in damp glades in the woods and especially along the 

 banks of streams, while the females are seen only in open fields often 

 at a considerable distance from the woods. Such a separation of the 

 sexes is characteristic of various butterflies in tropical America, but 

 is unusual in this region. 



In New England I have found both sexes of this insect in the same 

 regions.

 Plate 54, Figures 7 to 12 



OcGicrrence. — Frequent, and sometimes rather common, the males 

 in damp open glades in the woods near streams and along the grassy 

 banks of streams flowing through woods, the females occurring in 

 open fields more or less near damp woods. Mr. Shoemaker has a 

 specimen from the District taken on May 22, 1900, and there are six 

 specimens from the District in the Schonborn collection. 



There are two specimens from Washington in the National Museum 

 collection, a male and a female taken by A. Koebele on June 4, 1882. 



Season. — This species is single brooded. It usually appears during 

 the last week in May, sometimes as early as the second week, is most 

 common during July and August, and disappears just before the last 

 week in September. The earliest dates are May 11 and 22, and the 

 latest September 19. 



Though usually this butterfly is first seen at about the first of the 

 last week in May, in 1930 it appeared in the second week in May 

 and was common by the end of the month. 



Notes. — This beautiful skipper is usually seen sunning itself on 

 leaves from 3 to 5 feet from the ground, or on tall grass blades. It
