Season. — This butterfly appears locally from the end of June to 

 the middle of July and flies until September. Mr. Townes writes 

 that where he lias collected it it is commonest in its prime in the first 

 half of July. On White Top and Balsam Mountains it does not 

 appear until the second week in July. There is only a single brood. 



Occurrence. — The butterfly is common wherever it occurs regu- 

 larly, frequenting especially roads through the woods, clearings, 

 and the bordei's of wooded areas. 



Food plant. — Gooseberry (Ellison A. Smyth, Jr.). 



Remarks. — Three other species of Polygonia occur in Virginia. 

 One of these, P. progne, is confined to the mountainous region in 

 the western part of the State, where it is very common in the 

 Transition Zone, at the higher altitudes overlapping the lower por- 

 tion of the range of P. faunus smythi. The two other species, 

 P. interrogationis and P. comma, occur at all points in the State, 

 though they are generally less numerous on the Coastal Plain than 

 elsewhere; P. interrogatio7iis is frequent or rather common almost 

 everywhere, but P. comma is less numerous and is nowhere found in 

 any great numbers. Neither P. interrogationis nor P. comma is at 

 any point so common as are P. faunus smythi and P. progne in tlie 

 regions where the two latter occur. 



On the lower borders of the range of P. faunus smythi all four 

 species are found, P. progne far outnumbering the others. At one 

 place on White Top Mountain where a small stream crosses the road 

 up the mountainside we took P. faunus smythi, P. progne, and 

 P. comma within a few minutes on the same square foot of moist 

 earth. 



Although in Polygonia faunus the individuals from Virginia 

 and southward represent a local race quite distinct from the typical 

 northern form, we fail to detect any corresponding differences be- 

 tween southern and northern specimens of P. progne, P. comma, or 

 P. interrogationis. Southern individuals of these three species are 

 frequently somewhat larger and darker than individuals from 

 farther north, but the differences are slight and inconstant and are 

 confined to relatively few specimens.
