48. Ckrysopkanus epixanthe Westw. In New England this butterfly 

 has only been found east of the Connecticut valley. In New Hampshire 

 it has been taken at Milford, very plentiful in a few localities (Whitney), 

 Suncook, not common (Thaxter), and Hampton, abundant (Scudder). 



49. LyccBua avicricana Harr. It is found throughout New England, 

 almost as abundantly in the White Mountain district as elsewhere, and is 

 one of our commonest species. 



50. Fcniseca Tarquinuts Grote. The latitudinal distribution of this 

 butterfly is greater than that of any other of the American coppers, since 

 it is found from beyond the limits of the Alleghanian fauna on the north 

 to the shores of the Gulf of Me.xico. In New Hampshire it has been 

 taken at Berlin Falls, Thornton, "very abundant below the cascade on 

 Mill brook" (Fa.xon), Waterville, Manchester, and Milford.

51. Colias Philodicc God. In New England this butterfly is every- 

 where the commonest species, except in certain years, when it seems to 

 be affected by some unfavorable circumstances. It is found alike in the 

 White Mountain region and on the shores of the Sound, but is more 

 abundant in the southern than in the northern districts. 



52. Eurcvia Lisa Kirb. This butterfly is a member of the Carolinian 

 fauna, where it is very abundant. A single specimen has been taken by 

 Mr. Thaxter at the Isles of Shoals. 



53. Ganoris rapce Dalm. This butterfly is our most recent and least 

 desirable importation from the old world, and before many years it will 

 doubtless spread over the whole northern hemisphere. It was introduced 

 at Quebec, and has rapidly spread southward and westward. The first 

 specimens taken near New Hampshire were captured by Mr. Merrill, at 

 Waterbury, Vt., in August, 1867; yet it was only in May of the same 

 year that they appeared at Montreal. In August, 1868, they were not 

 uncommon at Island Pond, on the Grand Trunk Railway, and the suc- 

 ceeding year were taken in July by Mr. Sanborn, at Littleton, and by Mr. 

 Whorf, at Shelburne, and, in August, as far south as Campton, by the 

 latter gentleman. It was not until September of the same year that they 

 were discovered at Norway, Me., a few miles from Shelburne; and yet 

 they were taken at Waterville, in the same state, in May of that year,
