35^ PHYSICAL GEOGRAPHY. 



of the Connecticut river valley, but, owing to its local habits, it is ordi- 

 narily esteemed rare. It occurs only in moist, or moist and shady, mead- 

 ows of small extent. When young, it feeds on Chelone glabra ; after 

 hibernating, on Lonicera ciliata. 



33. Libythca Bachmanii Kirtl. Two specimens of this butterfly have 

 been taken at Littleton by Dr. F. F. Hodgman. With a single excep- 

 tion, this is the only known instance of its occurrence in New England. 



RURALES. 



34. Thecla Liparops LeC. This butterfly appears to be found through- 

 out New England, although everywhere considered a rare species. In 

 New Hampshire it has only been reported from Mt. Moriah, Thornton 

 (Faxon), and Milford (Whitney). 



35. TJiecla Edzvardsii Saund. Has been taken only in the extreme 

 southern parts of the state, Milford (Whitney) and Nashua (Harris). 



36. TJiecla Calanus Doubl. This butterfly seems to occur throughout 

 New England. In New Hampshire, it is very common at Walpole 

 (Smith), but is probably absent from the northern and perhaps the cen- 

 tral parts of the state, although it occurs at Norway, Me. 



37. TJiecla acadica Edw. This butterfly is rather widely distributed 

 in New England. In New Hampshire it has been taken only at Milford, 

 "very rare" (Whitney), and at Nashua (Harris). 



38. Callipareus Mclinus Scudd. A widely spread species that will 

 probably be found in every part of the United States. In New England 

 it is more abundant in the south than in the north, although it has been 

 taken as far north as Norway, Me., and Plymouth, N. H. Other locali- 

 ties in New Hampshire are Dublin (Faxon), Suncook (Thaxter), and 

 Milford (Whitney). 



39. Incisalia Augustus Min. The distribution of this insect seems to 

 be somewhat peculiar. Apparently reaching its maximum of development 

 in New England, it occurs also in the Canadian fauna, even as far as the 

 Cumberland house on the Saskatchawan, nearly in the centre of the con- 

 tinent, and has been described from California as a distinct species. 

 Yet notwithstanding its occurrence in California, it has not otherwise 

 been reported in the United States west of Albany. In New England 

 it is widely distributed, and will probably be found in abundance all over
