among the butterflies of Compton, Lower Canada, which is rather strange, 

 since it is found in the valleys of the White Mountains. 



URBICOLjE. 



59. Epargyrcus Tityrus Scudd. This is a tolerably common, some- 

 times abundant species in the three southern New England states, occur- 

 ring even in the elevated portions. North of this it becomes rare, having 

 been taken in New Hampshire only at Milford, "plenty" (Whitney), Dover 

 (Faxon), Walpole (Smith), and Plymouth (Scudder). 



60. Achalarus Lycidas Scudd. This is a rare insect in New England. 

 It has occasionally occurred in abundance in New Haven and vicinity, 

 and a few specimens are reported at rare intervals in various parts of 

 Massachusetts. Mr. Whitney has taken three or four specimens at Mil- 

 ford, the northernmost known locality for this insect. 



61. Thorybes Py lades Scudd. It is found in abundance in every part 

 of New England. 



62. Erynnis Persius Scudd. In New England it is everywhere com- 

 mon, from the valleys of the White Mountains and Norway, Me., to Cape 

 Cod, Norwich, and New Haven. 



63. Erynnis Lucilius Scudd. This insect has not been recorded from 

 New Hampshire ; but I have found empty nests of the larva among the 

 leaves of Aquilegia in Plymouth, which must have been made by this 

 species. 



64. Erynnis Icelus Scudd. It is widely spread over New England, 

 having been taken at nearly every place where there are resident col- 

 lectors. In the north it has been found in the wilds of Maine, at Norway 

 in the same state, in the valleys, and even in the sub-alpine zone of the 

 White Mountains, at Plymouth, and farther south at Milford. 



65. Erynnis Brizo Scudd. This, too, is widely spread in New England, 

 but has not yet been found in the White Mountain valleys, although it has 

 been taken at Waterville, Me., and Thornton, N. H. It has also been 

 reported from Dublin and Milford, in the southern part of New Hamp- 

 shire. 



66. Erynnis yuvenalis Scudd. This butterfly is confined in New 

 England to the three southern states, having been taken north of them 

 in but a single locality (Milford, N. H.), where it is reported rare.
