76 THE WHITE MOUNTAINS 



have survived the winter. The American Tor- 

 toise-shell (Agiais milberti) is also common in the 

 lower country, feeding in swarms upon the net- 

 tles ; and this concludes the series of Nymphalini 

 which need be mentioned. 



The Mountain Silver-spot (Argynnis atlantis) 

 occurs here in the utmost profusion, as nowhere 

 else in New England. One may easily take hun- 

 dreds in a single day, the sandalwood-scented males 

 largely predominating. The Silver-bordered Fri- 

 tillary (Brenthis myrina) and the Meadow Fritil- 

 lary (B. bellona) are abundant in the restricted 

 meadow-lands, and in about equal numbers, though 

 B. myrina is far more common in central New Eng- 

 land. But the region is one of the best for most 

 of our Melitaeini. The Tawny Crescent (Phyci- 

 odes batesii) occurs here early in June, and this is 

 its only known New England locality. The Pearl 

 Crescent (P. tharos) swarms (as it also does else- 

 where), and here is the best place to search for 

 those very local species, Harris's butterfly (Cineli- 

 dia harrisii) and the Baltimore (Euphydryas phae- 

 ton). They can best be obtained in the larval 

 state, for they may always be taken in large num- 

 bers very early in the spring in such conveniently 

 accessible spots as the immediate borders of the
