few may, however, breed in secluded parts of southern New Jersey. 

 Specimens have been secured in the vicinity of Philadelphia as late 

 as March 5 (Haddonfield, N. J., W. L. Abbott, M. D.), and as early 

 as August 25 (Olney, Pa., G. S. Morris). On the coast it seems to 

 be rarer than inland. 



At Lake Hopatcong, in northern New Jersey, this species is re-
