that N. IBrizo during several years of thorough collecting had not 

 occurred at Center where N. Icelus was found so abundantly, the two 

 being associated in about equal numbers in New England, and elsewhere. 

 In 1870, an individual, believed to be Brizo, was inclosed in the net, 

 but escaped therefrom before it could be positively identified. The 

 following spring the species was not at all rare, and several pairs were 

 taken in coitu. In 1869, a single $> Hesperia Logan was secured at 

 Center, followed the ensuing season by several of each sex. Previous 

 to the present year (1871), Messrs. Tepper and Graef of Brooklyn had 

 obtained but one specimen of the rare H. Massasoit, while this season 

 they report it as not uncommon on Long Island.
