BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
which occurs on the alder. It is three-brooded, the first brood 
appearing from the latter part of May to the middle of June; the 
second early in July, continuing to fly until the early part of August; 
the third brood appears from the middle of August to the end of 
September. 
Family HESPERIDA. 
The members of this family are known as Hesperids or Skip- 
pers, the latter name having been applied on account of the 
peculiar flight of the species. The flight is very rapid, varied 
and interrupted, terminating suddenly after a short career and 
suddenly resumed. It is hurried and intermittent, never steady 
or sailing like that of the other groups. The butterflies almost 
invariably delight in the hottest sunshine, and generally fre- 
quent open meadows. They may be known readily by their 
antennz, which are abruptly hooked at the tip. The caterpillars 
have between the head and first segment a distinct neck which 
gives them a very characteristic appearance.

‘It is very difficult to give a satisfactory synopsis of the genus Pamphila, 
as the sexes of each species differ in markings on the upper side, especially on the 
fore wings. The males of some species are provided with a stigma, which is 
more or less distinct or wanting entirely; while in the females it is always absent. 
The markings and coloration of the under side of the hind wings, however, are 
constant in both sexes, and by means of this they may be readily united, or the 
species separated. The stigma is a velvety mark on the fore wings.
