BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
miles of New York City and is intended to be used not only in 
connection with the Local Collection on exhibition in the Mu- 
seum, but also as a concise handbook for the purpose of identi- 
fying the species in the field. The butterflies found in the 
vicinity of this city are representative of four families, the 
Papilionide, the Nymphalide, the Lycazenide and the Hesperide, 
and will be described in that order. The figures used in illus- 
trating the species are all natural size, and most of them show 
the under as well as the upper side of the wings. Some of the 
figures illustrate also the wings of the female. The collection 
has been installed in the flat cases on the railing of the gallery 
in the Central hall of the third floor. 
Family PAPILIONID. 
The butterflies of this family found in the vicinity of New 
York are divided into two subfamilies: viz., Papilioninze and 
Pierinz. 
Subfamily PAapiLioNIN&. 
These are large butterflies, commonly known as Swallowtails, 
because of the tail-like appendages on the hind wings. In the 
tropics some species occur without these tails. The antenne are 
slender, the knob at the tip either straight or curved. The body 
is provided with six feet fitted for walking. The caterpillars are 
usually smooth or are provided with fleshy protuberances, and in 
the upper part of the first segment is a forked scent-organ which 
may be thrust out or drawn in at will. This organ gives off a 
disagreeable odor when extended, which serves as a protection 
to the caterpillar. The chrysalids are attached by the tail to a 
button of silk, and the body is suspended obliquely in a loop of 
silk that passes around it a little in front of the middle. The 
species of Papilio may be separated readily by the following 
synoptic table:
