BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
cylindrical, usually with very fine short hairs. They also 
lack the scent-organ of the Papilios. They live almost ex- 
clusively on plants belonging to the pulse family (Leguminosz) 
and the mustard family (Crucifere). The chrysalids may be 
distinguished at once by the presence of a single pointed pro- 
jection in front, and sometimes they are very much enlarged 
ventrally, so as to be almost triangular in shape. The eggs are 
much longer than broad, taller than those of any other group 
of butterflies; they are vertically ribbed, and almost invariably 
laid singly, though sometimes in open clusters.
