THE INSECTS OF NEW JERSEY. 419 



COLIAS Fab. 



C. caesonia Stoll. The "dog's head butterfly." Taken on Staten Island 

 in June and July, 1896, and not since recorded. It is common further 

 south and west, and the larvae feed on clover and "Amorpha." 



C. euytheme Bdv. Mt. Holly (Aaron) ; Camden (Carney) ; Long Island 

 (Bt) ; Staten Island X, 20, 1900 (Ds). Very occasional and hardly a 

 regular inhabitant of the State. It is common in the Central States, 

 and the larvae feed on clover and allied plants. 



C. philodice Gdt. The common sulphur yellow butterfly, which occurs 

 throughout the State from early spring to late fall. The larva feeds 

 on leguminous plants, preferably clover, and while quite abundant, has 

 never yet become injurious. 



TERIAS Swains. 



T. nicippe Cram. Local throughout the State, rarely common, in May 

 and June and again in September and October. Specific records are 

 Orange Mt. Dist. (div); Waverly (Br) ; Elizabeth IX, 14 (Gr) ; Staten 

 Island VI (Ds) ; Mt. Holly, Westville, Atlantic City (Aaron) ; Cam- 

 den (Carney); 5-mile beach (Haim). The larva feeds on clover and 

 "Cassia." 



T. lisa Bdv. Lee. Throughout the Stat.e; but rather local and rarely 

 common north of the red shale. It is the most common butterfly at 

 Anglesea and along the shore in Cape May County in September, 

 occurring generally where its food plant, "Cassia," is plentiful. The 

 early butterflies in June, the later broods in August and September. 

 Belated examples have been taken in October, and there is no time 

 during the summer when it is not likely to be met with along shore. 



Family PAPILJONID^. 



These are the swallow-tail butterflies; all of them of large size, con- 

 spicuously marked, the hi-nd wings with a tail-like extension, which gives 

 them their common name. The legs are all complete, fitted for walking, 

 and the antennas are situated close together on the vertex. The cater- 

 pillars are unique in the possession of a protrusible fleshy process be- 

 tween the thoracic segments which, when extended, gives off an intense- 

 ly disagreeable odor. These processes are called "osmateria," and are 

 supposed to be defensive in character. The chrysalids are girthed at the 

 middle as well as fastened at the tail. 



PAPILIO Linn. 



P. ajax Linn. Local throughout the State, but usually only single ex- 

 amples at long intervals. The larva feeds on paw-paw, and wner- 

 ever this food plant does not occur the butterfly is a visitor merely. 

 Specific records are from Newfoundland VII (Ds) ; Hemlock Falls 

 VII, 1 (Br) ; Newark district (div) ; Staten Island VI, VII, VIII (Ds) ; 

 Anglesea (W).
