4 o8 REPORT OF NEW JERSEY STATE MUSEUM. 



No important change in general arrangement has been made in this 

 edition, and such changes as have been necessary are connected with the 

 previous work in the usual way. 



Super-family PAPILIONOIDEA. 



Includes the day-fliers or butterflies, characterized by having the an- 

 tennae enlarged into a club at tip, whence they have also been called 

 "Rhopalocera" or club-horned. They are usually of moderate or large 

 size, brightly colored and marked, and the wings, when at rest, are held 

 upright or vertical, the faces opposing each other, except in the skippers 

 or "Hesperidse," where the fore-wings are held vertically and the hind 

 wings are held horizontally. 



Dr. Henry Skinner, of Philadelphia, has been good enough to look over 

 the manuscript in this super-family and to verify such determinations as 

 seemed questionable. He has also added a number of records and notes 

 from his own experience. 



Family NYMPHALID^. 



These are the four-footed butterflies, in which the anterior feet are so 

 much aborted as to be useless for any purpose. The pupas are suspended 

 by the tail alone and are frequently ornamented by metallic gold and 

 silver spots. 



DANAIS Latr. 



D. plexippus Linn. Occurs throughout the State, May to November; 

 sparingly before midsummer, commonly until late September. The 

 larva feeds on milkweeds, and there are three broods. The chrysalis 

 is bright green with golden spots, and forms a conspicuous object. 

 This butterfly migrates in late fall and winters as an adult in the 

 Southwest. In May, scattering females return and provide for the 

 first brood of larvae, the butterflies from which remain here, lay eggs 

 and provide for the second brood of larvae. These develop in the 

 same way, the adults also remain at home and provide for the third 

 and largest brood of the season. The adults that hatch from this 

 brood of larvae have the migrating instinct developed, make no at- 

 tempt to reproduce their kind and leave in great swarms in late 

 September and early October for their winter home. They do not 

 reproduce there, and only the females return to their place of birth 

 in the spring following. 



AGRAULIS Bd. Lee. 



A. vanillas Linn. Cape May; 7-mile beach; Camden County; an occa- 

 sional visitor only, and may not breed in the State at all; the larva 

 feeds on "Passiflora."
