PAPILIONIDAE: PAPILIONINAE. 1851 



general behave in same way, at all stages resting on a lining of silk, 

 which they had spun on middle of the leaf, whereby the leaf is curled or 

 drawn together so as to afford a concealment." But in New England, the 

 caterpillar of troilus is completely concealed, the edges of the portion of 

 the leaf used for shelter being tightly closed. "This," he continues, "they 

 rarely leave, and then only when hungry, feeding on the end of the leaf 

 until it becomes too small for a hiding place, after which they betake them- 

 selves to another leaf. But these larvae do not cut into the side of the 

 leaf and fold down the cut portion as troilus [sometimes] does. This Dr. 

 Wittfeld states in reply to my enquiries." 



Dr. Wittfeld further says of the habits of the imago, as quoted by Ed- 

 wards : — "Palamedes roosts on the highesttreeit can find, oak or palmetto. 

 I have seen four to six near sundown fluttering about the tree, where they 

 finally settled and remained. Sometimes three or four so roost on one 

 large palmetto leaf." And he adds in notes sent me "with spread wings," 

 which appears very remarkable. 



The insect is attacked by Pteromalus vanessae (89 : 3) which Dr. Riley 

 reared in April from chrysalids sent by Mr. Barlow of Missouri.

Imago. Head and appendages as in polyxenes. Wings with the same colors as in 

 that species. Fore wings rich black brown with precisely similar markings in the 

 male and female, viz., a submarginal series of round yellow spots tending to become 

 sublunulate on the lower half of the wing, double in the medio-submedian interspace, 

 found in all the interspaces, at the centre at an interspace's distance from the border; 

 an extra-mesi.il series of roundish triangular, large, sublunulate spots, their common 

 exterior limit nearly straight, subparallel to the outer margin and removed from it by 

 about two and a half interspaces in the middle of the wing ; the inner extremity of 

 all of them is powdery, the outer limit clearly detined ; those in the medio-submedian 

 and submedio-marginal interspaces are nearly quadrangul.ir ; above this they decrease 

 regularly in size to the spot in the subcosto-median interspace, above which they in- 

 crease again in the same degree, the spot occupying the extreme base of the outermost 

 subcostal interspace interrupted by a large, long oval, blackish brown spot which occu- 

 pies all or nearly all its entire width in the basal three-fifths of the spot, usually breaking 

 it into two entirely distinct portions ; in addition there is a large round spot . generally 

 lar"er than any of the submarginal spots, surmounting the last divarication of the sub- 

 costal nervure, and a transverse bar of yellow marks the extremity of the cell. On the 

 hind wings the markings are again precisely identical in the two sexes; the same two
