Odors of some New England Butterflies 
5 
parently stronger in the females taken about Washington than 
in those taken in New England. The same odor can sometimes 
be detected in the males, though very faintly. 
Papilio troilus Linne. — The males have a distinct and rather 
strong sweetish odor difficult to describe but exactly resembling 
that of Nabisco or Huntley and Palmer’s honey biscuits. 
Laertias philenor (Linne). — From observations made in 
Washington it was found that the males have a sweet flowery 
odor similar to that of the males of Papilio polyxenes though not 
so strong. The females have a strong pungent and disagree- 
able odor. 
Mr. W. H. Edwards reported a disagreeable odor in this 
species but did not give the sex of the individual examined. Mr. 
Scudder very carefully investigated a specimen fresh from the 
chrysalis and f ound no odor. Mr. Edward’s example undoubtedly 
was a female. Mr. Scudder’s, which was a male, was probably 
too fresh for the odor to have become detectable.
