from ten to fifteen feet above the ground keeping on till it is out 
of sight in contrast to the usual type which in its habits is much 
like V . hunt era. 
In Feniseca tarquinius it would seem that certain individuals 
are specialized as migrants. These fly slowly in a straight line 
across the fields usually a foot or so above the grass tops for long 
distances; in fact I have never seen them rest. Typically this 
insect’s flight is most erratic suggesting a small and very active 
satyrid, with frequent rests. 
Basilar ehia archippus (Cramer).- — Both the boys reported in 
this species a pronounced and disagreeable odor which the 
younger compared with that of Ariosia plexippus females. It is 
not a little curious that this butterfly should both look and smell 
like this larger form. But the flight of the two is different and 
one can easily tell them on the wing at any distance. 
Anosia' plexippus (Linne). — The females have a rather 
strong and disagreeable odor resembling that of cockroaches or 
of carrots. The males have the same odor, but in them it is very 
faint and is overlaid with a faint very sweet odor like that of 
milkweed or red clover flowers. 
Eurymus philodice (Godart). — The males have a distinct 
and uniformly strong odor resembling that of sweet grass or 
sweet hay. The females seem to be odorless. 
Eurema euterpe (Menetries).— The males, in spite of their 
diminutive size, have a pronounced fragrance similar to that of 
the males of the preceding species but sweeter and more flowery. 
Papilio polyxenes Linne. — The males have a faint sweet 
odor resembling that of carrot flowers which is very pleasant. 
Apparently an identical odor is found in the males of the Euro- 
pean P. machaon. 
Two males examined in Washington had a strong sweet 
flowery odor of the same type. 
Papilio glaucus Linne. — The males all have a sweet flowery 
odor varying from faint to fairly strong which resembles that of 
the males of P. troilus though it is never so pronounced. The 
females have a disagreeable odor pungent in quality resembling 
rubber cement or creosote which is very strong in some and ap-
