Lts food is the làflafras, th e caterpillar folding a le a f together for an habitation,
and removing to a new one, as its fuffenance around is exhaufied, Thefe caterpillars
exhale a remarkable fcent,. whence th ey are fomethnes called Mellow-worms.
Haying changed in th e beginning o f October, th ey remained in th e chryfalis Rate
lall lo th o f March. One o f them in Virginia changed October 13th, and th e
fty did n o t come out till April Sth. This butterfly is frequent about blofloms in
th e fpring ; and as th e we ather grows h otter, reforts to w e t places in court-yards,

After much Rudy and confutation we have not been able to refer this infect tà any Lin-
nasan orFabrician fpecies. Whether it may be the Glaucus of Fabricius in his new work (that
of his Mantiffa is now named Laadacm), it finelycannot be the original G W « of Linnæus,
figured by GleijJjA 24. ƒ. i. and by Uramér, t, 139. ƒ. A.B. which iskearly difiinguiffied
*he'remarkable brown line on the Under fide of its hind wings, as well as by its general
colouring and marking. Mr. Jones, whole opinion is of the. firft authority, fuppofed our
right-hand figure, No. 2, to be Tnihis of Linnæus, which it certainly much refembles, and
the other to be a different fpecies. For this we mud rely on the accuracy o f Mr. Abbot. If
No. 2. be a variety oCTroilus, the caterpillar, fo different fromthat in our lafl plate, muff
belong only to No’. 1, of which No. 3. feems indubitably the undcr-fidc, and which we here
defcribe as new by the name of Ilioneus.
