HABITS OF AMERICAN PAPILIONES. 61 
as Drury’s Protesilaus, a Jamaica insect, of which I have a specimen, 
perfectly agreeing with Drury’s figure. 
The first species I will mention is Pap. Ajax, undoubtedly, I 
think, the P. Marcellus of Cramer. This is, Z believe, found chiefly 
in the lower country of the southern States, east of the Allegha- 
nies ; its range, I believe, is from Virginia to Florida inclusive. In 
Florida it was not very rare from April to June, but like most of 
the swallowtails was often imperfect, the tails being torn off. I 
rarely saw it alight on flowers, never that I recollect on the ground. 
Now and then it would alight on the flowers of Annona grandiflora, 
on which and An. (Porcelia) pygmeea, I have no doubt the larve 
feed there. Abbot gives it on An. (Uvaria) triloba, a shrub not 
growing in the part of Florida I collected in. Its flight low, rapid 
(not sailing with its wings expanded as P. Thoas and others). It 
flies in and around the low scattered brushwood, by the sides of clear- 
ings, old deserted cotton fields, and similar situations, often returning 
to the same spots; in fact so regular did the round seem to be 
taken, that I often have waited behind a bush for a few minutes for 
the return of an individual I had seen pass, and rarely failed by this 
means to capture it. It is ashy insect, and darts out of its course 
at the least motion. I think the remark in Boisduval of its 
alighting on fruit-trees must belong to some other species, probably 
the error has arisen from some confusion in Leconte or Abbot's 
notes. 
P. Marcellus. Boisd.—I first saw this lovely butterfly in the 
streets of Wheeling (Virginia), on the 10th of September, 1837. 
It was very numerous there. I afterwards took it in Portsmouth 
(Ohio), about 160 miles lower down the Ohio river. I think it did 
not occur to me in the perfect state at Cincinnati, where I found the 
larva on Uvaria triloba. Cincinnati is the westernmost point north 
of the Ohio that I observed it. Foster took it in the easternmost 
part of Ohio, and I observed it south of the Ohio, along the slopes 
of the Alleghanies, in Kentucky, and Tennessee, in July, 1838, in 
tolerable numbers. Its flight is rather more graceful than that of 
P. Ajax. It sometimes alights in the muddy places by the roadsides 
where little streamlets cross, especially during the heat of the day. 
This and P. Ajax, when perfect and fresh from the pupa, are of a 
lovely pale green, which, however, soon fades to the dirty white of 
Boisduval’s figures. My specimens are fast fading, but still retain 
a good deal of the green.
