PSYCHE.
THE CHRYSALIS OF FENISECA TARQUINIUS.
BY SAMUEL H. SCUDDER, CAMBRIDGE; MASS.
In Psyche for January, 1892 (Vol. on the plate (3) opposite this page the vi) Dr. W. J. Holland gave a greatly
result. The view, as will be seen, is
enlarged figure of the chrysalis of Spal- dorsal and taken obliquely from in gis s-signata of West Africa to show front and at one side, as this brings out the extraordinary likeness a slightly best the characteristic features, and it oblique aspect of the creature bore to
a human or rather a simian face.
This was the more curious because,
as pointed out by him, a similar like-
ness had before been remarked in the
chrysalis of our own Feniseca tarquin-
ius, by Mr. Edwards and Miss Morton ;
and because in both cases the larva is
aphidivorous - an exceedingly excep-
tional carnivorous habit for the cater-
pillars of butterflies. The original
paper by Mr. Edwards, including Miss
Morton's observations, will be found
in the Canadian Entomologist for Aug-
ust, 1886 (vol. xviii). The simian
resemblance has also been shown in
an Indian Spalgis in the Journ. ~orn:
bay Nat. Hist. Soc., Vol. 8, pi. A.
In the early part of last August Lt.
Wirt Robinson, U. S. A., sent me in
alcohol from Hot Springs, Va., a chry-
salis of Fcniseca which he had found
on the under side of a maple leaf and
suggested that it would furnish an
opportunity for a drawing which should
show "the perfect resemblance which
it bears to a face." I follow my
friend's suggestion and show herewith
is, moreover, nearly the same point of
view as that used by Dr. Holland for
Spalgis. The resemblance is not so
striking nor so grotesque as there, nor
is the expression so leering, but it can hardly be overlooked and is certainly
extremely curious. A dorsal view of
Feniseca also enlarged was given in the
Entomological News for September,
1896 (vol. vii), but seems to be less sat- isfactory than a partially lateral view. It may be added that Lt. Robinson
found the larva feeding upon aphid
colonies on the twigs of maple at Hot
Springs, the species being doubtless
Pemphigus aceris Monell. It has
heretofore been found principally in
the colonies of the alder plant-louse,
Schi'aonezwa tessellata, but also in
those of Pemphigus fra-xinz~olia and
P. imbricator of the ash and beach
respectively. The larva has also been.
fed in captivity on aphides from other
plants, and as it has been reported as
occurring on still other plants may
doubtless have a considerable range of
aphid diet and probably be found any-
where on colonized plant lice.
