2.—_Alope_ was described by Fabricius, Ent. Syst., 1793, as fuscous
(_fusca_) with a yellow (_flava_) band; with two ocelli on fore wings;
on hind wing one ocellus above, six below. The band is very broad in the
female, usually narrower in the male, pale yellow in both sexes. The
ocelli resemble those of _Nephele_ and vary in same manner. Usually they
are round, but sometimes oval; are either small or large, often equal,
but sometimes the upper is larger, at others the lower. Now and then a
third pupilled ocellus appears, and individuals have been taken with
but one ocellus (the upper). It is not very unusual to find examples in
which a black point, or what may be considered as a rudimentary ocellus,
presents itself. On the upper side of hind wing is often a small but
complete ocellus near inner angle, but in many cases it is partly or
wholly wanting; and occasionally there are one or two black spots in
addition. The males in the majority of examples have six small ocelli on
the under side of the hind wings; the females rarely have six, and often
none at all. At the north, _Alope_ is blackish-brown, more brown in the
female; but to the southward brown prevails in both sexes; and it is of
a lighter shade, while the under side has a tint of yellow more or less
decided over whole surface, often mixed with gray. The band is of yellow,
or with a slight ochrey tint. This is a description of the extreme
southern type, and to distinguish I call it var. _Texana_. All examples
from Texas which I have seen have a complete anal ocellus, and six ocelli
beneath, of pretty large size—larger than in northern _Alope_—in distinct
ochrey rings; the pupils white points with a few blue scales about them
in the larger ocelli. Of 70 _Nephele_ ♂ examined, 50 have 6 ocelli, 11
have 5, 3 have 4, 3 have 3, 2 have 1, 1 has 0.
Of 55 _Nephele_ ♀, 6 have 6, 1 has 5, 4 have 4, 13 have 3, 7 have 2, 13
have 1, 11 have 0.
Of 24 _Alope_ ♂, 15 have 6 ocelli, 3 have 5, 4 have 1, 2 have 0.
Of 25 _Alope_ ♀, 12 have 6, 1 has 4, 4 have 2, 4 have 1, 4 have 0.
Therefore of _Nephele_ ♂, 71 per cent. have 6 ocelli, 4 per cent. have
under 3; 1.4 per cent. have 0.
Of _Nephele_ ♀, 11 per cent. have 6, 56 per cent. have under 3, 20 per
cent. have 0.
Of _Alope_ ♂, 62 per cent. have 6 ocelli, 25 per cent. under 3, 8 per
cent. 0.
Of _Alope_ ♀, 24 per cent. have 6, 48 per cent. have under 3, 16 per
cent. have 0.
