Butterflies, Fossil
by a curving granulated streak; it arises from the final curve of the
lowermost inferior subcostal nervule opposite and directly below its
origin; it passes thence in a slightly curved line, opening outward,
to the very base of the upper branch of the median nervure. The median
nervure runs in a straight line as far as its first divarication, which
is a little beyond the middle of the cell; thence it is bent parallel to
the subcostal nervure and exactly at the lower tip of the cell forks, the
branches parting but gradually from each other, the upper gently curved,
the lower nearly straight. The submedian nervure is parallel to the
lowest median nervule, as in Neorina, etc. None of the veins are swollen
at the base. The cell is three and a half times longer than broad.
In the hind wing the neuration is almost precisely that of _Neorina
Lowii_ (Pl. II, fig. 8). The costal and subcostal veins are confluent for
a short distance, when the costal parts from its neighbor at nearly right
angles and immediately thereafter sends up the basal shoot, which, after
passing in a straight line half way toward the basal angle of the costal
margin, curves slightly outward and fades away; the costal nervure, on
approaching the border, curves outward and meets the border near the
middle of its outer two-thirds; the subcostal breaks into three branches,
exactly as in Zophoessa. The median nervure and its middle branch form a
continuous, almost exactly straight line, from which the lowermost branch
parts opposite the union of the vein closing the cell with the lowest
subcostal nervule; and the uppermost at exactly the tip of the cell, or
as far beyond the origin of the lowest nervule as the upper limit of the
vein closing the cell is from the base of the upper subcostal nervule;
the vein closing the cell is a very weak one and originates on the lowest
subcostal nervule, as far from the second divarication of the subcostal
nervure as that is from the first, and passes in a gentle curve, opening
outward, to the second divarication of the median nervure. The submedian
and internal nervures are united for a short distance beyond the base of
the cell; the submedian passes with a gentle regular curve to the outer
border, at the lower outer angle; the internal parts from this with an
opposing curve and terminates somewhere below the middle of the inner
flap of the wing, probably approaching again the submedian nervure near
its extremity. None of the veins are swollen at the base. The cell is two
and three-quarters times longer than broad.
