Lord Walsinghani on 
1840 (Syn. Gen. Br. Ins. 107), as nisella, CI. 
{=hdeherana, F., Westw.). Those authors who have 
subsequently followed Wilkinson [Br. Tortr., 127-8 
(1859)] in restricting the genus to species not possessing 
the costal fold, have succeeded in eliminating from it all 
the species originally included by Stephens, whether 
typical or otherwise. For the form which I have here 
to describe Zeiraphera is the oldest name and its type 
corticana, Hb., agrees with it in structure, but those 
who desire to follow Mr. Meyrick in including wceberiana, 
kSchiff., in the genus to which this species belongs would 
be justified in using the name Enarmonia, Hb., of which 
ivoeberiana is the type. 
Zeiraphera medioplagata, sp. n. (PI. XII., fig. 18.) 
Antennce (broken). Palpi greyish white, apical joint touched with 
fuscous. Head and Thorax greyish. Forewings whitish, with some 
silvery waved lines around the darker margins ; these consist of a 
dark reddish fuscous blotch, touching the costal margin beyond 
the middle and extending obliquely downwards to the outer and 
lower margins of the cell, where it is considerably dilated, and is 
nearly joined by a broad ferruginous streak from the apex, a 
branch of which also narrowly follows the apical margin ; a grey 
shade extends from the base along the costal portion of the wing, 
reaching to, and slightly blending with the median blotch ; a few 
small greyish spots along the costa before the apex and a faint 
ochreous tinge over the pale ground-colour on the apical portion 
of the wing ; cilia whitish, with a strong fuscous dividing line 
which extends round the apex but does not reach the anal angle. 
Exp. al^ 14-5 mm. Hinduoings pale greyish, with paler cilia, in 
which is a grey dividing shade. Abdomen pale greyish.
