184.0 (Syn. Gen. Br. Ins. 107), as nisella, Cl. 

 (=b(jeberana, 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 Zeiraph'era 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, 

 Schiff., in the genus to which this species belongs would 

 be justified in using the name Enarmonia, Hb., of which 

 woeberiana is the type. 



Zeiraphera medioplagata, sp. n. (PI. XII., fig. 18.) 

 Antennae (broken). Palpi greyish white, apical joint touched with 

 fnscous. 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. Hindwings pale greyish, with paler cilia, in 

 which is a grey dividing shade. Abdomen pale greyish.
