margin of the wing, somewhat resembling the human shank and foot ; on 

 the outer margin is a broad fimbria of the same colour, cilia white. 



In some examples there is a rounded whitish patch on the central fascia of 

 the anterior wings towards the inner margin, and sometimes a quadrate one, 

 anterior to the ear-shaped mark; the strigse are frequently very boldly 

 marked ; and in one of my specimens the central fascia on the posterior wing 

 is irregularly carried on to the inner margin, while the base of the wing itself 

 is dusky. 



Caterpillar varied with dark and pale fuscous, with some yellowish spots and 

 interrupted longitudinal streaks, the cilia on the sides whitish : it feeds on 

 Salix ViteUinae : — the imago appears in the beginning of August. 



Not an uncommon species, occurring plentifully in places where 

 willows abound throughout the metropolitan district.

Head and thorax deep fuscous, minutely speckled with black, hairy and yellowish : 

 anterior wings of a deep yellowish-ash, clouded with fuscous, with dark trans- 

 verse rather indistinct undulated strigje, two of which in the middle of the 

 wing are considerably angulated, and between them is a yellowish white patch 

 in which are pretty correctly represented the letters J G, the latter very con- 

 spicuous, and between these and the inner margin is a pale rounded and some-

Head, thorax, and anterior wings bluish-ash, or griseous, slightly undulated, 

 with a broadish fuscescent striga towards the hinder margin, and a flavescent 

 patch on the disc : posterior reddish or dvdl crimson, with a regularly arcuated 

 black fascia in the middle, not reaching to the inner margin, and a fimbria of 

 the same hue ; cilia flavescent ; abdomen rosy above. 



The caterpillar feeds upon the oak:— the insect is a native of Sweden, Norway, 

 and other pans of the north of Europe. 



Ca. Pacta has doubtless been introduced into our Fauna through Wilkes's mis- 

 take in referring the common Nupta to the Pacta of Linne; a name sub- 

 sequently copied by Berkenhout, and afterwards by Turton and others.
