and with a dusky or whitish undulated striga, the anterior one placed before 

 the middle, and edged exteriorly with black ; the posterior one behind the 

 middle, and bordered anteriorly with the same colour; behind the last is 

 generally a pale waved striga, and an obscure one on the hinder margin, wliich 

 has a slender dusky line; cilia slightly rosy : posterior wings whitish, with a 

 fascia behind the middle, and the hinder margin cinereous; cilia rosy or 

 whitish. I 



In some examples, the second transverse fascia is completely obliterated : and 

 others have the rudiments of a third striga at the base of the anterior wings. 



Caterpillar pale, with a fuscous dorsal line, and black head : it feeds on the oak : 

 — the imago appears towards the end of August. 



A rare species ; but found in several parts of the metropolitan 

 district: I have captured specimens at Darenth-wood, and have 

 seen others which were taken in the New Forest. " Epping." —

Head and thorax cinereous, the latter with a transverse striga in front; anterior 

 wings also cinereous, with a geminated striga at the base, then a fascia com- 

 posed of numerous undated fuscous strigoe, and behind the middle a second 

 fascia composed of five considerably angulated striga, the two outer ones being 

 black, the central one fuscous, and the other cinereous ; between the fascia are 

 two griseous spots in place of the stigmata, the anterior one round and ge- 

 nerally pupilled ; the posterior with two black or fuscous spots, and forming 

 a character resembling the letter R ; near the hinder margin is a slightly 

 waved palish striga, arising from an obhque dusky streak at the apex of the 

 wing, and producing, externally, some faint black streaks on the nervures ; on 

 the hinder margin is a faint interrupted dusky liiie : posterior wings fuscous, 

 with the margin darker, and the cilia cinereous. 



Caterpillar gi-een, with the head bromi, with the anterior margin black : — it feeds 

 on the poplar, and appears towards the end of June. 



Rare : taken in several places throughout the metropolitan 

 district : I have obtained specimens from Epping Forest, captured 

 near Chigwell Row, and have once taken the insect at Darenth. 

 I believe specimens have been taken in Devonshire.
