clouded with brown ; cilia ashy-brown : posterior wings with a conspicuous 

 dusky spot towards the base, and two flexuous transverse fuscous streaks, 

 between it and the hinder margin, the latter clouded with abhy-brown ; cilia 

 pale ashy-straw colour. 



Variable in the tint of the ground colour : in some specimens the wings are 

 deeply sufTused with ashy-brown, and partially clouded with a darker tint, 

 the strigae more distinct : one or other of the latter is sometimes obliterated. 



The caterpillar is of a pale green and slender ; it feeds on nettles : the imago 

 appears the beginning of June, and continues for some time, occurring 

 towards the end of the month. 



By far the most abundant species of this genus tliroughout the 

 metropolitan district, frequenting gardens, hedges (where nettles 

 abound), fields, Src, and not uncommon in other parts of the country.

Wings plain uniform ochraceous-yellow ; anterior with a faint incurved 

 brownish streak midway between the base and the middle, a lunate spot, of 

 the same tint, in the middle towards the costa, and a very flexuous striga 

 between it and the hinder margin, terminating nearly in the middle of the 

 inner margin; posterior wings with a brownish spot towards the base, and 

 an irregular streak in the middle, arising from the costa, opposite to (and 

 in continuation of, as it were) the posterior one of the anterior wings ; at 

 about one-third of its length it becomes suddenly angulated towards the 

 hinder margin, and upon reaching half way is then continued, in a zigzag 

 form, parallel thereto, for a short distance, and turns inwards with a similar 

 angle, and after a second bend, again at right angles with the last, terminates 

 on the inner edge : on the hinder margin is a very faint brownish line ; cilia 

 of all the wings immaculate ochry-yellow. 



Of this very conspicuous species I have seen only the specimen 

 which is contained in my collection ; it was taken in Devonshire.
