band ; or in other cases traversed with simple waved darker striga? alone 

 on a pale ground; posterior frequently resembling the anterior, sometimes 

 obtusely angulated : abdomen rather short, stout, acuminated to the apex, 

 which has a rather conspicuous broad tuft in the males. 



The pretty insects that constitute this genus — which is palpably 

 a very artificial one — may be readily known by their plain light- 

 coloured wings, which are usually adorned with numerous dark 

 transverse strigse intermixed with pale fasciae : the palpi are short, 

 and the antennae simple. The first twelve and the last species 

 differ considerably in habit from the intermediate ones and from 

 each other : the genus must hereafter be subdivided.

Wings whitish, the anterior with several fusco-testaceous strigse, forming fasciae 

 by their confluence, the central one being most conspicuous and bilobed in 

 the middle of the posterior margin ; this is followed by a white fascia, which 

 is interrupted in the middle by the lobe of the fascia ; on the hinder margin 

 is an undulated white striga. 



Very abundant in the hedges and lanes in the fields between Pen- 

 tonville and Highgate, also at Hertford, towards the end of June.

Anterior wings somewhat of a tawny-brown, and obsoletely strigated with fuscous 

 waves ; beyond the middle is a conspicuous narrow sinuated white fascia, in 

 which is a fuscescent waved striga ; into this fascia, near the middle, the 

 brown base of the wing extends in a double lobe ; and between the fascia and 

 the hinder margin is a very obsolete striga, composed of white lunules, and at 

 the apex an obscure oblique fuscous spot : posterior wings pale fuscous, with 

 a somewhat crenated paler fascia a little behind the middle. 



Not very common : taken occasionally in Copenhagen-fields in 

 June, and in the vicinity of Hertford. " Epping." — Mr. Doiihle-
