viaxiUoe short. Antennw rather long, slender, finely pubescent within in tlie 

 males, simple in the females : head small, with a tuft on the crown : ei/e$ 

 lateral, subglobose : thorax not crested : wings deflexed during repose ; 

 anterior somewhat lanceolate, rounded at the apex, and gcrrerally marked 

 with transverse irregular bands, rarely immaculate; posterior ovate-tri- 

 angular, entire : abdomen moderate, carinated on the back, and with a tuft 

 at the apex; stouter and obtuse hi the females: legs slender, short. 



In this genus the anterior wings are somewhat narrower in pro- 

 portion than in the other genera of this family, and are rounded at 

 the apex, the posterior margin being rather straight ; they are gene- 

 rally adorned with interrupted or waved darker fasciie upon a light 

 ground, though in some cases they are nearly immaculate ; there is, 

 however, a peculiarity of habit about the species, by which they may 

 be more easily recognized than described.

Anterior wings white, prettily, but distantly sprinkled with brownish-black, 

 with an irregular angulated black fascia near the base, widest on the costa, 

 and narrowing on the inner margin ; about the middle is a second very 

 oblique fascia, composed of three spots, which are occasionally remote, at 

 other times united by a narrow line, thus forming an irregular bar on the 

 costa: near the tip are three other black spots, opposite to the central one 

 of which, on the hinder margin, is a fourth, forming a second interrupted 

 oblique fascia ; cilia ashy, with darker clouds : posterior wings whitish-ash, 

 with some darker spots on the hinder margin ; cilia whitish-ash.

 — Differs in being rather larger and in having the fascia composed of dis- 

 tinct minute black spots. 



Scotland and the north of England are the only localities I am 

 aware of for this pretty species, which occurs in the beginning of 

 July. 



B. Anterior wings narrow, luteous-white, indistinctly fasciated, or imma- 



culate : — DoLOPUORA, H'vbner. 

 Sp. 2. longana. Alis anticis luteo-albis fusco maculatim fasciatis. (Exp.
