rection. Posterior wings shining grey, with a fuscous tinge at the

A common species in the north of England. Constant in size, 

 but variable in its colours. In the Stephensian collection, in the 

 British Museum, is a dark suffused variety, which the late J. F. 

 Stephens elevated to the rank of a species, and described it in 

 the ' Mus. Cat/ part x. Lepidoptera (continued), p. 100, under 

 the name of P. alticolana, but it is evidently nothing more than 

 a variety. 



The imago appears in July and August on moors and heathy 

 places, among Calluna vulgaris, in Yorkshire, Lancashire, and 

 north of England ; also around Edinburgh. 



Genus XL HEUSIMENE, Hub. ? teste STEPHENS. 



Palpi as long as the head, drooping, remote. Basal joint pyriform, 

 widest at its apex ; apical joint obovate, not so long as the basal ; 

 middle stout, obovate, three times the length of the apical. Maxillae 

 as long as the palpi. Thorax robust, globose. Anterior wings : 

 length equals three times the breadth. Costa very nearly straight ; 

 apex acute ; apical margin oblique, rounded; dorsal margin straight; 

 costal vein attains the margin before the middle ; the subcostal 

 nervures not equidistant. The discoidal cell lies in the upper half 

 of the wing, and extends two-thirds its length. Posterior wings 

 ample ; apex obtuse ; apical and dorsal margins entire ; basal angle 

 slightly produced. Abdomen stout in both sexes, with a small tuft 

 at the apex in the <$ . 



There is only one British species in this genus, which is re- 

 markable for the length and dull, dark, sombre colouring of its 

 anterior wings ; and also by the broad dark border to the poste- 

 rior ones, which are otherwise white. It is peculiar in its habits, 

 flies but seldom, and appears in the early spring.
