hinder margin ; yellowish brown curved streaks run from this fascia towards the costa 

 and hinder margin, and especially towards the apex. On the costa, among the dot-like 

 streaks, is manifest one like a spot beyond the middle, after which follows a broader 

 whitish gap. Cilia are pale yellowish gray, at the apex and end brown. 



" Under-side shining gray-brownish, with paler base of the cilia at the apex of the 

 wing. 



" Posterior wings formed as in cornella, only somewhat narrower, shining gray, 

 with pale cilia. 



" The brown scales are not attached firmly ; in wet weather and in flying many are 

 lost, and the markings then only partly remain, whilst judging from the cilia, the 

 specimens are still unwasted. 



" This species is very widely distributed in the Riesen and Erz mountains, and 

 is sometimes very abundant. Madame Lienig also discovered this species in Livonia. 

 It lives, as it appears, only in mountains and high latitudes : its food (Sorbus aucu- 

 paria) is not rare in the woods near Glogau, but still I have not been able to find the 

 moth on it. According to F-v-R.'s conjecture, which I cannot at present share, it feeds 

 also on species of Prunus. The period of flight begins in the middle of June." 



I beg to call the attention of the collectors of the North of England and Scotland 

 to this species : let those who have opportunities search for it on its food on the moun- 

 tain sides ; and should they meet with it, let them bear in mind that not a single 

 British cabinet possesses the insect, and consequently the demand for it must be very 

 great.

Expansion of the wings 6 lines. Head whitish. Face whitish. Palpi whitish. 

 Antennee whitish, annulated with black. Thorax whitish, with a slight bronze-co- 

 loured gloss. Abdomen fuscous. Legs silky whitish. Tarsi silky whitish. Anterior 

 wings whitish with a bronze-coloured gloss, with numerous short, dark, transverse 

 streaks ; from the middle of the base proceeds a darker bronze-coloured streak, which 

 extends about a third along the wing, and meets a fascia, or rather semi-fascia, of a 

 similar colour, which arises on the inner margin, and is carried rather obliquely to- 

 wards the apex half across the wing ; a little beyond this is another imperfect bronze 

 fascia arising on the inner margin and reaching nearly to the costa ; this is likewise 

 placed obliquely and terminates almost in a point ; at the anal angle is a bronze-co- 

 loured spot: cilia whitish, at the apex pale tawny. Posterior wings purplish gray; 

 cilia slightly brownish. 



This species is readily distinguished from Gcedartella by the first fascia being con- 

 nected with the base, by the second fascia not being forked, and by neither of these 

 two fasciae reaching more than half across the wing, whence the Haworthian name of
