Head and face ferruginous. Antennae dark fuscous, in the £ 

 nearly as long as the anterior wings, in the 2 about half the length 

 of the anterior wings. Thorax golden brown. Abdomen, legs and 

 tarsi dark fuscous. Anterior wings of the $ golden brown or 

 greenish golden, with the costa at the base purple ; a little before 

 the middle of the wing is a transverse silvery spot which reaches 

 neither margin, and about the middle of the wing is a silvery fascia 

 placed rather obliquely, it being nearer the base on the costa than 

 on the inner margin ; beyond this is a small silvery spot near the 

 costa. Cilia golden brown. Anterior wings of the 2 (entirely 

 destitute of the silvery markings) golden-brown, with the costa at 

 the base purple. Posterior wings pale grey, with the apical half 

 tinted with purple. 



A common species ; I have several times found it in plenty, — 

 in a wood near Ambleside and in a lane near Coniston in June, 

 1846, and on a grassy bank near Carron in June, 1847, when I 

 took several pairs in copula ; last year I again took it in the same 

 place. The sexes are so different that they have long been con- 

 sidered as distinct species, although Scopoli appears to have been 

 aware of the several discrepancies. 



The 2 much resembles calthella, but independent of the wings 

 not being sulcate ; the base of the anterior wings is never purple 

 to the inner margin, but only a little way from the costa. 



The $ somewhat resembles subammanella and Tinea bistrigella, 

 but is distinguished from the former by its more golden anterior 

 wings, silvery spots and fascia, whereas in subammanella there are 

 two entire yellowish fasciae on the purple anterior wings. From 

 T. bistrigella it is distinguished by its ferruginous head (Stephens, it 

 is true, says "head black" — this, probably, arises from his descrip- 

 tion being made from a worn specimen,) and also by the differently 

 coloured anterior and posterior wings ; the latter in the Micropteryx 

 being subdiaphanous, and purplish at the apex ; in the Tinea they
