being linear, not angulated ; the inner margin also is paler. From 

 G. marmorea it differs in being slightly less, of a greyer colour, 

 paler on the inner margin ; the first fascia well defined, not merged 

 in the ground colour ; the whitish fascia being also well defined, 

 and the apex of the wing darker.

Expansion of wings 5 lines. 



Head rufous ; palpi, second joint griseous above, black be- 

 neath, terminal joint black. Thorax rufous. Anterior wings 

 rufous, sometimes nearly black, with a darker, thick streak ex- 

 tending from the costa before the middle, and a blackish spot on 

 the disk beyond, adjoining which is a slender yellowish fascia ; 

 the inner margin is pale rufous or ochreous to beyond the middle, 

 extending upwards to the centre of the wing in the form of a 

 double arch. Posterior wings griseous. 



Found abundantly on the sand-hills at New Brighton, Cheshire, 

 at Chesil Bank near Weymouth, and Dawlish Warren. There is 

 not a tree of any kind near these places, and therefore I am in- 

 clined to think that, although it is taken on trunks of firs at Glogau 

 and Frankfort, it only goes there for shelter. Neither can I 

 concur in the opinion that maculiferella and junctella are only 

 varieties ; for among hundreds of specimens of marmorea, many 

 of them most extraordinary variations, I never saw one that could 

 be referred to either of those species ; and all three are found by 

 us in different localities and under different circumstances, as I 

 have indicated under each. 



Differs from G. junctella in being larger ; anterior wings having 

 the colour of the superior and inferior margins more distinct 

 and meeting abruptly in the centre, the hinder fascia narrower 

 and more obliquely placed ; apex paler. 



Differs from G. maculiferella in being larger, anterior wings 

 browner, wanting the pale base and the large angulated blotch ; 

 in the entire costa being dark, and in having a well-defined, 

 light inner margin. 



These last five species, possessing characters very much in 

 common, form a group not easily divisible, and difficult to iden-
