times even to black, so that no markings are visible, the base and 

 apex, however, being mostly paler than the rest of the wing. 



Not rare on fences under elm trees at Camberwell in July. 



This species is exceedingly like G.fugacella, Z., and not easy 

 to distinguish from it. Herr Zeller, however, assures me it is 

 quite distinct, fugacella being rather larger, and having broader 

 anterior wings : it is not yet discovered in this country. 



Sp. 65. Desertella, Edleston (MSS.) 



Alae anticae angustse, luteo-fuscae vel luteae, punctis quatuor 

 nigris, apicibus punctis nigris circumdatis. Alae posticae 

 griseae, apicibus acuminatis. 



Expansion of wings, 6 lines. 



Head, palpi and thorax luteous; antennae annulated black and 

 white. Anterior wings narrow, linear, in colour varying from 

 light to dark luteous, and in some cases nearly fuscous, with four 

 black dots, of which one, faint, lies in the groove near its base ; 

 another, also in the groove, before the middle ; the third, near it, 

 but above and beyond ; and the fourth, in a line with the third, 

 still further removed ; the apex surrounded with black dots. 

 Posterior wings greyish, with the apices acute. Body light fus- 

 cous. Legs luteous. 



Very like G. terrella, but smaller, unvarying in size, and with- 

 out a trace of a fascia ; also the apex of the posterior wings is 

 more acute, and not so gradually produced. 



Found abundantly in the sand hills at New Brighton and near 

 Weymouth in June and July. Herr Zeller has sent me a speci- 

 men of his variety a of G. terrella, which agrees in most respects 

 with this species, except that it has a faint fascia, a character which 

 I have never seen in any one of the multitude of desertella I have 

 observed.

Expansion of wings, 6 lines. 



Anterior wings black, with a whitish fascia just beyond the 

 middle, curving slightly outwards, opposite to which, on the under 

 side, is a small yellowish costal spot. Posterior wings fuscous. 



Found in several places near London.
