NEW BRITISH SPECIES IN 1855. 43 



Head and face reddish-yellow; palpi whitish; antenna? 

 fuscous, basal joint whitish. Anterior wings dull bronzy 

 grey at the base, shading gradually into a dark purple fascia 

 in the middle; beyond the middle is a straight, shining, 

 rather slender, silvery fascia; the apical portion of the wing 

 is dark purplish-fuscous ; cilia fuscous. Posterior wings 

 grey, with grey cilia. 



Most nearly allied to N. Aurella, but readily distinguished 

 by the basal portion of the wing being dull bronzy-grey, 

 instead of rich golden-brown ; the fascia too is more per- 

 pendicularly placed, more slender and more silvery. 



I collected a few of the larvae of this species, at Lewis- 

 ham, in birch leaves, in September, 1854; it is thus noticed 

 in the Natural History of the Tineina, vol. i. p. 24 : — " A 

 larva, making long irregular galleries, which are entirely 

 filled up with dark green excrement." From these larvae I 

 bred a single specimen on the 26th of June. Its late ap- 

 pearance would imply that the species is only single-brooded. 



Nepticula Alnetella, n. sp. 



Alis anticis saturate aureo-brunneis, dorso basim versus 

 dilate aureo-brunneo, apice nigrescente, fascia paullo post 

 medium parum obliqua argentea splendidissima ; capillisfer- 

 rugineis. Exp. al. 2 — 2| lin. 



Head and face reddish-yellow ; palpi whitish ; antennae 

 fuscous, basal joint whitish. Anterior wings deep golden 

 brown, shading off to a pale golden brown on the inner 

 margin near the base; a little beyond the middle is a rather 

 oblique silvery fascia, extremely brilliant (more so than in 

 N. marginicolella) ; apical portion of the wing dark purple, 

 almost black ; cilia dark fuscous. Posterior wings grey, with 

 grey cilia. 



Not likely to be confounded with any other species, except 

 Aurella and Marginicolella ; from both it is distinguished
