NEW BRITISH SPECIES IN 1856. 109 



Elachista t2Ei\iatella, Zeller, n. sp. 

 Alls anticis saturate fusco-nigris, postice dilutioribus et 

 flavido-irroratis, fascia media recta latiuscula lutea ; 

 ciliis saturate griseis; capite saturate grisescente. 



Exp. al. A\ lin. 



Head, face and palpi dark greyish-brown. Antennas 

 blackish, anterior wings dark brownish black at the base, the 

 apical portion paler and irrorated with yellowish scales; 

 nearly in the middle is a straight rather broad yellow fascia, 

 sharply depressed on its edge, less so towards the apex; it 

 expands a little towards the inner margin. Cilia dark grey, 

 intersected by two darker lines. Posterior wings pale grey, 

 with darker cilia. 



The uniform dark colour of the cilia of the anterior wings, 

 the uniform colour and breadth of the fascia, and the yel- 

 lowish scales irrorated over the apical portion of the anterior 

 wings, are characters by which this species may be at once dis- 

 tinguished from the other known one-banded species of the 

 genus. 



The larva which Mr. Scott found at Stockton-on-Tees 

 feeds in the autumn, in November, in a rather coarse grass 

 (probably Arrhenatherum avenaceum), in which it forms 

 brownish mines, somewhat like those of E. Megerlella. 

 The larva hybernates full fed, changing to a pupa in the spring. 

 The perfect insect appears in April. This larva was also 

 found by Herr Schmid at Frankfort on the Maine.
