NEW BRITISH SPECIES IN 1858. 155 



by the whiteness of the head and the obliqueness of the 

 fascia. 



It occurs at Headley Lane, near Mickleham, in June and 

 July (see Trans. Ent. Soc. vol. iv. N. S. (Part 8), p. 303). 



Elachista perplexella, Stainton. 



This species had hitherto been confounded with Subni- 

 grella, from which it differs by the anterior wings being 

 blacker, ajid the spots more nearly opposite. 



The larva feeds in the leaves of Aira ccespitosa, and it has 

 occurred at Beckenham, Scarborough and near Edinburgh 

 (see Trans. Ent. Soc. vol. iv. N. S. (Part 8), p. 308). 



Elachista Cingillella, Fischer. 



Among the species which have only a single pale fascia 

 on the anterior wings and have the head dark, .this is espe- 

 cially distinguished by the slenderness and whiteness of the 

 fascia. 



Mr. Allis has a specimen taken in the North of England 

 some years ago (see Trans. Ent. Soc. vol. iv. N. S. (Part 8), 

 p. 312). 



Elachista Caricis, n. sp. 



Closely allied to E. Rhynchosporella, but darker; the 

 hinder margin of the anterior wings more truncate, and the 

 sub-apical costal spot placed more perpendicularly. 



I bred several of this insect from larvae collected by 

 Mr. Winter and myself at Ramworth at the end of April ; 

 they were mining the leaves both of Car ex paniculata and 

 Carex paludosa f simultaneously with the larvae of Elachista 

 Gleichenella. The specimens thus obtained, when placed 

 beside a series of Rhynchosporella and Eleochariella y ap-
