• of the Genns Elacfiista. 299 



The larva, which is pale whitish-yellow, of a duller white on 

 the back, feeds on various grasses, making flat whitish mines in 

 April and the beginning of May. 



The perfect insect appears in June, and seems abundant nearly 

 everywhere. It has occurred as far north as Finland, and as far 

 south as Tuscany. 



9. Elachista Cinereojmnctella, Haworth. 



By the fascia not reaching beyond the fold, and the position of 

 the costal spot at the apex of the wing, this species may be at once 

 recognised. 



Expansion of the wings 4 lines. Head grey ; anterior wings 

 dark grey (blacker in the J ) ; on the costa in the middle is an 

 oblique whitish spot, reaching to the fold ; beyond the middle are 

 two whitish spots, placed one at the anal angle, the otlier on the 

 costa at the apex. (In the ? these spots are very distinct and 

 quite white.) 



The larva is yellov^ish, whiter above, witli a row of red spots 

 on each side of the back ; it makes long brownish mines in the 

 leaves of Carex glaiica, and is full fed in April. 



The perfect insect appears at the end of May and in June ; it 

 commonly occurs on the chalk in the south of England, and in 

 various localities in the north of England and in Scotland ; also 

 in Switzerland at Zurich. 



10. Elachista Abbreviatella, Stainton. 



As in the preceding species the fascia sets off from the costa, 

 and does not reach the inner margin, so in this it sets off from 

 the inner margin and does not reach the costa. By (his character, 

 and by the unusual breadth of the anterior wings, this species may 

 be immediately recognised. 



Expansion of the wings 4^ lines. Head brown ; anterior wings 

 brown ; on the inner margin before the middle is a small yellowish- 

 white spot, which just reaches over the fold, but does not even 

 attain the middle of the wing ; beyond the middle are two yel- 

 lowish-white opposite spots, of which that on the costa is much 

 posterior and by far the larger of the two. 



Larva unknown. 



The perfect insect appears in June ; it has occurred on the 

 Austrian Alps, and at Reineiz in Silesia.
