296 Mr. H. T. Stain ton's Synopsis 



1. Elachista Quadrella, Hiibner. 



Readily distinguished by its large size and the position of the 

 silver spots. 



Expansion of the wings 5g lines. Head grey ; anterior wings 

 bronzy-brown, with four silvery spots, the first on the costa near 

 the base; the second on the fold in the middle ; the remaining two 

 are placed opposite one another beyond the middle, that on the 

 costa being rather the larger. At the base of the inner margin is 

 a silvery blotch. 



The larva mines the leaves of Luzula pilasa, making inflated, 

 puckered mines in May, and changes to a pupa within the mine. 



The perfect insect appears in June and July ; it occurs in Swit- 

 zerland, Ba~varia and Tuscany. 



2. Elachista Trnpeziella, Staintnn. 



Most nearly allied to E. Tetragonella, but larger and paler, and 

 the costal spot is opposite the spot on the fold. 



Expansion of the wings 4^ lines. Head whitish-grey ; an- 

 terior wings brown, with a short silvery streak along the fold at 

 the base; in the middle are two silvery spots, one on the costa, 

 the other on the fold ; at the hind margin are two other smaller 

 silvery spots, one at the anal angle and one at the apex of the 

 wing. 



The larva, which is spotted with red, mines the leaves o{ -Luzula 

 pilosa, making flat mines near the tip of the leaf, in June. 



The perfect insect appears in July ; it has occurred at West 

 Wickham Wood, near London, and at Zurich in Switzerland. 



3. Elachista Tetragonella, Herrich-Schaffer. 



Allied to the preceding, but the costal spot placed far beyond 

 that on the fold, and nearly opposite to that at the anal angle. 



Expansion of the wing 3 lines. Head black ; anterior wings 

 black, with a faint olive tinge, with four brilliant silvery spots, the 

 first on the fold before the middle, the second on the costa beyond 

 the middle, the third at the anal angle, and the fourth at the apex 

 of the wing. 



The larva, greenish with grey subdorsal lines, mines the leaves 

 of Carex montana, making long whitish blotches early in May. 

 The perfect insect appears in June ; it occurs in Switzerland, near 

 Zurich, and at Engelt)erg.
