46 , IN MEMORIAM. 



ground colour is a very shining, silvery-golden fascia, which, 

 on account of the narrowness of the wings, is nearly as broad 

 as long, and forms therefore a nearly quadrate spot, a little 

 attenuated posteriorly. The black space which precedes the 

 fascia is nearly as broad as it. The cilia broad, grey. 

 Posterior wings and their cilia grey. 



Thorax coppery-red. Abdomen black with a metallic 

 gloss and the anal tuft reddish. Tarsi clothed with [grey 

 hairs. 



The colour of the head is alike in both sexes ; but amongst 

 them I bred one small female specimen, in which the front 

 part of the tuft is ferruginous. 



This species is distinguished from all with which I am 

 acquainted, by the extraordinarily long and narrow anterior 

 wings. 



The larva is shining, unicolorous, brownish-yellow, witli 

 the head and second segment more shining and rather 

 darker ; on the head we see, as in the allied species, two 

 diverging darker lines, and the mouth is also darker. 



I found the larva at the end of October, on the Bergstrasse 

 at Jugenheim, on hill slopes, on wild plants of Fragaria 

 vesca growing in the shade. But I fancy I also have seen the 

 mines of this species at Frankfort and in the Black Forest, 



The mines are very long, many times twisted here and 

 there ; they begin very fine, and then for a considerable 

 distance retain the same width ; they are yellowish-grey, 

 with a darker excremental track in the middle. Sometimes 

 two or three larvae mine in the same leaf, and then the 

 mines form a dense tangle. 



The cocoon is oval, rather flat, pale brown. It is often 

 attached by the larva to the underside of the leaf. 



I bred the imago in the warm room as early as the end of 

 March. (1861.)
