18 IN MEMORIAM. 



It forms an oval, firm cocoon, mixed with earth, to 

 undergo its change to the pupa state. 



The imago appears at the end of July. (1836.) 



Depressaria parilella, F. R., Heyden (1861, p. 34). 

 The larva occurs singly on Peucedanuni oreoselinum in the 

 woods at Mombach, near Mayence. It spins the leaves 

 together to a rather large, diffuse ball-like web, in which it 

 changes to pupa at the beginning of June. 



The imago appears at the end of July. (1855.) 



Depressaria emeritella, Heyden (E. Z. 1861, p. 35). 

 The larva occurs round Frankfort at the end of July 

 between the united leaves of tansy {Tanacetum vul^at^e), 

 and is very lively. It assumes the pupa state in its domi- 

 cile, and the imago appears in the middle and end of August, 

 also singly at the beginning of September. (1820.) 



Enicostoma lobella, S. v., Heyden (E. Z. 1863, 

 p. 343). The larva is found from the beginning to the 

 middle of August on sloe (^Prunus spinosa) ; it forms a 

 thin white web (beneath which it lies) on the underside of 

 the leaves, which hence are arched longitudinally. It is 

 very lively and wriggling. It forms a firm, narrow, oval 

 cocoon in which it changes to the pupa state. 



The imago apj^ears at the beginning of May and is abun- 

 dant in this neighbourhood. (1825.) 



Gelechia ferrugella, S. v., Heyden (E. Z. 1861, 

 p. 35). I found the larvae at the end of May in the wood 

 at Falkenstein on the Taunus in poddike or tubularly united 

 leaves of Campanula i^^rsicifolia. It is extremely lively.
