OBSERVATIONS ON TINEINA. 155 



" In the middle of -winter I brought the pupae into the 

 heated room, and the moths made their appearance in about 

 two (?) weeks." 



" * Swammerdaviia conspersella, Tengstrom. The larva of 

 this species feeds (in June ? ) on the crowberry {Empetrum 

 nigrum), amongst which it forms a web with fine white 

 threads, and, in the middle of this, it prepares itself a case-like 

 cocoon for the small pupa. I found it very plentifully at 

 Pichtendahl on a dry moor."
