I have not seen Scottish examples, but from what Mr. A. Davidson tells me I 

 hav^no hesitation in including roborls in this list. Mr. Davidson writes as 

 follows : — " 1 found the larvae of querczis in a plantation consisting principally 

 of larch, near Kerrisdale, Gairloch. They were feeding upon the sloe. I fed 

 them with it and had the satisfaction of seeing the moths emerge from their 

 cocoons in the latter end of July."]
