NYSSIA Dup. 



LAPPONARIA B. Very rare. Nemoral. 



Distribution — East, o o Tay o o o o o 



West, o o o o o 



Lat. 56°4o'. Range in Europe. Lapland, Eastern Swit- 

 zerland (Upper Engadine), and Scotland. Type. Boreal 

 and alpine. Type in Britain. Scottish. 



Time of Appearance. — Imago. March. Larva. Food- 

 plant. 



A single specimen has been reported from Rannoch, and by many is con- 

 sidered of doubtful authenticity. I think it is probable that some insect 

 was really captured, but whether the specimen in question belongs to 

 lapponaria, or whether it was the commoner pomonaria, I am not in a posi- 

 tion to decide. 



Mr. J. B. Hodgkinson records (in Zoologist, 686) the occurrence of larvae, 

 supposed to be those of Nyssia zonaria, feeding on burdock on the summit 

 of Ben Beckley, Skye. Perhaps some one who has the opportunity will 

 try and solve this enigma by finding and rearing the larvae in question.
