60 OBSERVATIONS ON BRITISH TINEINA. 



Pterophorus brachydactylus. Professor Frey finds the 

 larva of this (with us, great rarity) on the underside of the 

 leaves of Prenanthes purpurea, in fir woods, in May ; that 

 plant is not British, but is not unfrequently found in woods 

 escaped from cultivation. 



Pterophorus tephradactylus. Professor Frey finds the 

 larva of this on Solidago virgaurea in May ; I met with the 

 young larvae on that plant, at Clovelly, in September.
