and those genera which they most resemble hi this respect, 

 it is not so easy to separate them, except by the characters 

 which the superior wings suj>ply. 



Many of the Tortrices are very destructive to plants, some 

 causing most extensive injury to the vines, especially in France; 

 others destroy our roses, and T. viridana sometimes com- 

 pletely defoliates our oak-trees. The caterpillars roll them- 

 selves up in the leaves, forming a tunnel open at both ends, 

 and when disturbed they wriggle out, being very active, and 

 fall down suspended by a thread, which enables them to re- 

 ascend when their alarm has ceased : they change to pupae 

 in the rolled leaf, the chrysalis being slightly held by a few 

 threads, but they vary considerably in their oeconomy.

First noticed by Mr. Bentley, who took it, I believe, at 

 Whittlesea Mere in July : I have captured both sexes on Par- 

 ley heath, also near Kenmare and Glengariff, and in the Isle 

 of Skye in August, where I observed the terminal shoots of 

 the Myrica spun together, probably by the larvae of this moth.

 The pilose antennae of the male will induce me to refer this 



species to my genus Jmphisa. 



The plant is Myrica Gale, Sweet Gale or Dutch Myrtle.
