Tiirce s])ecies of surpassing bciiuty constitute tliis genus, but 

 one of them has not yet been found in Britain. Tlic larv;c of 

 none arc liiown ; but the larva of Brurelld is pretty strongly 

 suspected: it mines in the leaves of the h()[) in September, when 

 full fed (luitting the leaf and forming a hue white cocoon, witliin 

 "which the larva remains unchanged during the winter, hence the 

 perfect insect is difFicult to rear. Mr. Douglas had collected a 

 number of these larvre in the autumn of 1852, but many escaped 

 from his breeding cage, and the remainder died ; in the following 

 July he found a specimen of the ])erfect insect on the window of 

 the room where he had kept his larvtc; subsequently ^fr. Wing 

 discovered some of the perfect insect (not previously known to 

 occur in this locality) by beating the hop-plant, the leaves of 

 which had furnished the mining larva; the previous autumn. I 

 therefore conclude that these miners are the larva) of Dnirella, but 

 that they are so is not yet proved.

Truly, as llaworth says, "species formosissima;" it has oc- 

 curred in some plenty in several localities near London in July; 

 it was reputed to frecpient a willow-tree at Hackney, probably 

 because some hops grew in the vicinity.
