J 50 LEPIDOPTERA. 



on which the mistletoe grows, but if disturbed darts at once 

 to the ground. So far as it is at present known found 

 almost exclusiveljr in orchards. It was first noticed in the 

 year 1878 by Dr. J. H. Wood on apple-trunks in Hereford- 

 shire, and in 1892 its larva was discovered in the same 

 orchard by that keen observer. Although easily reared, and 

 not difficult to capture, I do not find that it has as yet been 

 recognised in any other part of these Islands or abroad ; yet 

 Professor Zeller informed me that except in the colour of the 

 hind wings it agrees verj^ accurately with a North-American 

 species — B. alheolana.
