 Probably more abundant with us than expected. Appears 

 generally to affect old gardens, where the red currant bushes (on 

 the medulla of which the larva feeds, passing, according to Dr. 

 Staudinger, one winter in that state; are knarled, and have been 

 long in cultivation. Newcastle. Darlington. — Wm. Backhouse^

Dr. Staudinger states that the larva lives over one winter. 

 It is found in the low trunks or branches of Salix triandra^ and 

 S. viminalis; rarely in S. alba. When young it lives in the 

 alburnum, but soon enters the wood, and is especially fond of 

 the small side shoots of the stems of these trees. 



Of the thirty-six British Sphingina we already number nine- 

 teen. Of the remainder, three at least are very doubtful natives 

 of these kingdoms, and several exist only in single cabinets. 

 Three or four additions, such as Anthrocera LonicercBj Smerin- 

 thus Tilia^^ and Sphinx Ligustri, are all we can expect to add 

 to our list, unless some of the birch or alder feeding species of 

 Trochilium should occur in the wilder parts of the counties 

 where these trees are found indigenous.
