Me3'rick, who, by return mail, pronounced it to be solanella Boisduval, 

 which name must fall for the earlier one of Zeller. 



Zeller described two females, which he associated with this species 

 with some doubt; it seems evident from his remarks that these two 

 female "types'' are really another species, as Zeller himself surmised. 

 They are, with one male, in the collection of Lord Walsingham 



The species, which likel}^ has its original home in America, is now 

 introduced in Europe, Africa, and Australia, and is of some economic 

 importance, owing- to the damage to tobacco and potato crops accom- 

 plished by it. 



The difi'erent life modes on the two food plants, as leaf min(>r on 

 tobacco and as borer in the potato, are equally well known and have 

 been the subject of a large amount of literature in economic ento- 

 mology, references to \7hich are not attempted here. Among the 

 most important are those of Dr. L. O. Howard.^ 



In the U. S. National Museum are bred sj)ecimens compared by the 

 writer with Zeller's t} pes and many specimens determined by Lord 

 Walsingham as Gelechia Holanelhi Boisduval, besides a very large 

 series l)red from tobacco and potato in the insectary of U. S. Depart- 

 ment of Agricidture.

Phthorimsea glochinella Busck, Dyar's List Amer. Lep., No. 5617, 1903. 



This is the smaller and plainer species bred b}- Miss Murtfeldt from 

 Solanum and mixed up l)y Chambers with his similiella (p. 779). In 

 the U. S. National Museum is a specimen named by Lord Walsing- 

 ham Gelechia (flocJilnella; also a large bred series received from Miss 

 Murtfeldt. 



The male genetalia as figured hy Zeller is the surest distinguishing 

 character from the preceding very similar species.
