OF WASHIX<;T<>X, vm.i'MK xi, 1909. 103 



in New York, has long been known to me in nature and the 

 recording of its food plant will materially aid in its future 

 recognition. 



The larva makes a small, very pale straw-colored upper 

 mine in leaves of oak around Washington. The mine is nor- 

 mally placed at the edge of the leaf and frequently causes the 

 edge to bend over in a small fold. 



The species has several generations in this vicinity ; the first 

 mines collected in early April, 1900, produced moth the same 

 month and others were bred in July and August.

The above names apply to the same species. The unique 

 female specimen on which Lord Walsingham founded his 

 genus Pseudoxylesthia had lost its head and had through a 

 mistake of the preparator been supplied with a head of quite a 

 different insect, as we discovered on closer examination at 

 Merton Hall last summer. This accounts for the discrepancies 

 between the generic descriptions.

The writer must take the blame for the fact that Mr. H. Engel 

 redescribed this species and thus created a synonym. Doitglasia 

 obscnrofasciclla was at the time not recognized, but there can 

 be no doubt that the two names apply to the same species, 

 which is congeneric with and specifically very close to Tinagma 

 pcnlicclliiin Zeller, of Europe. Chambers gave a very good 

 drawing <>f the unique venation of this genus.
