with Gelechia liturclla Walker,* and with Hyale coryliella 

 Chambers. f 



The National Museum possesses a specimen which has been 

 compared with Clemens' type. 



Nepticula rubifoliella Clemens. 



One type, lacking the right fore wing, Clemens' No. 113 ; alar 

 exp., 4 mm. 



I have not bred this species and am at present unable to give 

 an opinion on the synonymy with the European Nepticula an- 

 gulifasciella, which Clemens suggested. 



Opostega albogaleriella Clemens. 



One type, Clemens' No. 120; alar exp., 5.7 mm. 



I have collected this species repeatedly at light in the District 

 of Columbia. Clemens' description does not mention the apical 

 costal and dorsal streaks, but they are present in his type, though 

 very faint, because the specimen is rubbed. Nevertheless, Frey 

 was fully justified in separating his Opostega accessoriella\ from 

 Clemens' species, from which it differs by the dark dorsal spot ; 

 but Frey evidently did not know of Chambers' Opostega quad- 

 ristrigella. It is the same as Frey's species, as the description 

 shows. 



Of the two remaining American species placed in Opostega, 

 nonstrigella Chambers is the only one that truly belongs to this 

 genus. It differs from Clemens' species by the dark dorsal patch, 

 and from quadristrigella by the absence of apical markings. 

 fiosquella Chambers is, as originally described by Chambers, || 

 a Nepticula and is the same as that previously described by Zel- 

 ler as Trifurcula obrutclla^ as the type of this species in the 

 Cambridge Museum proves. 



Representatives of all these species, collected by the writer in 

 the District of Columbia and in Kentucky, are in the U. S. National 

 Museum. 



Trichotaphe alacella Clemens. 



One type, Clemens' No. 115 ; alar exp., 13.5 mm. 



This type confirms the present conception of this well known 

 species. Specimens compared with it are in the U. S. National 

 Museum. Gelechia ochripalpella Zeller,** a.\\d Gelechia good- 

 elliella Chambers, f| are synonyms of this species.
