Parectopa lespedezaefoliella Clemens. 



One type, without wings on the right side, Clemens' No. 106 ; 

 alar exp., 7 mm. 



Lord Walsingham has made* Clemens' Parectopa robiniella 

 a synonym of this species as well as Gracilaria mirabilis 

 Frey and Boll. My examination of Clemens' types of these two 

 species does not tend to confirm this conclusion. In fact I think 

 the differences pointed out in Clemens 1 description fully borne 

 out by his types. However, not having any bred specimens of 

 lespedezcefoliella^ I prefer to leave the synonymy as it is. The 

 genus Parectopa may yet be adopted ; but in the meanwhile 

 the species may be known as Gracilaria Icspcdezcefoliella 

 Clemens. 

 Bucculatrix pomifoliella Clemens. 



One good type, Clemens' No. 107 ; alar exp., 7.5 mm. 



This represents our common apple Bucculatrix* described 

 subsequently by Packard as Lithocolletis curviliniatella. Bred 

 specimens, compared with the type, are in the U. S. National 

 Museum. 

 Bucculatrix agnella Clemens. 



One type in rather poor condition and lacking the left wings, 

 Clemens' No. 108 ; alar exp., 7 mm. 



I have not discovered any specimen of this species in the 

 U. S. National Museum. 

 Machimia tentoriferella Clemens. 



One type, lacking left wings, Clemens' No. 109 ; alar exp., 25 

 mm. 



This is our well-known species, described later by Chambers 

 as Depressaria fernaldella.\ Lord Walsingham has madej 

 Depressaria confertella Walker a synonym of this species. 

 During a visit at the home of Prof. C. H. Fernald, I saw two 

 specimens in his collection, not of this species, which Prof. Fer 

 nald had compared with Walker's tvpe in the British Museum 

 and which he has identified as confertella Walker. They cer 

 tainly agree better with Walker's description than does Machi 

 mia tentoriferella Clemens. They agree well with Zeller's de 

 scription of Cryptolechia ferruginosa, and I believe they are 

 that species, in which case the name ferruginosa would fall for 

 the older name confertella Walker. At present, however, before 

 Walker's type has been re-examined to find which of the two 

 gentlemen was right in his determination, it is proper to leave 

 the synonymy as first determined. A large series, identical with 

 Clemens' type of Machimia tentoriferella, is in the U. S. Na 

 tional Museum.
