184 ENTOMOLOGICAL SOCIETY 



The following are detailed statements of the number and con 

 ditions of these types, together with such notes on their syste 

 matic position and synonomy as are possible without mono 

 graphic studies of all the families. When such studies are under 

 taken additional changes will probably be found necessary. 



A serious drawback to the value of Clemens' descriptions was 

 his failure to give the size of his specitnenor the locality. In the 

 following notes the writer has given alar expanse of all the species 

 according to the measure of the type specimen, as well as the 

 locality of all those species of which he has seen other material. 



For several reasons it is found most convenient to treat the 

 species chronologically in the order in which they are found in 

 Stainton's edition of Clemens' North American Tineina. 



Tinea biflavimaculella Clemens. 



One perfect type, Clemens' No. i ; alar exp., 16.5 mm. 



Stainton, who received two specimens of this species from 

 Clemens, wrote in a foot-note in Clemens' Tineina of North 

 America : " It appears to be almost identical with the European 

 Tinea rusticella, var. spilotella Tengstrom," and Zeller* made 

 it a synonym of this species. Lord Walsingham corrected thisf 

 and I have no hesitation, after comparing a good series of bifla- 

 vimaculella with authentic European specimens of rusticella, 

 in agreeing with him that Clemens' species is quite distinct. 

 Walsingham established in the same paper the synonymy with 

 Walker's Tinea insignella.\ 



Biflavimaculella belongs to the genus Monopis, Hu'bner. A 

 specimen compared with Clemens' type is in the U. S. National 

 Mueum. 



Tinea dorsistrigella Clemens. 



Two perfect types, Clemens' No. 2 ; alar exp., 14.5 mm. 



This is, as Stainton suggested (Tin. N. Am., p. 50, 1872), a good 

 species, near, but quite distinct from, the European ferriiginella 

 Hu'bner. Walsingham has established its synonymy with Tinea 

 subjunctella Walker. Clemens' types are larger than average 

 specimens of this common species, of which a good series is 

 found in the U. S. National Museum. 



The writer has bred this species from larvse feeding in a bird's 

 nest. It belongs in the, genus Monopis Hu'bner. 



Tinea crocicapitella Clemens. 



One perfect type, Clemens' No. 3 ; alar exp., 14 mm. 



Lord Walsingham made this species a synonym of the European 

 ferruginella Hu'bner, and it has been retained as such in Riley's
