The insect has a somewhat more hirsute appearance than 

 vinctilella, H.S., for which it might easily be mistaken were it not for 

 the very stout and differently formed antennae which at once dis- 

 tinguish it. A specimen in the Zeller Collection from Helvetia was 

 placed in the series of argentimaculella, Stn., and two specimens in the 

 Christoph Collection were erroneously placed in vinculella, H.-S.

This species was described by Zeller in a paper, entitled, " Beit- 

 rage zur Kenntniss der nordamericanischen Nachtfalter, besonders 

 der Microlepidopteren," and was, perhaps not unnaturally, included 

 by Chambers in his Index to the described Tineina of the United 

 States and Canada. This was, however, an error, for Zeller wrote, in 

 reference to the habitat of this species : " Es wurde nebst mehreren 

 von Christoph bei Sarepta am 10 August gefangen." Blastohasis 

 segnella must be removed from the North American Catalogue, and 

 included in that of Europe.
