the antennas nearly as long as the wings, not separated by the legs or 

 tongue ; labial palpi covered, and maxillary palpi absent. The head- 

 sclerites are of gelechiid type ; cremaster without spines or hooks ; and 

 frontoclypeal suture absent. The body is roughened with rounded

APHELOSETIA Stephens 



(Elachista Treitschke, in part; Cosmiotes Clemens; Eurynome Cham- 

 bers, not Leach ; Busckia Dyar, Phigalia Chambers, not Duponchel ; 

 Aphigalia Dyar) 



The characters are given in the description of the family. There is some varia- 

 tion in structure, especially in venation, but it is not large, and as there is some 

 confusion in names no attempt is made here to divide the genus. Elachista con- 

 colorella Chambers is an Eriphia, but is not the Eriphia concolorella described 

 by him on the same page. E. orichalccllu, Dr. Braun informs me, is also a 

 Cosmopterygid.
