Including the synonymy as worked out by Doctor Dyar, a which 

 I am pleased to adopt in full, with the exception noted below, the 

 above list accounts for all North American species referred to this 

 genus except the names under No. 5010 of Doctor Dyar's list, which 

 have been the cause of some misconception in the past. Chambers's 

 Anesychia texanella 1 was naturally placed in the genus Ethmia 

 (Psecadia) by Lord Walsingham on the evidence of Chambers's de- 

 scription and generic name, and i( lias been retained in this genus 

 since; but Chambers himself expressed a doubt, and his unquestion- 

 ably authentic type in the Museum of Comparative Zoology in Cam- 

 bridge proves it to be a large Gelechia species near harnesiella Busck.
