Eeceived, with one or two other species, from Mr. Ed- 

 monds subsequent to the completion of my papers upon 

 the groups to which they were referable ; it comes nearest 

 to A. argyrina of Guenee from Monte Video, but the 

 latter species differs from it in having a broad internal 

 band on the primaries, " une large bande au bord interne, 

 d'un blanc d'argent brilliant," whereas in A.pura there 

 is only a slender abbreviated line.
