them specifically aud feel confident that, notwithstanding the individual 

 variation in the number and size of the black spots on the posterior 

 wings, there is but one species to be considered. The larva, like most 

 of its family associates, is essentially polyphagous and feeds readily on 

 a variety of herbs as Ghenopodmm alburn^ Simploa/rpus fcetidus, etc. 

 I regard it as subject to considerable variation of coloration and per- 

 haps of ornamentation, which would satisfactorily account for discor- 

 dant diagnoses.

 Catocala subnata, nov. sp. (Plate 4, fig. 5. %.) 



S . Anterior wings greyish, ftiintly shaded with pale greenish ; trans-

Closely allied to C. neogama A. & S. ; the expanse is greater and the 

 body appears proportionally slenderer; the subreniform spot is sur-
