Hydriomena Hiibner 



This genus has been revised so recently that I have been unable to verify the NY 

 records. Only the following can be treated as certain. 



4015 H. frigidata Wlk. "NY", May (B&McD). 



4016 H. transfigurata Swett. McLean Bogs, May (male).

4017 H. renunciata Wlk. Peru; E. Aurora (Wild) ; McLean (Fbs) ; LI: Central 



Pk., Kch (Fbs). Late Je-Jl. This is the American representative of 

 autumnalis (coerulata). A member of this group occurs at Saranac 

 Inn. 

 4024 H. ruberata Freyer. McLean (Fbs); Ithaca; Big Ind. Val. (not verified, 

 but undoubtedly correct). May.
