Since describing the <ibove I received from this Society a case of Het- 

 erocera to determine and found several individuals of this species among 

 them, which approach more nearly to the European II. m-nu'gera and make 

 it probable that this is the species regarded by Guenee as identical with 

 the latter. 



The discovery of the larva might prove our species distinct from the 

 European, but judging from a series of perfect individuals it must be re- 

 garded as identical. The specimen from which I made the description 

 presented differences which, when compared with a European specimen. 

 I regarded as specific ; with a larger series of individuals before me I am 

 inclined to regard them as constituting a mere variety. This species 

 should be catalogued as above. It is not enumerated in Morris's Cata- 

 logue published by the Smithsonian Institution.
