3. Note on the Genus Epyris. — Having erroneously de- 

 scribed and drawn another species under the name of Epyris 

 niger, I wish to correct the mistake ; which I am now enabled 

 to do, through the liberality of the Rev. G. T. Rudd, who has 

 supplied me with a beautiful series of specimens of the latter.
