XANTHCECIA BUFFALOENSIS GRT., ITS LARVAL 



HABIT AND OCCURRENCE WITHIN OUR 



FIFTY-MILE FAUNAL ZONE. 



By Henry Bird^ 

 Rye, N. Y, 



The keen powers of discernment possessed by the late A. R. Grote 

 have been generally impressed on subsequent students of the Noc- 

 tuidse, whenever his species are involved. Though he described a 

 unique example of Xanthoccia (Ochria) bnffaloensis many years be- 

 fore (1877), his recollection of details remained clear to him, and 

 after his departure from America to Hildesheim, our correspondence 

 frequently referred to this species for he was fond of this and allied 

 genera. He was wont to remark that once having studied a species, 

 its features were always distinct in his memory, which was born out 

 by his recollection of this moth though he had not seen his type for 

 a decade. His specimen came from Buffalo, N. Y., as indicated by 

 the name. Twenty-two years later one from Chicago, as then only a 

 second example apparently, was re-described by Strecker as Hydroccia 

 latia, the small tubercle on the frons being overlooked by him.
