the vertebrates by modern science. We are thrown for our surmises upon 

 the structure of existing forms, and this very alkiring study I have 

 endeavored to give a sketch of in the present chapter. I repeat what I 

 have often said, that only by such views of the Lepidoptera, such higher 

 uses to which we may put our knowledge and observations, do we relieve 

 the study from the charge of triviality, a mere sorting and arranging of 

 objects which is pursued by some even to the elimination of aesthetic 

 amusement and pleasure, and degenerates into a mere storing up of speci- 

 mens rare and difficult to obtain, and panders to the strictly selfish pas- 

 sions of the human heart.

NOTE ON AGROTIS HOSPITALIS. 



BY A. R. GROTE. 



Having recently, through the kindness of Mr. W. VV. Hill, the well 

 known Lepidopterist, been able to carefully compare my type of hospitalis 

 with a series of Agrotis perconflua Gr., I believe we have to do with a 

 variety of this latter species differing by the black marked t. a. line, the 

 black edging on costal region of t. p. line, the more suffused and deeper 

 color. The insects are structurally identical, and although variation in 

 these points is not usual (I have not met with it), yet the perfect corre- 

 spondences in other points carry the conviction that in hospitalis from 

 Lewis Co., N. Y., we have only a ioxxa. oi perconflua. These more 

 northern forms of the genus, viz., Hilliana., cojiflua, perconflua, and 

 rubifera, are related to our common New York species, A, Fhyllophora, 

 and the Californian A. Rosaria, as well as to several European species of 

 the genus Agrotis.
