A new Halesidota collected by Professcr Snow. 

 By A. E. Grote. 



The collections made of late years by Professor F. II. Snow in 

 different departments- of Natural History have largely encreased our 

 knowledge of our Western fruna. They have proved of great value 

 so far as Nocturnal Lepidoptera are concerned, while the material 

 collected in Colorado has enriched our catalogues with many forms 

 new to science and revealed many facts with regard to the geogra- 

 phical distribution of previously known species. Professor Snow's 

 labors will haA^e a permanent value in the field of Natual History 

 in America and their continuance is greatly to be hoped for in the 

 interest of science.
