The private collection of Prof. C. H. Fernald consists mainly 

 of Microlepidoptera comprising nearly all of the described 

 species of the family Pterophoridae of North America and 

 Europe and many from South America; all the types of Fitch 

 except one which is not in existence; all the types of Fish as 

 well as his own types and cotypes of nearly all of the species de- 

 scribed by Lord Walsingham from North America. It includes 

 about nine tenths of all the types of the described species of 

 North America belonging to this family. 



Of the Tineina it contains a large number of authentically 

 named species of North and South America together with all of 

 his own types, a large number of those of Chambers and Miss 

 Murtfeldt and cotypes of most of the species described from.

Of the Pyralidae it contains authentic specimens of nearly 

 all the described North American species, and many from 

 Mexico, Central America, the West Indies, South America, 

 Europe and other parts of the world; all of his own types and 

 many cotypes of Hulst and Grote. This collection is rendered 

 more valuable from the fact that the owner has compared it

 times as large as that of the Berlin or Vienna museums with 

 which it has been compared. It contains a very large number of 

 types and cotypes as well as homotypes having been compared 

 by the owner with nearh^ all of the Tortricid types in existence.
