TBE CANADIAN ENTOMOLOGIST. 71 



given by Prof. Fernald in Can. Ent., Vol. x., No. 5, for the collection of 

 Tortricidce, will apply equally well to the Pterophoridx. 



I desire to express my obligation to Prof. Fernald, who first suggested 

 to me the idea of making a special study of this group, and who has 

 granted me the free use of his valuable private library, and greatly aided 

 me in other ways. I am also much indebted to Prof. P. C. Zeller and 

 Lord Walsingham for aid in determination of species and advice during 

 the prosecution of my studies of this group. To the entomologists and 

 collectors who have assisted me in procuring material I likewise desire to 

 render my thanks. To Mr. Henry Edwards in particular I am under 

 obligation for the loan of his entire private collection in this family, com- 

 prising many beautiful species, mostly obtained in California and Oregon.
