PROFESSOR FERNALD'S SYNONYMICx\L CATALOGUE OF 

 NORTH AMERICAN TORTRICID^. 



BY A. R. GROTE. 



t 



The reader of the Canadian Entomologist will recall the first paper 

 on the Tortricidce, by Professor Fernald, who has been kind enough to 

 send me advance sheets of his Catalogue of the Family now being pub- 

 lished in Philadelphia. 



At the time when Professor Fernald commenced his studies he paid 

 me the compliment of asking my advice as to the group of Lepidoptera 

 he should work upon. In advising him to take the TortricidcB, I was 

 influenced by my belief in his patience and scientific ability. No family 

 of Lepidoptera which I have studied, except perhaps the Phycidce, are as 

 diflicult as the Tortrices, or call for more diligent examination and careful 

 manipulation. I had been bringing together material for a study of the 

 Tortricidce, and had described a few species and the genus Phaecasiophora, 

 when Professor Fernald wrote to me. I was thus in a position to be of 

 the slight assistance which Professor Fernald has, I am afraid, over- 

 estimated in his original paper alluded to above. But it is difficult to 

 overestimate the importance of Professor Fernald's work and the excel- 

 lence with which it has been performed. With the valuable aid of Lord 

 Walsingham, Professor Fernald was able to examine personally almost 

 every one of Mr. Walker's types. The types of my friend, the late Mr. 

 C. T. Robinson, had been placed in Professor Fernald's hands before his 

 visit to London, and I had given him all the material brought together by 

 myself, so that no one was in so favorable a position for ascertaining what 

 had been described and what was yet new among our Tortrices. Every 

 American paper which I have seen on the family, since that time, has 

 been issued after the material on which it was based had been determined
