My friend. Dr. Charles P. Alexander, visited the Island 

 about 12 years ago, and for the past 3 years has come with 

 our friend, Mr. Walter Harrison, the botanist, in order to 

 check up the Tipulidae. Some of the best times I have had 

 have been their visits and our collecting trips, and the fact 

 that Doctor Alexander has shown such an interest and written 

 everything connected with that family, gives it the stamp of 

 authority. 



Dr. A. E. Brower of the Maine Forest Service has shown 

 great interest in the work and has contributed many records 

 taken through his breeding experiments on the parasitic 

 hymenoptera and has also furnished many records of other 

 species as well as material. Being an expert lepidopterist, 

 the material in that order has had the advantage of his work 

 in collecting and also determining species, which accounts for 

 its being such a well-represented group. He is indicated in 

 the text by (Br.). 



Mr. C. A. Frost, Honorary Curator of Coleoptera, New 

 England Society of Natural History, has shown his usual 

 interest in promoting anything that has to do with entomology, 

 and no matter what I have asked him, or when it was asked, 

 he has been most kind in determining species. I give him my 

 hearty thanks. 



To the New England Society of Natural History I am in- 

 debted for the loan of books, and to their librarian. Miss Mary 

 B. Cobb, who has the true understanding that a library should
