ACKXOWLEDGMKNTS 



The value of any local list of Lepidoptera depends much 

 upon accuracy in identification. For this reason determina- 

 tions involving the slightest doubt have been indicated. The 

 writer wishes to express indebtedness to several specialists 

 and general lepidopterists for their kind assistance as follows : 

 to Dr. W. \\'. Xewcomb, of Detroit, for aid in identification 

 of many specimens and for the use of his private collection 

 and library ; to Mr. L. W. Swett of West Somerville, Massa- 

 chusetts, for identification of the difficult Geometridse; to 

 ^Ir. F. H. \\'olley Dod, of ^lednapore, Alberta, for identifi- 

 cation of the difificult Xoctuidcc; to Miss Annette F. Brown, of 

 Cincinnati, for identification of a number of Microlepidoptera ; 

 and to ]\Ir. Alexander Kwiat, of Chicago, for identification 

 of several specimens. Acknowledgments are also due to Mr. 

 A. W. Andrews who made collections in 1913 as previously 

 stated, and to both ■Mr. and Mrs. Andrews, j\Ir. Fenton Combs, 

 and ]\Ir. House and family, who kindly assisted in the field 

 and collected many specimens that would not have been ob- 

 tained otherwise. 



List of Species 



The following annotated list includes all the Lepidoptera 

 collected on Whitefish Point save the Microlepidoptera. Of 

 the latter, only the more readily determined species are listed, 

 so that much unidentified material remains in the collection 

 awaiting further work. •
