the three species of moths, two were not found in the vicinity 

 of the Straits. 



The other list is from Huron Mountains, Marquette County. 

 In 1919 A. W. Andrews collected some Lepidoptera there 

 early in July, and Bryant Walker added some specimens later 

 in the season. In 192 1 T. H. Hubbell collected some speci- 

 mens. The compiled list contains 19 species of Rhopalocera 

 and 22 species of Heterocera. Five species of moths in this 

 list have not been taken in the vicinity of the Straits. 



Considerable care has been taken in the determination of 

 the specimens. For much valuable assistance in this work I 

 am deeply indebted to Dr. W. W. Newcomb, of Detroit. He 

 has checked practically all of the determinations and has 

 devoted considerable time and the use of his extensive library 

 to the work. Where there exists any doubt in regard to the 

 identity of a species, it has either been omitted from the list 

 or a note of explanation has been made. The list includes 

 but 20 species of the super- family Tineoidea. A number of 

 other species have been taken, but the literature and the time 

 necessary for their determination has been lacking. In addi- 

 tion to 32 undetermined species of this group, the collection 

 contains 10 species of Noctuidae and 7 species of Geometridae 

 which have not been determined satisfactorily. 



The nomenclature of the Check List by Barnes and McDun- 

 nough, published in 19 17, has been followed in the list, with 

 one or two changes in conformity with later publications by 

 the same authors. The list indicates the counties in which 

 specimens of each species have been taken and gives the 

 earliest and latest dates on which each species has been taken 

 in any of the counties. 



A comparison of this list with others previously published 

 may be of interest. In the Fourteenth Report of the Michigan
