Occasional Papers of the Museum of Zoology 5 



Academy of Science, 1912. Dr. W. W. Xewcmnb published a 

 list of the butterflies of ^Michigan, based on all earlier lists 

 and upon the results of his own collecting. This list contains 

 the names of loi species. In Entomological Xews, ^larch, 

 191 5, Paul vS. Welch published a list of Lepidoptera taken in 

 the vicinity of Douglas Lake, Cheboygan County. This list 

 includes but 26 species of butterflies, and adds no new species 

 to Dr. Xewcomb's list. In May, 1918, the University of Mich- 

 igan published a list of Lepidoptera from Whitefish Point, by 

 W. S. McAlpine, the results of the Shiras Expedition of 19 14. 

 (Occasional Papers of the Museum of Zoology, No. 54.) This 

 list includes 42 species of butterflies and adds two species to 

 Dr. Newcomb's list. In the present list there are 68 species 

 of butterflies, seven of which are not included in any previ- 

 ously published list. Two additional species have been taken 

 during the past season by Dr. Newcomb at Detroit. This 

 makes the total number of species of Rhopalocera known to 

 occur in Michigan 112. Of the total number of species 

 recorded from the state, 67, or about 60 per cent, occur in the 

 territory bordering the Straits of Mackinac. 



The species in the present list which have been included in 

 no previously published list are as follows : 



Zegris olympia rosa Edw. The onlyAspecimens known to 

 have been taken in Michigan were secured by X. A. Wood, 

 in Berrien County, in the spring of 1920. 



Coenonympha inornata Edw. Probably taken in Schoolcraft 

 County in 19 1 5 by W. S. McAlpine, although I have not seen 

 his specimens. 



A'athalis iole Bdv. One female was taken by T. H. Hub- 

 bell in Gogebic County. The occurrence of this southern 

 form in the Northern Peninsula is remarkable. 



Oeneis chryxus Dbldy. & Hew. Taken in only one locality
