from the mainland, are geographically a part of Emmet 

 County, heing a continuation of Waugoshance Point, but for 

 political reasons they are attached to Charlevoix County. 

 Beaver Island, the largest of the group, was scarcely touched, 

 a little collecting having been done near St. James only. Gar- 

 den Island, the second in size, about five miles long by two 

 miles wide, was thoroughly covered in 1919. The beaches of 

 this island are for the most part rocky, and behind them is 

 the usual growth of conifers. The interior of the island, 

 however, is high, and covered with a heavy growth of maple, 

 beech, and birch. There are several old clearings and some 

 small lakes. This island affords the most diversified habitat 

 of any territory along this portion of the lake, and is an excel- 

 lent collecting ground. 



Hog Island, somewhat smaller than Garden Island, is low 

 and flat, and covered with a dense growth of mixed timber. 

 There are a few sand ridges near the northern end and a 

 black ash swamp of considerable size in the interior. It was 

 thoroughly covered during the season of 1920, but ofifers little 

 to the collector. The other islands of the group. Squaw, 

 Whiskey, and Hat, are all small, low, and rocky, with a scanty 

 growth of mixed trees. Hat Island, the smallest of the three, 

 is a breeding place of the herring gull and the great blue 

 heron. 



Combined in this list with the results of the writer's collect- 

 ing along the Straits of Mackinac are two small lists of Lepi- 

 doptera from different localities. In July, 1919, T. H. Hub- 

 bell was sent to Gogebic County to collect Orthoptera for the 

 Museum of Zoology of the University of Michigan. In the 

 course of his work there he took 13 species of Lepidoptera. 

 Ten of these species were butterflies and included one speci- 

 men of Nathalis iole Bdv., which is a record for the state. All 

 of the other species have been taken along the Straits. Of
