NEW RECORDS OF WISCONSIN DRAGONFLIES. 

 By Richard A. Muttkowski. 



The interesting material secured by. the St. Croix Expedition 

 of the Milwaukee Public Museum, together with a number of 

 records obtained by the museum through purchase of a collection 

 of Lepidoptera, which included a few Odonata, form a series of 

 records for students of distribution. While neither collection was 

 very thorough owing to the different bent of the collectors, some 

 conclusion as to the general faunal aspects of the region is 

 possible. Thus, the St. Croix material, at least that which was 

 collected in the first lap, shows decided boreal leanings, which 

 suggests a continuation of the Lake Superior strip of the boreal 

 region down the St. Croix River. Farther south, below the St. 

 Croix Dam, the material is more transitional in character. 



The Howieson material — (I prefer to designate thus briefly 

 the purchased material by the collector's name), as far as it is 

 from Wisconsin, is wholly from Chippewa Falls, in the midst of 

 the Transitional region. Although I have examined all the Wis. 

 Odonata of this collection I cite only the more important records. 



In addition, occasional reference is made to several minor lots, 

 from various localities, chiefly Cedar Lake, Washington Co., col- 

 lected by Dr. S. Graenicher, and Milwaukee and its surroundings. 



The asterisk before a species signifies that the species is new 

 to state lists.
