 Lestes disjunctus Selys. 



Maiden Rock, Pierce Co.. July 27-Aug. 3. one female; Aug-. 4-10, 

 one male. 

 Lestes vigilax Hagen. 



Golden Lake, Waukesha Co., July 7, 1910. Male and female col-

The measurements of the specimens: Abd. male 37, female 

 2,7, hind wing male 25, female 28, are unusually large, especially 

 for the female, which is the largest I have thus far seen recorded.

 apical segments, as also the yellow or brown stigma, render this 

 species easy of determination. 

 Lestes eurinus Say. 



North Hudson, St. Croix Co., July 6-12, one female. 



While normally the wings are infumated, this specimen is 

 clear winged.
