Solon Springs, Douglas Co.. July 7-15, 1909 ; 2 males. 



St. Croix Dam, Douglas Co., July 17-22, 1909 ; 9 males, 3 females. 

 Both Calvert (Biologia Centralia Americana) and Bis (Catalogue 

 Collections Selys) have rejected Needham's genus Laclona. Calvert 

 finds a "variation of 20% toward Libellula", as the type of which he 

 designates L. quadrimaculata. This is contrary to Kirby and Selys 

 (L. depressa,) whom I have followed in my catalogue. Hence a com- 

 parison between a series of the type species of Libellula and Ladona 

 must be the final criterion for the rejection or retention of the genus 

 Ladona. 



Libellula Iuctuosa Burmeister. 



Cedar Lake, Waschington Co., Aug. 30, 1909 ; 1 male. 



Perithemis domitia Drury. 



Cedar Lake, Washington Co.. Aug. 21, 1909 ; 1 male. 



Sympetrum obtrusum Hagen. 



St. Croix Dam, Douglas Co., July 17-22, 1909 ; 8 males. 

 Cedar Lake, Washington Co., Aug. 21, 1909 ; 2 males ; Aug. 29, 

 1 male ; Aug. 30, 2 males, 3 females. 



Sympetrum vicinum Hagen. 



North Hudson. St. Croix Co., Aug. 13-14. 1909 ; 2 males, 5 females. 

 Cedar Lake, Washington Co., Aug. 30. 1909 ; 1 male. 



Sympetrum sp. Muttkowski. 



North Hudson, St. Croix Co., Aug. 13-14, 1909 ; 1 male. 

 This is identical with the specimen from Fox Lake. Dodge Co., 

 which I noted in the Bulletin of this Society (Vol. 6, p. 167, 1909). 

 Like that specimen this male is also a teneral. and differs from normal 

 forms of $. costifemm, only in the number of denticles on the superior 

 appendages and the entirely black tarsi. Both resemble teneral $. 

 costiferum in that the costal area of all wings is flavescent. 



Celithemis eponina Drury. 



Cedar Lake, Washington Co., Aug. 30, 1909 ; 1 male. 1 female. 



Leucorrhinia gSacialrs Hagen. 



St. Croix Dam, Douglas Co.. July 17-22. 1909 ; 15 males. 7 females.
