Enallagma signatum Hagen. Fort Myers, Florida, March 4 and 

 11, 1921, 3 $ ; Enterprise, Florida, April 16 and 20, 1921, 25,1 9 , 

 all by J. H. Williamson. At Fort Myers the specimens were col- 

 lected on a small creek just west of a cemetery about half a mile east 

 of town. At Enterprise the specimen taken April 20 was captured 

 at a small swamp on the south side of the railroad one mile east of 

 the station. 



In these Florida specimens the male superior appendages 

 are in every case slenderer than in all other specimens I have 

 seen. 







Enallagma pollutum Hagen. Miami, Dade County, Florida, Ever- 

 glades, January 23, 1899, S. N. Rhoads. 3 $ ; Fort Myers, Labelle, 

 Moore Haven, Palmdale and Enterprise, Florida, for dates see first 

 paragraph of this paper, J. H. Williamson, 313 $, 104 9, a few 

 tenerals and many pairs taken in copulation, most of the specimens 

 taken at Fort Myers, Moore Haven and Palmdale, while at Labelle 

 and Enterprise the total catch for both stations was 9 $ and 4 $ . 



At Fort Myers, Mr. Williamson noted: "Taken along 

 shady stretches of a small, mucky-bottomed creek where it 

 flows through orange groves. Easily caught as they rested on 

 green vegetation at the water's edge." At Moore Haven he 

 noted : ''Taken in large numbers along sun-exposed drainage 

 ditches; vegetation in water and on ditch banks scanty." And 

 at Palmdale : "Frequented floating, grass-like vegetation in 

 shallow, running water at shaded parts of Fisheating Creek." 

 Generally the Enallagmas of the pollntnui group are lake or 

 pond species; pollutum however seems to prefer streams. 



A pair taken March 30, 1921, at Moore Haven is preserved 

 with the male appendages in position grasping the female. In 

 these specimens, the apices of the male inferior appendages 

 are just above the dorsal prothoracic pits of the female, and 

 confirm Dr. Calvert's suggestion that the appendages, in copu- 

 lation, engage the pits. The externo-superior branch of the 

 superior appendage grasps the mesostigmal lamina of the 

 female, the anterior raised border of the latter fitting in the 

 concavity between the externo-superior branch and the intenio-
