PRELIMINARY NOTES ON THE ODONATA. 91 
SUB-FAMILY AGRIONINAE. 
Genus Lestes Leach. 
L. eurmus Say. Will probably be found occasionally over the 
southern counties of Minnesota. It was taken in June, 1909, on Lake 
Okoboji in Dickinson County, Iowa, and Muttkowski states that it is 
found in western Wisconsin. 
L. inequalis Walsh. Wilson records two specimens from near St. 
Paul, and at Red Wing, Goodhue County, “Both sexes common in 
shady places near the woods.” 
L. unguiculatus Hagen. This seems to be the commonest Lestes 
in southern Minnesota. At Mankato, and on Lake Madison, Blue 
Earth County, the author has collected hundreds of specimens during 
late May, June, July, August and early September. It is an inhabitant 
of pond and small lake regions and is very seldom seen about streams. 
Wilson’s list does not show a single occurrence along the Mississippi 
River. It seems clear that great numbers of this species migrate from 
pond to pond or lake to lake during the breeding period, ovipositing for 
a day or so at each stopping place. Incomputable myriads of copulat- 
ing pairs will one day cover the rushes of a swamp, and on the follow- 
ing morning but a few scattered pairs will remain. 
L. uncatus Kirby. The only records of this heavy bodied, bright 
colored Lestes are from Manakto, Blue Earth County, and Alden, Free- 
born County. Three pairs were collected in the latter locality June 
10-15, 1914, by Miss Anna Holgersen. Uncatus is often found at 
considerable distances from water. 
L. disjunctus Selys. This species is included as a possible Min- 
nesota form on the strength of collections made by the writer at Spirit 
Lake, Iowa, in July, 1909. It is never a common species. 
L. forcipatus Rambur. Lestes forcipatus Rambur was taken at 
Mankato on July 13 and 20, 1913, and at Lake Madison, August 4- 
11,1914. It was fairly abundant during July, though copulation seemed 
to occur more freely on the later dates. This was also found true in 
studying the Iowa fauna. 
L. rectangularis Say. Two males only of this form were collected 
at Lake Madison, August 4-9, 1914. Both Wilson and Muttkowski 
record it for western Wisconsin and the writer has taken it in several 
Iowa localities. Lestes rectangularis frequents lakes, rivers and even 
woods. It is not common to the Lower Austral. 
L. vigilax Selys. “Both sexes found in tall weeds and grass back 
from the water; not very common.” Reed’s Landing. Wilson. 
Also recorded Lake Phalen, Ramsey County. It is a very common 
species in Wisconsin.
