This large and handsome species was common at Saranac Inn 



about the edges of all sphagnum-bordered ponds, where it was 



associated with L. u n c a t a and L. unguiculata, and 



with other genera. I bred it there on June 20, 1900, and again 



at Lake Forest 111., where it is rather uncommon, on June 12, 



1901.
