Extract

In the writer's treatise on the North American species of the genus Aeschna (Walker, '12) the nymph of A. juncea L. was described from exuviae collected by the late Dr. F. Ris at Cierfs, Switzerland. One of the exuviae was accompanied by a teneral imago. A single female exuvia from Nipigon, Ont., very closely resembling the Swiss specimens, was tentatively referred in the same work (p. 98) to A. subarctica Wlk. rather than juncea, although both species were flying at the spot where the exuvia was found.
