Abstract

Breeding at Go Home Bay confirmed what had already been suspected from our collections and breedings in the Ottawa and Knowlton regions, viz , that the nymph and female imago referred to by Clemens under the name flavescens belong to the species, ruber McD. Nymphs were secured at the Flat Rock Falls, the identical locality where they had been collected by Clemens, and two males, three females bred through to the adult stage (June 19, 21, July 2). The abdominal tergites of the nymph are not always as immaculately brown as indicated by Clemens ; there are frequently traces of pale dashes laterally and subdorsally along the anterior margins of the segments, serving to a certain extent to define the usual median and submedian dark bands and submedian dots.
