Abstract
In my paper on the nymph of Cinygma integrum (1933, Can. Ent. LXV, 73) there is a rather serious error which I wish to correct. At the time my material was limited to a single nymphal exuvia; now with the mature nymphs and more exuviae at my disposal I find that the peculiar nature of the maxillae, as described and figured in the above paper, was abnormal and probably brought about by contraction occurring during the process of making a slide of the mouth-parts.Keywords
