Excerpt from The Canadian Entomologist, Vol. 49 All sections of the leaf are attacked, specimens being found close to the ground or far out at the tips of the leaves. The sexes appear on the leaf very similar to the viviparous forms, with the exception of the smaller size. The genus belongs to the Callipterini, but seems to be quite distinct from the other genera in the tribe. It would appear that Theobald has been led into the error of describing the cauda as bifid by the very marked division on the last abdominal segment in the type species. In examining scirpus this is the most apparent structure on the caudal portion of the abdomen. The cauda, however, is distinctly knobbed, and the anal plate in the apterous forms appears almost as two distinct plates. This is more plainly seen in some of the other species than in scirpus.
