At Highmoor Farm this species was found quite abundant and con- siderable injury to oats could be credited to it. The leaves showed much evidence of punctures often associated, probably followed by, attacks of rust or fungous disease. In many instances as had been observed by Dr. Surface, pimctures at the base of the glumes passing through to the kernel were evidently responsible for injury to the grain. It occurred also on many other plants, commonly on grasses, timothy especially; buf a more unusual occurrence was noticed on potatoes and corn. This occurred probably only on the ripening of the adjacent oats and migration of the hoppers as no larvae were observed on either of these crops. The occurrence on corn is especially interesting as it is, I think, not only the first occurrence for this species' but the first time I have encountered any of the jassids living on this crop. In no case was the insect present in excessive numbers and still the injury to oats was sufficient to deserve attention. The results of a study of the life history of this species in 1914 will appear in a forthcoming Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustratio
