Say and Neurocolpus nubilus Say. Four out of the bIx belonged to the latter. This spring I thought that even though neither Mr. Baker or I had time to devote to a careful study of the life history of these insects, it might be possible by occasional trips to make some interesting and perhaps valuable observations on their habits and work. Accordingly on June 12th, when the calyces of the apples had just closed, Mr. Baker and I visited the orchard and found a good many of the nymphs feeding as in previous years on the fruit and tender part of the twigs. To our surprise many red nymphs were also seen, especially on the shoots that grew up from the crown of the trees. Xone of these red nymphs, however,.

Photo taken June 25th. were seen on or close to the fruit; but that this species (Lygidea mendax) as well as Eeterocordylus malinus does feed on young fruit in addition to the leaves, has been shown by Crosby. On June 25th, we again made a hurried trip to the or-chard. The fruit at this time averaged about half an inch in diameter and the nymphs had almost entirely ceased to feed on it, though tw^o or three were doing so. They evidently now much preferred the tips of the shoots around the base of the tree. The red nymphs here were about as numerous as the other species, but owing to their brilliant color were more easily seen. Forty or more nymphs were taken to Guelph, and twenty-two adults reared from them. All the red nymphs- four in number—proved to be Lygidea menda
