An insect injurious to shrubs and shade-trees which seems to be on the increase lately is Ormcnis prnijwsa, a large stoutly-built leafhopper resembling a small bluish grey moth. I first noticed them in large numbers in 1901 on some shrubs which were planted in the spring of the same year. This year they were everywhere and showed themselves to be possessed of by no means a restricted appetite. While most abundant on the Virginia creeper and grape- vine they were common on many other shrubs and trees, etc., such as the elm, maple, bass- wood, gooseberry, almond, Tartarian honeysuckle and rhubarb. The larvis are whitish creatures not much like the adults in appearance, and have the habit of arranging themselves in irregular rows along the smaller branches and twigs, the whole aggregation being partly enveloped in a white flocculent material. The full-grown insects were first observed towards the end of July and remained until the beginning of October. Late in September they could be seen resting on the trunks of almost every shade tree except horse chestnuts, upon which they were very scarce and were probably accidental. Among the insects which were abundant last year but have not been troublesome this season the Birch Bucculatrix {BticculatrLc Canadensisella) is noteworthy. The trees have been quite healthy the whole of this year, though in May I noticed that some of them were rather badly infested with a large species of aphid. Butterflies on the whole have been scarce according to the statements of local collectors, and two of our most destructive grasshoppers Melanoplvs atlanis and Gamnula pell
