The hind-wings are a dusky grey, without markings. The wings expand about an inch and three quarters. We have usually taken the moth in the month of Au- gust, and have found it in various parts of this Province. As this species is seldom numerous, it is unnecessary to suggest any remedy. In aU probability its numbers are prevented from becoming excessive by some insect paiasite. 5. The Io Emperor Moth {Hyperchiria varia, Walker). Letidoptera-Saturniad^. Besides the foregoing, there are two other insects that affect the hop-vine, respectinff ?which we would say a few words before leaving this subject. One of these is so very general a feeder that it can hardly be termed a Hop insect; it is the larva of what ia commonly known as the Io Emj)eror-Moth, of Harris {Hyperchiria varia, Walker). It feeds indiscriminately upon the leaves of willow, elm, white poplar, cornel, sassafras, cherry and locust, as well as the Hop ; it is even said to eat clover and the leaves of In- dian torn. When first hatched out, tlie caterpillars are dark brown, and covered with bristles; later on. when about a third of an inch in len
