Entomological Society of Ontario; Insect pests; Insects -- Ontario Periodicals. 51 much like the curculio does, and remain for a short time motionless ; their structure, how- ever, is not such as will permit of their disguising themselves as thoroughly as the " little turk " Joes, and hence they are easily detected. During the past season these flies were very numerous during the early part of June, and their progeny was destructive in a correspond- ing degree later in the summer. After pairing the female places her eggs singly within little semicircular incisions through the skin of the leaf, which is frequently followed by some discolouration at the point of inser- tion. Harris says that the eggs are generally placed on the lower side of the leaves, whereas in our experience we have found them quite as often on the upper side. According to the same author the flies all finish this business of egg depositing and disappear within the space of three weeks. " The flies have not the timidity of many other insects, and are not easily dis- turbed while laying their eggs. On the fourteenth day afterwards the eggs begin to hatch, and the young slug worms (see those on leaf in Fig. 41) continue to come forth from the fifth of June to the 20th of July, according as the flies have appeared early or late in the ; Fig- ^1- " At first the slugs are white; but a slimy """^ matter soon oozes out of their skin, and covers their backs with an olive-coloured sticky coat. They have twenty very short legs, or a pair under each segment of the budy excepting the fourth and the last. When fully grown (See n Fig. 41) they are _ about nine-twentieths of an inch in length. The head which is of a dark chestnut colour is small,and is entirely concealed under the fore part of the body. They are largest before, and taper behiud, and in form somewhat resemble minute tadpciles. They have the faculty of swelling out the fore part of th
