This of course was due to the fine, almost summer weather which we have had this fall in Ottawa. Among orchard insects the caterpillars of the Codling- moth were abun- dant in orchards which were not sprayed, and later in the season the con- spicuous nests of the Fall-Web worm were noticed in many orchards. This latter insect was also very bad in forests, ash, elm and other trees being much defoliated. In orchards these insects are not only destructive, but make the trees very unsightly. The remedy of cutting off the branches bearing the nests when these are small is such an easy one that I cannot understand why owners of good orchards allow this insect to work on their trees. A few colonies of the Eed-humped apple tree caterpillar (Fig. 2) and the yellow- necked apple tree caterpillar were observed, but of course these did not do much harm. Cedars everywhere were much disfigured by the small cater- pillars of Argyresthia ThujieUa, a beautiful little white moth with bronzy bars on the wings. These minute larvse feed on the tips of the shoots, caus- ing them to die and lose their natural color. I am glad to inform the members of our Society that I have been able to continue my collection of lepidoptera, most of my time being spent in work- ing up our small forms, the micros. The specimens which I have brought with me will, I think, delight some of jon. For these small moths the season has been very good at Meach's Lake, where I spent the summer, but speak- ing generally, I do not think the season was as good as 1905, at least in the Meach's Lake Please note that these images are extracted from scanned page images that may have been digitally enhanced for rea
