18 ' THE KEPOJiT OF THE No. 36 



moths were noticed in numbers at Britannia, near Ottawa, on June 37th; on June 

 29th thousands were present around the arc lights in Ottawa and flights were 

 also observed in early July. 



During the winter of 1913-1913 the eggs of this species were present in count- 

 less thousands on shade trees in the streets of Ottawa. During spring and early 

 summer it was an unusual sight to see the large numbers of these trees which had 

 been banded with ordinary tanglefoot fly paper. At the present time there are 

 plenty of eggs on the trees in Ottawa, but fortunately they are not nearly so 

 abundant as they were a year ago. 



Attacking Greenhouse and Garden Plants. 



The Bordered Sallow {Fyrrhia umbra). The caterpillars of this noctuid 

 moth, which are green, spotted with black, have the habit of eating into buds of 

 roses and other garden plants. During the past season roses particularly were 

 reported as being injured. 



Root-Infesting Aphid. Several complaints were received of an aphis attack- 

 ing the roots of asters. One complaint reached me on Aug 7th which stated that 

 whole plots of asters had been destroyed in some gardens in Ottawa. Asters on 

 the grounds of the Experimental Farm were also injured apparently by the same 

 species. 



Eed Spider. In dry seasons, such as that of 1913, the so-called red spider 

 is usually very prevalent. During the past season very serious injury was caused 

 by these mites to a large number of different kinds of garden plants, particularly 

 sweet peas. The injury was very apparent in the middle of August. 



Cutworms in Greenhouses. Occasionally we receive reports of injury by 

 cutworms in greenhouses. One of the most interesting of these which lias come 

 to my notice, occurred in the carnation house of one of our Ottawa florists. During 

 the winter when the injury was noticed I visited the greenhouse and found that 

 the species responsible for the damage was the Variegated Cutworm (Peridroma 

 saucia). Practically the only injury was to the buds which were in many instances 

 entirely eaten out during the uight by the caterpillars, as shown in the photograph 

 reproduced herewith (Fig. 'i). Cutworms in greenhouses can easily be controlled 

 by scattering poisoned bran wherever they occur. 



Division No. 3, Toronto District — A, Cosens. 



The season of 1913 should go on record as a very favourable one for collecting. 

 Long spells of fine weather, broken only for short intervals by occasional showers 

 have characterized the summer. The autumn has been exceptionally warm, and 

 insect activity has been correspondingly prolonged. A Mourning Cloak butterfly 

 (Vanessa antiopa, L.) had sufficient energy to flutter about in the enjoyment of the 

 warm sunshine of November 3'rd, and numerous Crane Flies (Trickocera macu- 

 Upennis, Fabr.) were still zig-zagging in the smoky air on November 13th. 



The Tussock Moth was much more plentiful in Parkdale this season than it 

 has been any previous one. The cocoons were formed even in crevices of the 

 foundations of houses and under stone window sills; besides such unlikely places 

 they were plentiful along the fences, and in some trees they were literally massed 

 at the axils of the branches. If this species were not extensively parasitized the
