1913 ENTOMOLOGICAL SOCIETY. 17 



During the past summer the insect appeared in much greater numbers in the same 

 district. During the second week in July the moths were very numerous in the 

 woods, and there was much variation in their appearance, the colour of the wings 

 ranging from almost a pure, shining white to yellow, more or less spotted and 

 streaked with brown or reddish-brown. 



Garden and Greenhouse Insects. 



Garden plants were not injured by insects very seriously during the past 

 season. The Tarnished Plant Bug {Lygus pratensis) was present in fair numbers 

 and was complained of in the latter half of the season as doing some injury to 

 the buds of dahlias. In the early part of the season the Colorado Potato Beetle 

 (Leptinotarsa decemlineata) attacked freely plants of the genus Nicotiana, and 

 American Rose Slug (Endelomyia rosae) did conspicuous damage in some rose 

 gardens. The larvaB of the Bordered Sallow {Pyrrhia umbra) were present in

numbers in the rose garden at the Central Experimental Farm. In the middle of 

 July they were found attacking rosebuds, the caterpillars at that time being in 

 different stages from young larvae to larvae about one-third grown. It was in- 

 teresting to note the small numbers of plant lice which were present this year on 

 flowering plants in the beds at the Experimental FaTm. 



In greenhouses the insect which is doing most damage at the present time is 

 the Greenhouse Leaf-tyer (Phlyctaenia ferrugalis) . This has done a good deal of 

 injury in one large house, the chief damage being to chrysanthemums. The Varie- 

 gated Cutworm (Peridroma saucia) is occasionally destructive in greenhouses. At 

 the present time the caterpillar is attacking carnations in one house, climbing up 

 the plants and eating out the contents of the buds.

The season of 1912 has been rather a disappointing one to the Entomologist. 

 Not only did the cool weather, in the case of several species, ■ prevent a large 

 number of insects from reaching maturity, but the excessive rainfall gave to the 

 observation and collection of specimens somewhat the character of an aquatic 

 pastime. 



Some insects, however, seem to have prospered unusually well either on account
