1924 ENTOMOLOGICAL SOCIETY 73 



Apple Aphis {Aphis pomi and A. sorbi) did not seem to be so numerous as 

 last year or to cause as much damage. 



Pistol and Cigar Case-Bearers (Coleophora malivorella and C. fletcherella) 

 were so abundant around the city of Valleyfield as to almost completely defoliate 

 the trees and ruin the apple crop in many orchards. Lack of regular and thor- 

 ough spraying explains this local outbreak. Elsewhere, a few reports have been 

 made concerning the same pest, but damages were not so important. 



Bud Moth (Tmetocera ocellana) showed in about the same numbers as last 

 year. No special case of heavy infestation were reported. 



Apple Tent Caterpillar (M. americana). Important damage in June. 



Fruit Tree Leaf-rollfr {Caccscia ar gyros pila) was widely spread and was 

 certainly more abundant than the previous season (June 5-20). 



Apple Borer {Saperda Candida). More numerous than usual in some 

 nurseries. One orchard around Quebec city was cut down on account of that 

 pest. 



Shade-Tree Insects 



Tent Caterpillars (Malacosoma americana and M. disstria). Important 

 outbreak of these pests for the second successive year: showed large increase 

 over 1922. Distribution general along the St. Lawrence river. The Apple Tent 

 Caterpillar was chiefly injurious to poplars, maples, apple and cherry trees. The 

 Forest Tent Caterpillar defoliated poplars and maples and seemed more abundant 

 than the other species. First hatching at Quebec, May 17th. 



Spiny Elm Caterpillar (Euvanessa antiopa) . Found more numerous than 

 usual, between June 20-July 20, on elms and poplars. First adults seen May 

 7th; first eggs, May 8th. 



White Tussock Moth Caterpillar (Hemerocampa leucostigma) . A 

 decrease over the two last years (Quebec, July 15-August 10). 



Adults of Eulype hastata were found in the woods, on the north shore of the 

 St. Lawrence, in tremendous numbers from July 1st to 20th. In Charlevoix 

 county horses were scared to enter the bush ; specimens seen in Quebec at night 

 in large numbers. 



Fall Webworm (Hyphantria textor). Seen in good numbers during Sep- 

 tember. Not important on shade trees. Mostly confined to wild-cherry trees 

 along roads. 



Miscellaneous Insects 



Important Currant Worm (Pteronus ribesii). Last part of June, in about 

 the usual number. 



Currant Aphis (Myzus ribis). Widely spread and in large numbers. 



Three-lined Beetle (Lema trilineata). Locally observed on various vege- 

 table and ornamental plants. 



Tortoise Beetles {Coptocycla bicolor and C.signifera) damaging convolvulus, 

 eating holes in the leaves. Two cases reported.
