ArniDS. The injury from these has, on the whole, probably not been so 

 great as usual, hut there have been some exceptions. It seems that orchards and 

 nurseries situated near the great lakes and influenced by the moist, cool breezes 

 are much more severely infested than those further inland. In the control of 

 aphids 10 lbs. soluble sulphur and 4 lbs. common laundry soap to 40 gals, water, 

 applied as soon as the eggs have all or almost all hatched, promises to be the 

 cheapest remedy. This will burn if the buds have opened and the leaflets appeared. 

 Black-leaf 40 and lime-sulphur is also good but more costly. 



Apple Curculio {Anthonomns quadrigibhus). Injury to apples from this 

 insect can be found here and there all over the Province. It seems to be worst in 

 the eastern part. One orchard at Mountain, twenty-five miles from Ottawa, 

 showed in September, 50 per cent, of the Tolman Sweets deformed by punctures. 

 Doubtless many more apples had dropped off early in the season. 



Capsid (Neurocolpus nubilus). The nymphs of this Capsid were found on 

 June 16 in large mimbers in a forty-acre orchard in Norfolk County attacking

a block of Spy trees. Approximately 50 per cent, of the apples were attacked, 

 though some of them were not permanently injured. At this date the apples were 

 about two-thirds of an inch in diameter, so that they had reached the stage where 

 the nymphs were ceasing to feed on them and were attacking the tender leaves 

 and stems of shoots from main branches and of the suckers that sprang up from 

 the crown. This part of the orchard was in grass but it is not probable that 

 this accounts for the presence of the pest. In 1912 I reported a similar injury 

 from this species to Spy apples at Woodburn, not far from Grimsby. 



The nymphs are light green, interspersed with brown or reddish brown. 

 The antennae are very conspicuous. They are longer than the body, reddish 

 brown with alternating broad Avhite rings. The occurrence of numerous black 

 capitate hairs give to the second joint especially a swollen appearance. The 

 adults are about the size of the Tarnished Plant Bug {Lygus pratensis) but are 

 somewhat longer and narrower. The general dorsal colour is brown mottled 

 with black with a reddish area near the costal margin of the upper wing just in 

 front of the membrane. The antennae are longer than those of L. pratensis, and 

 have the basal segment longer, thicker, and covered with black capitate hairs.
