THE REPORT OF THE 



No. 36 



fausta is quite destructive to Montmorency cherries in 'New York State. Osten 

 Sacken got the specimen he named from New Hampshire, and Aldrich says in 

 his letter that he has had several reports of it in the Eastern States. The speci- 

 men he described in 1909 in Can. Ent. was from British Columbia, and I notice 

 that Mr. A. Gibson has added a note to Aldrich's article stating that this and 

 aot cingulata is probably the species that caused considerable damage to cherries 

 in British Columbia. The chances are, therefore, that it is a Avell established 

 pest that has been with us for years, but overlooked. 



The most striking differences between it and cingulata are that it is con- 

 sciderably larger — this was the first thing that caused it to attract my attention — 

 the abdomen- is black, lacking the white crossbands, and the dark crossbands on 

 the wings are very differently arranged. That it was found on the pear foliage 

 was apparently due to the pears being the outside row and the insects having a 

 better chance here to enjoy the sunlight than among the crowded cherry trees. 

 About two weeks later most of them were visible on the cherry leaves and fruit, 

 and very few on the pear. On June 22nd, the date of their discovery egg laying 

 had apparently not begun.

 Capsids Attacking Apples. 



Four years ago my attention was called by Mr. Joseph Tweedle to the large 

 number of more or less deformed fruit in his apple orchard, situated about twelve 

 or fourteen miles south-east of Hamilton. On examining the apples I suspected 

 that insects of some kind might be the cause; accordingly the next spring (1910) 

 I visited the orchard a week or so after the blossoms had fallen and succeeded 

 in discovering several Capsid nymphs feeding on the fruit and producing depres- 

 sions or scars wherever they had fed. About a dozen were collected and taken 

 to Guelph, but in my absence the adults reared from them were not looked after, 

 and moulded in the breeding cages. The nymphs were greenish in color, with 

 brownish or reddish brown wing pads, and most of them, at least, had conspicuous, 

 hairy antennae. No red nymphs were seen anywhere. In the spring of 1911, I 

 again visited the orchard and found the same type of nymphs present. One or
