Still another Cecidonryiid, of which I did not obtain the fly, attacked 

 the foliage of the sugar maples in Kirkwood, curling and producing a 

 gall-like thickening of the edges of the leaves. The affected portions 

 turned crimson and gave the foliage the appearance of being covered 

 with long, slender, red worms. 



My attention was not called to this insect until it was too late to learn 

 its natural history or to attempt the use of any remedy. 



SCARCITY OF PARASITES OF CODLING MOTH AND PLUM CURCULIO. 



Having always had some misgivings that in the practice of spraying 

 fruit trees with the arsenites, we were destroying our most valuable 

 allies in our warfare with the above-named pests, I made it a point dur- 

 ing the past season to ascertain what proportion of them were really 

 parasited. 



Infested fruit was collected from an unsprayed orchard at intervals 

 throughout the season, and both Codling Moth and Curculio bred in 

 considerable numbers with a result 4hat 4 per cent of Curculios were 

 parasited, and from about one hundred Codling Moth larvae not a single 

 fly appeared. As the deftige-like rains of the spring and early summer 

 may have had something to do with this unexpected result, I propose 

 to repeat it another year, and hope to make a more satisfactory report.
