Slugs on Pear Trees. (Country Gentleman, for May 19, 189^, 

 Ivii, p. 387, c. 2, 3— 20 cm.) 



An attack en pear-trees in Orange, N. J., is recognized as that of the 

 pear-tree slug, Eriocampa cerasi(Peck), which also occur on cherry, quince, 

 and plum trees. The two broods are noticed. It may be killed by powdered 

 hellebore, dry or in water, spraying with Paris green, dusting with powdered 

 lime or even with road dust unless just before molting. Are there three 

 broods in New Jersey ?

'IThe Cherry-tree Aphis on the Wild-goose Plum. ( Country 



Gentleman, for May 26, 1892, Ivii, p. 407, c. 4— IG cm.) 



Insects from Central Kentucky as quite injurious to wild-goose plum trees 

 and " observed also on theburningbush," axeMyzus cerasi (Yahr.). Although 

 for a long time thought to occur only on the cultivated cherry, it is now met 

 with occasionally on the plum. Spraying with strong whale-oil soap solution 

 would be effective if all the insects were reached by it. Kerosene emulsion 

 -would be preferable, if used before the aphids are protected by the curling 

 of the leaves. This aphis is not found on the burning bush: another black 

 species, Aphis rumicis (Linn.), was probabl}^ mistaken for it. 



The Scurfy Bark-Louse. (Country Gentleman, for June 9, 1892, 



Ivii, p. 458, c. 1 — 26 cm.) 



Scale-insects on apple twigs from High Bridge, N. J,, are Chionaspis 

 furfurus (Fitch), occuring on most of the fruit-trees, and distributed from 

 the Atlantic to the Pacific, and recently found in Europe. The specimens
