50 . Rose bus, Macrodactylus subspinosus, Fabr. (Coleoptera. Melolonthid*.) 
Clustering, sometimes in multitudes, upon the young apples 
and devouring them, the latter part of June, and when these do 
not suffice it, eating the leaves also; infesting likewise roses, 
grape vines, plums and cherries :—a smallish oblong buff-yellow 
beetle, with shining yellow legs and very long black feet. Length 
0.35 to 0.40. See Transactions, 1855, p. 477.

Wasps and Hornets are frequently in the habit of feeding upon 
growing apples and other sweet fruits, gnawing small roundish 
cavities in them, and also in autumn when prepared apples are 
placed in the sun to dry numbers of the same insects are again 
attracted to them. The common hornet, Vespa maculata, Linn., 
the yellow jacket, as it is usually designated, Vespa vulgaris, 
Linn., and our common wasp, Polistes fuscala,Fab., are thechief 
species which depredate in this manner. But as these insects are 
most important on account of the injuries they are liable to inflict 
upon our persons, the description of them more appropriately 
belongs to another branch of this subject.
