the common scurfy scale of the apple. Both of these pests are 

 noticed elsewhere in this report in some detail. 



Forest pests. The hickory bark beetle still continues as an 

 important pest in the vicinity of New York City, and here and there 

 in the Hudson valley, though the resultant damage does not appear 

 to be so extensive and severe as in earlier years. It is to be expected 

 that natural enemies will soon begin to regain the ascendency, 

 which already seems to be the case to a limited extent. It is undoubt- 

 edly true that conditions have also been materially benefited by the 

 somewhat general cutting and burning of badly infested trees. 



The establishment of the recently introduced bayonet or posthorn 

 pine borer, Evetria buoliana SchifL, in several New York 

 localities adds another potentially important enemy to our list of 

 pine pests. This European species has evidently been established 

 in the country for several years, probably being brought here with 

 nursery stock. The infestation is so limited that there is a possi- 

 bility of exterminating the borer. A detailed account of this insect 

 is given on subsequent pages. 



The maple and oak pruner, a rather common enemy of oaks, in 

 particular, has been unusually abundant and injurious, especially in 

 the lower Hudson valley and, as a consequence, many inquiries have 

 been received concerning this insect and methods of control. A 

 brief practical account of this borer is given elsewhere. 



The large European hornet, Vespa crabro Linn. , became estab- 

 lished in this country several years ago, and during the last year or 

 two has attracted notice by its habit of removing the bark from 

 small, living twigs or branches, birch suffering, in particular. Ordi- 

 narily this damage does not amount to much though it might be 

 considered serious in the case of specimen trees or shrubs on lawns. 

 A brief account of this insect is given in this report. 



Garden or greenhouse pests. The large, brilliantly colored Say's 

 blister beetle, Pomphopoea sayi Lee, has again attracted 

 notice because of its unusual abundance in various localities in the 

 State. The depredations of the past season were noteworthy, in 

 that this insect was reported as having threatened with destruction 

 the yield from an acre of beans. 



Another unusual outbreak was that of the Juniper plant bug, 

 Chlorochroa uhleri Stal., a stout, greenish, pink-margined 

 stink bug which became excessively abundant and injurious at Quaker 

 Street, Schenectady county. These bugs, ordinarily rare, were so nu- 

 merous as to destroy many of the young peas while still in the pod 

 and seriously affect the yield of several garden crops. Living speci-
