Ninth Report of the State Entomologist 297 



Washington county, which had appeared in large companies in the 

 month of May in localities in the neighborhood and devoured the 

 foliage of trees, showing a preference for the sugar maples. 



The elm tree beetle, Galerucella XanthomelcBnai^chv.)^ or G. luteola 

 Mull., as we may, in obedience to the law of priority be obliged to call 

 it, has not, so far as we know, reached Albany in its steady northward 

 progress. It is said to have done much damage to elms in Dutchess 

 county in June. 



One of the Chrysomelid flea-beetles, Systena frontalis (Fabr.), was 

 observed as quite destructive to the foliage of the gooseberry at the 

 Geneva Agricultural Experiment Station, earh^ in August. It is 

 believed that this is the first time it has been found to attack the 

 gooseberry. 



The Colorado potato beetle, Doryphora decemlineata (Say), although 

 twenty years have passed Nince it first entered the State of New York, 

 is still contmuing with us, — less abundantly in some y.^ars than in others, 

 but always in sufficient numbers to call for protection from its destruc- 

 tiveness hy the use of Paris green or London purple. Spraying or 

 sprinkling the vines with one of the arsenites is now quite generally 

 practiced throughout the State. During the j^ear it has been reported 

 as doing much damage in Chautauqua and Albany counties, but perhaps 

 not greater than in other counties where no mention of its injuries has 

 been male. In its progress northwardly the insect has reached Prince 

 Edward Island, in the Gulf of St. Lawrence, north latitude 46|^ degrees, 

 and has caused great damage to the potato crop the present year. 



The plum curculio, Conotrdclielas ne/aiphar (Herbst), was quite 

 harmful to plums in Orange and other of the Hudson river counties, 

 and in Monroe county about Rochesteri 



The little Curculionid beetle, Otiorhyiichus ovatus (Linn.), for some 

 unexplained reason, frequently intrudes in large numbers in dwelling- 

 houses. In August, examples for name were received from Moriches, 

 Long Island, where they were infesting a house to the extent of being 

 an anno3^ance to the household. For notice of some similar occurrences 

 see my 2d Report, page 51, 4th Report, page 14, and 6th Report, page 

 107; also 7)zsec^ Xi/6, V, page 46. The insect is known to be very 

 destructive to the plants that it attacks, but as it is strictly phytophagic, 

 no fear need be entertained of injury from its presence in houses. 



The grass crop was materially injured in some of the western coun- 

 ties of the State by an unusual number of " grasshoppers " (locusts), 

 probably Melanoplus femiir-ruhrura (De Geer), and allied species.
