Twelfth Kefort of the State Entomologist 317 



respondents, Mr. W. R. Walton, of Middletown, N. Y., has been fortu- 

 nate in his collection of it and has kindly contributed a number of exam- 

 ples to the State Collection. He also has been successful in breeding 

 from it the beautiful Lepidopterous parasite, Eiicleniensia Bassettella 

 (Clemens), with which it is so frequently infested and of which he has 

 made excellent colored drawings in its several stages (PI. V, figs. 2-7). 

 From Kermes taken from scrub oak in the latter part of December, he 

 obtained the moth toward the last of the following June. The larger 

 number of the mature Kermes were found to be infested by the parasite. 



The Elm-Tree Bark-Louse. 



Gossyparia ulmi (Geoffrey), an European Coccus, feeding on most of 

 the varieties of the European and American elms, was first noticed in 

 this country at Rye, Westchester county, N. Y., in June of 1884. (See 

 Howard in Insect Life, ii, 1889, pp. 34-41). Examples of it were 

 brought to me from Marlboro, Ulster county, in July of 1888, Since 

 that time, it appears to have become distributed in different portions of 

 the State, and to have planted itself in several localities in the vicinity of 

 Albany. In May and again in June, it was brought to me from Loudon- 

 ville, Albany county, and in June of the same year, from two places in 

 the city of Albany, and also from Catskill, Greene county, 40 miles to 

 the southward. 



In June of the present year, Mr. J. B. Washburn, brought a limb of 

 elm from his grounds at Delmar, Albany county, bearing dense patches 

 of the Coccid. It was blackened to a degree that indicated the abundant 

 presence of the insect the preceding year. The tree — a young one — of 

 about three inches diameter of trunk, was infested both upon the trunk 

 and the limbs. Other elms upon his grounds were not infested. The 

 scales were apparently about full-grown, but no young had yet been 

 given out. 



A large number of trees in the city of Albany, are at the present time 

 (in August), showing severe and injurious attack from this insect. The 

 leaves are blackened by their secretions, and some of the branches 

 whitened by their abundant presence. Their larvae, about half-grown, are 

 to be seen in large numbers in the crotches of the smaller twigs, on the 

 lower surface of the leaves, and in the crevices of the bark. The infested 

 trees are mainly the Scotch elm, Ulmus montana. 



The insect is also quite generally distributed in Troy — six miles to 

 the north of Albany, where in combination with the attack of the elm-
