216 Forty-fifth Report on the State Museum. 



identical with some described by me in the Country Gentleman for 

 July 4th, 1878, and not identified at the time. 



Associated with the above are some smaller pale brown, more elon- 

 gate scales, which in their carination and transverse constrictions bear 

 resemblance to Pulvinaria innumerabilis [Rath.], while they are evi- 

 dently a species of Lecanium. A few of the eggs have hatched at 

 this date (June 4th), and the young larvae are running rapidly over the 

 scales. No cottony secretion is present, but when the scale and eggs 

 are brushed away, a white powdery substance is found beneath them. 



As, on a former occasion, I have counted 1,054 eggs beneath one of 

 these scales, the rapid rate at which the insect may multiply, is evident. 

 It will be necessary, therefore, to free the infested vine from them, or 

 they will speedily destroy it and extend to other vines. 



If the scales are confined to a portion of the vine, they could be 

 removed from it at the present time and many of the eggs destroyed 

 by crushing them with a cloth held in the hands and moved over the 

 stem with a twisting motion. The cloth might be wet with a carbolic 

 acid solution or strong soap suds; or the scales could be scraped from 

 the vine with some blunt instrument and received in a broad basin of 

 water covered with kerosene. The eggs should by no means be per- 

 mitted to survive the operation of their removal, to continue the attack 

 and destroy the vine, as they undoubtedly would if not properly 

 treated. With the eggs hatched, the empty scales, it is hardly 

 necessary to add, would be harmless. ( New England Homestead, June 

 12, 1886.) 



Apple-tree Insects of Early Spring. 



Apple-tree Aphis — Apple-tree Case-bearer — Eye-spotted Bud-moth — 

 Apple-leaf Buccidatrix — Pear-tree Psylla. 



Insect attacks upon the unfolding buds of the apple tree are either 

 unusually abundant the present season (the spring of 1891) or our fruit- 

 growers are more carefully watching for insect depredations, and 

 more eager for the knowledge of means of checking them than 

 they have been in former years. Such action is wise, for just at this 

 time orchards are exposed to attack of several insect pests, which, if 

 not promptly checked, can not as well be destroyed later, and must neces- 

 sarily prove of serious injury to the coming crop. 



Mr. D wight Stone, of Lansing, Oswego county, N. Y., has written 

 me under date of April 27th, as follows:
