The San Jose Scale. (Albany Evening Journal, for November 7, 

 1894, p. 6, c. 5 — 20 cm.) 



The San Jose Scale, Aspidiotus perniciosus, is found in a pear orchard at 

 Kinderhook, N. Y., where it had been introduced in nursery stock pur- 

 chased in New Jersey two years ago. As soon as it was detected, the trees 

 were taken up and burned, and it was hoped that it had been exterminated, 

 but, unfortunately, other trees from the same source, received previously, 

 were also infested. It is now found in abundance on these: they will also 

 at once be taken up and burned. 



This scale — seen in San Jose twenty years ago, — has also been introduced 

 into Maryland and Virginia, and exists at least in one other locality in New 

 York, viz., in nurseries on Long Island. Its successive broods, and fruit- 

 trees on which it occurs, are stated . 



" North Dakota's New Bug." (Country Gentleman, for Novem- 

 ber 22, 1894, lix, p. 811, c. 2, 3 — 32 cm.) 



An insect, the appearance and habits of which are given in the Minne- 

 apolis Journal by a correspondent from Jamestown, North Dakota, is un- 

 doubtedly the box-elder plant-bug, Leptocoris trivittatus (Say) — the same 

 as noticed in the Country Gentleman of September 29th. It has never 

 before been recorded as appearing in such number. The object of these 

 gatherings can not be accounted for. Its distribution throughout the western 

 part of the United States is stated. That it has not extended eastward of 

 the Mississippi River is strange, since its favorite food-plant on which it 

 breeds, Neyundo aceroides, is widely distributed throughout the eastern 

 half of the United States. Reference is made to other notices of the insect.

Experiment Station Work on Long Island. (American Agricul- 

 turist, for December 1, 1894, liv, p. 404, c. 1 — 3 cm.) 



Letter in relation to the value of the work being done on Long Island 

 through the Geneva Agricultural Experiment Station, as shown in the dis- 

 covery of the San Jose scale in nurseries on the Island: the great importance 

 of arresting its spread and accomplishing its extermination in its eastern 

 occurrence.
