44 Pear Rust" — Cause Unknown. (Country Gentleman, for Oc- 

 tober 25, 1S94, lix, p. 773, c. 3 — 12 cm.) 



Further examination of a rusted pear submitted to Prof. Galloway, chief 

 of the Division of Vegetable Pathology at Washington, renders it probable 

 that the peculiar appearance of the fruit is but an unusual development of 

 its natural rust — the cause of which is unknown. 



The Indian Cetonia. (Gardening, for November 1, 1894, iii, pp. 

 55, 56, c. 3, 1 — 23 cm.) 



Beetles which are thought to be killing a young pear-tree in White Plains, 

 N. Y., by piercing the bark and extracting the sap, are the Indian Cetonia, 

 Euryomia [Eiqihoria] Inda. The beetle is known to injure ripe fruits by 

 eating^ into them and to be fond of the sap of the sugar-maple. The above 

 report lends confirmation to a statement made many years ago, but ques- 

 tioned, that it gnawed the bark of young apple-trees for the sake of the sap. 



The beetle also injures corn while in the milk by burrowing beneath the 

 husks and eating the kernels. Little can be done to prevent its injuries, 

 except "hand picking." It is apparently local, and has its years of 

 abundance. 



Injurious Beetles. (Gardening, for November 1, 1894, iii, p. 56, 

 c. 1, 2 — 22 cm.) 



Of the two beetles sent from Detroit, Mich., for name, the one that occurs 

 " in clusters on the trunks of the Norway maple" is thought by the sender 

 to be destructive in the larval state by boring in the trunk of maple, beech, 

 and birch. It is Euryomia [Euphoria] Inda, of which the early history is 

 unknown. If it can be shown to be a borer of these trees, it would be an 

 interesting discovery. 



The other beetle seen " coming out of holes in the common maple " is the 

 locust-borer, Cyllene robinioz (Forster). It has no connection with the maple, 

 and probably, from their resemblance, it has been confounded by the person 

 sending it with the maple-tree borer, Glycobius [Plagionotus] speciosus (Say). 



A Maple-Tree Borer. (Gardening, for November 1, 1894, iii' 

 p. 56, c. 2 — 12 cm.) 



A pupal-case from Millville, N. J., projecting from a maple-tree, is that of 

 JEgeria acerni Clemens. In some localities in the Western States, it is very 

 destructive t) soft maples. Its egg-deposit may be prevented by white- 

 washing the trunk, or by an occasional wash of soft soap. 



The Squash-Bug. (Gardening, for November 1, 1894, iii, p. 56> 

 c. 2, 3 — 11 cm.) 



Remedies for the squash-bug, Anasa, tristis (DeGeer), is asked for, from 

 Convent Station, N. J. 



The best remedies are believed to be, placing " traps" of bark, chips, etc., 

 on the ground near the hills, and collecting the bugs that take shelter 

 beneath them ; and searching for and crushing the egg-clusters to be found 

 on_the under-side of the leaves.
