StepvRett (W. D.). The Ashes : Their Characteristics and Management. 



—U.S. Dept. Agric, Washington, D.C., Bull. no. 299, 13th 

 December 1915, 88 pp., 16 plates, 1 map, 49 tables. [Received 

 30th March 1916.] 



This paper deals with the cultivation of the ash on a commercial 

 scale. The insect pests of this tree include : — Lepidosaphes ulmi 

 (oyster-shell scale), which is the most serious pest of standing timber in 

 northern Ohio. Trees which have been recently felled are attacked 

 by a bark beetle, Hylesinus aculeatus, Platypus sp., and Xyleborus sp. 

 (ambrosia beetles), Neoclytus caprea (round-headed borer), and powder- 

 post borers, the last-named injuring the sap wood. Losses of logs and 

 timber through insects can be nearly eliminated by rapid conversion 

 of the felled tree into lumber and by proper methods of handling and 

 storing.

The citrus scale, Chrysomphalus dictyospermi var. jnnmdifera, Mask., 

 has been found on oranges near Buenos Aires, as well as on Citrus 

 limonium, Ris., Vitis vinifera, L., Laurus nobilis, L. and on some 

 ornamental plants. Although it has not been reported before, it must 

 have been introduced some time previously, as the infested area extends 

 as far as Corrientes.
