sought winter quarters. This is followed by suggestive rules prepared by the 

 entomologist, C. E. Sanborn, relative to burning hibernating places. 



Currant and gooseberry aphids in Maine, Edith M. Patch {Maine Sta. BuL 

 225 (1914), pp. 49-68, pis. 4, figs. 11). — Eight species of plant lice which have 

 been found feeding upon currants and gooseberries in Maine are here described, 

 three, namely. Aphis varians, A. sanborni, and Myzus dispar, being new to 

 science. It is stated that none of the eight appears to pass the whole of its 

 life cycle on currants or gooseberries. 



Part 4 of a food plant catalogue of the Aphidie of the world (E. S. R., 30, 

 p. 8r>4) is appended (pp. Gl-GS). 



Suppression of the cottony cushion scale in Louisiana, E. S. Tucker 

 (Louisiana St^s. Bui. 145 (1914), pp. 2-8, figs. 3). — The cottony cushion scale 

 (Icerya piirchasi) was first observed in Louisiana in October, 1912, on a row 

 of small orange trees adjacent to a nursery near New Orleans. The trees 

 were destroyed and the pest was thought to have been eradicated but in June 

 of the following year it was found in groves of orange, mandarin, and tan- 

 gerine trees on three private estates of about 5 acres in extent. Spraying 

 tests were made with different sprays and sprayers but insiiections made in 

 each case about two weeks after application showed a few scales to have 

 escaped. Thus it was necessary to cut and burn all trees and other infested 

 vegetation. It is thought that kerosene emulsion to which potassium cyanid has 

 been added at the rate of 1 oz. to each gallon of the stock emulsion may eradi- 

 cate the scale if applied in the early stages of infestation. A brief description 

 is given of the pest, its food plants, natural enemies, etc. There is said to be 

 no authentic record of the occurrence of this pest in Louisiana prior to 1912.

Euxoa segetum and how to combat it, A. Sopotzko (Chto Takoc Osimyi

 diseases, parasites, and methods of combating it are included.
