ENTOMOLOGY. 907 



The growing- of decoy plants, or the extirpation of wild food plants, 

 hand picking, light-traps, encouraging natural enemies, proper legisla- 

 tion, and the ottering of bounties are recommended or discussed as 

 remedies or preventives. The introduction of insectivorous animals, 

 especially the mole, the author cautiously considers. He seems inclined 

 to favor such a course, although he does not care to take the responsi- 

 bility of recommending it. 



Fruit tree borers, A. Cra\v (California Fruit Groicer, 20 {1897)j 

 No. 1, p. 4). — A popular account is here given of the various common 

 fruit borers of California, with notes as to remedies and preventives. 

 The peach tree borer {Sanni)ia exitiosa) may be killed and removed by 

 means of a wire and the wound in the tree coated with pine tar. 

 Where tlie tree has been badly affected, judicious i^runing may restore 

 the tree to its normal condition. Carbolic acid and Dendrolene are not 

 to be recommended for use in the warm climate of California. 



The currant bush pest {^Egeria iipiiUformis), in the adult state, may 

 be driven away by the use of lime and sulphur. The larva should be 

 destroyed by grubbing out and burning the bush eggs. The flat- 

 headed apple tree borer [Chnjsobothris femorata) may be destroyed 

 by means of kerosene emulsion injected into its holes with a syringe. 



Locust destruction in Natal (A(jJ. Jour. Cape of Good Rope. 10 

 {1897), No. 3^ pp. 65, (JO). — A brief review of the report of the commis- 

 sioner of agriculture for ^atal for 1896. It was reported that the egg 

 deposit of the locust was less for this than the former year and that a 

 large percentage of eggs were destroj'ed by maggots, ants, etc. It is 

 said that however numerous the ''hoppers" may be they can be 

 destroyed in a few days by the judicious use of an arsenical mixture 

 applied on bait. The mixture recommended consists of 1 lb. of arsenic, 

 1 lb. of caustic soda, and 4 gal. of boiling water. To every ^ gal. of 

 this are added 4 gal. of hot or cold water and 10 lbs. of brown sugar. 



Report on the phylloxera in Hungary during the years 1891-'93 

 (Jelentes a Filloxeraiigy Alldsdrol Magyarorszdgban az 1891-93 iJc evek- 

 hen. Budapest, Hungary, 1895, pp. 57).— During this time it was found 

 that the phylloxera had increased so that at the end of 1S93 there 

 weje in the entire territory of Hungary 2,727 parishes infected. Work- 

 men were employed at the expense of the Government to destroy the 

 pest, and the establishment of nurseries of American vines was encour- 

 aged. A large amount of foreign stock was imported, and roots, cut- 

 tings, and buds distributed gratuitously or sold at a low price. In the 

 southern portion of the country some 40,000 acres of sand land were 

 parceled out and sold at a very reduced price to small vineyard 

 holders. Some idea of the magnitude of the insect pestilence may be 

 obtained from the fact that during the 3 years 5,370 metric quintals 

 (each 220 lbs.) of carbon bisulphid fthc entire production of this sub- 

 stance in Hungary) and over 4,900 (piintals which were imported were 

 used against the insect.
