 emergence of the yomit;. llie same remedy may also 1)e used for scurfy scale. 



The San Jose and. other injurious scale insects of Tennessee with methods 

 for their control, G. M. Bentley {Tennessee Sta. Bui, 1 >>/. XIX. Xo. 2. pp. 

 ll-S-'i, figx. 23). — A ])opular review is given of the history, introduction, distrihu- 

 tion, hahits, and life history of the San Jose scale with notes on its food plants 

 and the extent of its injuries. Boiled lime-sulphur wash is recommended as 

 the best remedy for this pest from a standpoint of both cheapness and efhciency. 

 Brief directions are given for preparing and applying remedies for the San 

 Jose scale, and short notes on the oyster-shell scale, scurfy scale, cottony-maple 

 scale, rose scale, and apricot scale. 



Capnodis tenebrionis, a fruit pest, LATii;RE and Guknaux {Bnl.. aS'oc. Nat. 

 Agr. France, 67 (lixn), Xo. 3, pp. 26S-271). — This insect attacks the trunks of 

 the peach and cherry trees. It is ditficult, if not impossible, to prevent the 

 deposition of the eggs on the bark by the use of sticky substances. It is sug- 

 gested that the larviB in the trunks be destroyed by the use of wires inserted 

 into the tunnels. 



Description of a new genus and species of scale insect on the olive, A. 

 Berlese and F. Silvestki {Redid, 3 (190.')), Xo. 2, pp. 39G-Ji07, figs. IS). — 

 Euphilippia olivina is described as new and notes are given on its life history. 

 This scale insect lives upon the olive and has been found in large numbers in 

 several localities. It appears that there is but one brood annually and that the 

 eggs are laid in the month of May. 



A probably effective method of destroying Ceratitis capitata and Rhago- 

 letis cerasi, A. Berlese (Redia, 3 (1905), Xo. 2, pp. 386-388) .—The gratifying 

 success had by the author in combating the olive fly by a mixture containing 

 honey, molasses, glycerin, and an arsenical leads him to believe that the same 

 method may be used effectively against fruit flies. 



The locust borer and methods for its control, A. D. Hopkins (V. 8. Dept. 

 Agr., Bur. Ent. Circ. S3, pp. 8, figs. .)). — A brief statement is made regarding the 

 damage caused by this insect, the means by which its attacks may be recognized, 

 and measures for its control. It is recommended that locusts be cut for timber 

 or in thinning operations between October 1 and April 1. If it is desired to 

 destroy badly infested trees they should be cut in ^lay and June when they 

 contain the greatest number of the borers. Beneficial results have been noted 

 as a result of spraying trunks and branches of trees with kerosene emulsion. 

 Some attention has also been given to breeding a resistant race of trees. 



Pinhole injury to girdled cypress in the South Atlantic and Gulf States, 

 A. D. Hopkins (U. S. Dept. Agr., Bur. Ent. Circ. 82, pp. -',, fig. i).— Observations 

 were made on 300 cypress trees for the purpose of studying the various species 

 of insects which are connected, with injury to the wood and bark of living or 

 dead trees. The principal injury appeared to consist of pinholes in the sapwood 

 and heartwood caused by ambrosia beetles and pin borers. The most injurious 

 species is Platypus compositus. In combating these pests the author recom- 

 mends that girdling operations be carried on in October and November and that 

 worthless gum or cypress trees be left as traps in the proportion of 1 : 50-70 

 trees to be girdled. 



The spruce-gall and larch-blight diseases caused by Chermes, and sug- 

 gestions for their prevention, E. H. Burdon (.Jour. Econ. Biol., 2 (1907), Xo. 1, 

 pp. 1-13, figs. 2).— A general study was made of the life history and appearance 

 of the various developmental stages of Chermes on spruce and larch. The com- 

 plicated life history of these insects is shown in a tabular form. Many remedies 

 have been tested in preventing the ravages of spruce-gall insects, but, according
