cod lino: moth may pass the winter in storage houses it is recommended that such 

 buildings he fumigated al the rate of 3 lbs. sulphur per 1,000 cu. ft. of space. In 

 addition to insect parasites of the codling moth a fungus disease was observed due 

 tn Isaria farinosa. 



Spray solutions for San Jose' scale, T. B. Symons i Maryland si,,. Bui. 99, pp. 

 85-96,.figs. .'). — During the past season tests were made of lime-sulphur-salt wash, 

 caustic-soda and potash solutions, and various proprietary insecticides. Experiments 

 were also carried out to determine the relative value of fall, winter, spring, and 

 summer applications. 



The various combinations of lime, sulphur, and salt gave satisfactory result-. 

 Boiled solutions were apparently more effective than unboiled. Lime and sulphur 

 wash without salt gave good results in some cases. The addition of caustic soda or 

 potash to the solution seemed to yield a slight advantage. None of the proprietary 

 insecticides, which included San Jose exterminator, consol, webcide, and kill-o-scale, 

 was of any value. 



Experiments in spraying trees, December II to 15, showed that the lime-sulphur- 

 salt wash may be successfully used at this season. Spring applications also gave 

 good results, and, on the whole, this seemed to be the most favorable time for 

 spraying. As a result of the author's experiments the only insecticide generally 

 recommended for the control of San Jose scale is the lime-sulphur-salt wash made in 

 the proportion of 20 lbs. lime, 15 lbs. sulphur, and 10 lbs. salt per 50 gal. of water, 

 and applied in the early spring. 



Practical treatment of the San Jose scale, S. A. Forbes i Illinois Sin. < \rc. 85, 

 l>l>. 4). — The experimental work done at the station during the past 4 years has 

 demonstrated that the San Jose scale may be controlled, or in some instances exter- 

 minated, by the use of lime and sulphur sprays. 



The greater part of the State is free from San Jose scale, but it is impossible to 

 prevent it from becoming more widely distributed. The lime and sulphur washes 

 should not be applied while trees are in leaf. The best time for their application is 

 in the late winter or early spring. It is also recommended that all infested Osage 

 orange hedges be destroyed since the San Jose scale breeds in these hedges, and it is 

 difficult to treat them thoroughly. Detailed suggestions are made regarding the 

 preparation of the Oregon wash and the California wash. 



Oscinis frit, A. Carlier {Ann. Gembloux, 15 {1905), No. l,pp. 19-24). — The author 

 describes the great injury which this insect does to oats. The pest is described in 

 its different stages and notes are given on its life history. In combating this pest the 

 author recommends that a suitable system of rotation be adopted in order to prevent 

 the multiplication of the insect. 



A new parasite of the eggs of Phlyctaenodes sticticalis, K. E. Demokidov 

 {Rush. R,,t. Obozr.,4 {1904), No. 5, pp. 207-209). — Xotes are given on a hymenopterous 

 parasite which lives in the eggs of this insect, and a brief account is also presented 

 of the parasites of the Hessian fly ami brown-tail moth. 



Tabanidae of the western United States and Canada, J. S. Hine ( Ohio State 

 r,nr. BuL, 8. ser., No. 85; reprinted from Ohio Nat., 5 {1904), /'/>■ 117-248). — The 

 purpose of this paper is to furnish aid in determining the Tabanidae of that part of 

 the country which is not well covered by Osten Sacken's work on the diptera. A 

 key is furnished for the identification of the genera and species and a list is given 

 showing the species treated with synonymy and bibliographical references. 



Biological notes on species of Liodes, A. Fleischer ( Wiener Eat. Zlg., 23 {1904), 

 No. 9, J,/'. Wl-254)- — Brief notes on the habits and life history of the various species 

 of the Liodes genus. 



The palearctic forms of the dipterous genus Lispa, T. Becker {Ztschr. Ent., 

 n. ser., No. 29, pp. 1-70). — Descriptive notes are given on a large number of old and 

 new species of the genus Lispa.
