oranges. Good results have also been obtained from the use of a mixture containing 

 5 kg. sulphate of iron and 5 kg. lime per 100 liters of water. 



May flies and midges of New York, J. G. Needham, K. J. Morton, and O. A. 

 Johannsex {X. Y. Stale Mus. Bui. 86, pp. 352, pis. 37, figs. 18).— This constitutes the 

 third report on aquatic insects based on investigations conducted under the direction 

 of the State entomologist. 



A special account is presented of the summer food of the bull frog as observed at 

 Saranac Lake. The insect and plant food of the bull frog is classified in a tabular 

 form according to its systematic position. Special notes are also given on the different 

 kinds of food found in the stomach of the frogs examined. 



The greater part of the bulletin is occupied with a biological account of Ephe:.ie- 

 ridte, Hydroptilidre, and nematocerous Diptera. The habits and life history of 

 many of the species are considered. Analytical tables are presented for the ready 

 identification of the species 'and many new species are described. A bibliography 

 relating to the subject is also given. 



Report of the entomologist, C. B. Simpson ( Transvaal Dept. Agr. Ann. Bpt. 1904, 

 pp. 345-352). — A brief account is given of the equipment of the entomological depart- 

 ment, legislation regarding injurious insects, orchard fumigation, beekeeping, locust 

 destruction, Novius cardindlis, and insects injurious to man, plants, and stored 

 products. 



The monthly bulletin of the division of zoology, H. A. Surface (Penn. Dept. 

 Agr., Mo. Bui. Dlr. Zool, 3 {1905), Xos. 2, pp. 33-64; 3, pp. 65-96; 4, pp. 97-128; 5, 

 pp. 129-160, pis. 2, figs. 5). — Brief discussions are presented of plant lice, cabbage 

 root- worm, scale insects, nursery inspection, flies, fumigation of buildings, fall web- 

 worm, preservation of birds, canker worms, Hessian fly, etc. A spraying calendar 

 is also given. 



Cooperative spraying- experiments, M. V. Slingerland [New York Cornell 

 Sta. Bui. 235, pp. 81-98, figs. 10). — A series of cooperative spraying experiments for 

 different purposes have been carried out with various fruit men with the result that 

 while no new discoveries have been thereby secured the experiments have served as 

 object lessons for neighboring fruit growers. 



In spraying for plum curculio some of the fruit men reported no beneficial results 

 on account of the fact that the curculio did not appear in large numbers. Others, 

 however, found benefit from the use of arsenate of lead at the rate of 2\ lbs. per 50 

 gal. of water. Three applications were made, just before blooming, just after the 

 petals fell, and again about a week later. The author recommends that arsenate of 

 lead should be applied at least twice at the rate of 3 or 4 lbs. in 50 gal. of water or in 

 Bordeaux mixture. The New York fruit growers appear to consider it unwise to 

 cultivate cherry orchards late enough to affect the plum curculio. One fruit grower 

 sprayed for the quince curculio at the rate of 2\ lbs. of arsenate of lead per 50 gal. 

 of water. Two applications were made and the results were favorable to the con- 

 tinued use of this method. 



Further experiments in spraying for the control of the grape root-worm indicate 

 that this pest may be satisfactorily kept in check when grapevines are sprayed with 

 arsenate of lead at the rate of 8 lbs. per 100 gal. of water. The total expense of 

 spraying is about $3.25 per acre, and an examination of grapevines showed that in 

 many cases the insects were entirely eradicated. The leaves on sprayed vines 

 remained green and healthy long after untreated vineyards began to look brown. It 

 is believed that two applications of arsenate of lead will be necessary, one as soon as 

 the beetles appear and the other about a week or 10 days later. 



A comparative test was made in the preparation of Bordeax mixture from ordinary 

 line and "new process" lime. It appears that some dealers sell air slaked lime for 

 prepared limes. It should be remembered that in order to make a satisfactory Bor-
