against this pest. Specimens of the bark of peach trees infested with 

 males of Phenacoccus aceris, Sign., were received, and in the peach 

 houses at Oosterhout all stages of this Coccid were fomid on 6th 

 Febiiiary ; the trees were suffering seriously. Painting the attacked 

 trees with 5 per cent, soap and. 5 per cent, spirit in water was 

 advised, and this remedy proved very satisfactory, the trees being 

 completely cleared of the Coccids.

Thus far, tobacco is the only food-plant of PhlJiorimaea ojjerculeUa 

 known in Deli. The relation between the insect and tobacco is so 

 close and the damage done by it so great, that every possible means 

 should be used to control it during the intervals betweeen the tobacco 

 seasons. In the second half of the year the females should be unable 

 to find any cultivated tobacco on which to lay their eggs ; there is 

 however a certain amount of wild or native tobacco which will serve 

 the purpose, and much of this is to be found on neglected rice-fields, 

 this being possibly the explanation of the apparent connection between 

 this pest and rice. During the tobacco season from February to June, 

 there is a great surplus of food on the neglected lands, and it is therefore 

 of prime importance to see that no wild tobacco is allowed to grow- 

 on or near the plantations, and wherever it is found growing, to uproot 

 and burn it ; burying is not sufficient. Every tobacco plantation 

 should be gone over once in every two or three weeks and thoroughly 

 searched, as the life-cycle of the moth from egg to imago requires about 

 a month. The Experiment Station asks that material may be sent 

 in for the purpose of breeding and studying parasites.

With a view to checking the several species of scales common in 

 the coconut plantations in the New Hebrides, specimens of the 

 Coccinellid, Cnjptolaemus tnonfrouzieri, have been introduced direct 

 from Australia and have already begun the destruction of these pests. 

 This Coccinellid is a native of New Caledonia, where it destroys the 

 scales attacking Araucaria.

This bulletin deals briefly with the influence of Ceratitis capitata, 

 Wied., on fruit-growing in South Italy. In November 1913, oranges 

 and mandarins began to be attacked ; the infestation increased in 

 December 1913 and diminished in January 1914. From February to 

 May, larvae were found in the oranges and mandarins both stored and
