in water lived for twelve days. These experiments with syrup were 

 prompted by an observation of an adult Chalcid apparently sucking 

 the secretion from the pores of E. lanigermn. Various other points 

 of interest are being studied and will be reported on.

A new pest of the walnut in Uruguay is Eriophyes {Phytoptus) vitis, 

 on the lower surface of the leaves. This mite may be combated by 

 spraying with a 1 per cent, solution of calcium or potassium poly- 

 sulphide. Another enemy, which infests the nuts, is the well-known 

 apple pest [Cydia pomoneila].

Much damage is done by Julus sp. to potato tubers, bulbs in general, 

 and 3^oimg leguminous, cucurbitaceous and solanaceous plants. Cereals 

 and fruits are also attacked by this millipede. Traps of melon rinds, 

 lettuce leaves, etc., appear to be the only means at present used against 

 this pest. When preparing ground for vegetables, etc., carbon bisul- 

 phide should be injected at the rate of 4-10 cc. per square metre. 

 A preliminary watering with soapy water drives the millipedes away, 

 but in this case the surface of the soil must be scraped off before 

 planting. Vegetable ashes should be placed at the bottom of each 

 furrow. Against Tetranychus a 3 per cent, solution of soap or a 

 solution of tobacco extract will give good results.

From 9th March to 14th May 1921 the Defensa Agricola supplied 

 46 enquirers with colonies of Eriosoma lanigerum, Hausm., parasitised 

 by Aphelinus mali. Every indication points to a satisfactory estab- 

 lishment of this parasite.
