in smaller numbers than in the previous year. A table is given, showing 

 that the method of bringing down these weevils by means of a stream 

 of water is less effective than by striking the trunks. Sciaphobus 

 squalidus, Gyll., was noticed in the second half of April on cherry and 

 pear trees in large numbers. A great number of the injured buds 

 perished and the trees generally yielded less fruit. Shaking down is 

 the best remedy and sticky belts must be put on the trees in addition. 

 Byturus tomentosus, F., was observed at the end of May on raspberries 

 in the district of Valkov. The beetles enter the buds through a hole in 

 the side and destroy the pistils and stamens. They also injure black- 

 berries, apples, pears, plums, and cherries. They oviposit on the 

 blossoms up to the first half of July, and pupation takes place during 

 August and September in the soil, not more than from 7 to 10 inches 

 away from the host plant at a depth of 2 to 3| inches ; in a week the 

 pupae produce beetles, which winter in the soil. The beetles should 

 be shaken down from the bushes, which can be easily done by hand, 

 preferably in dull, cold weather. Spraying with barium chloride, 

 Paris green, djipsin, etc. may be useful during the blossoming season; 

 earlier sprayings would appear to be useless, as the larvae are then inside 

 the buds, and protected from the insecticide. The baskets in which 

 raspberries are collected must be lined with paper or cloth, so as to 

 prevent the escape of the larvae into the earth. The soil near the 

 canes must be broken up in autumn and in early spring and watered 

 with a solution of 3 per cent, carbolineum which will kill both larvae 

 and adults. Carbon bisulphide may be injected into the soil in 

 quantities of 5 c.c. to a depth of 3| inches ; the injector must be 

 directed away from the bushes and the injections made in 5 or 6 spots 

 at a distance of from 5 to 6 inches from the bush. Besides B. tomen- 

 tosus, raspberries in the district of Valkov are also subject to the 

 attacks of a small beetle of the family Chrysomelidae, Batophila 

 rubi, Payk., which destroys the parenchyma of the leaves. Sitones 

 lineatus was reported from one locality of the district of Charkov to 

 be injuring vetches, and has also damaged lentils and peas. As 

 remedies, spraying with 1| per cent, solution of barium chloride and 

 with Paris green (3 lb. of green, 6 lb. of lime in about 100 gallons of 

 water) are recommended. An adult beetle of Opatrum sabulosum, L., 

 was observed gnawing the foliage of peas, though only the larvae of 

 these insects have hitherto been recorded as pests. On the peas and 

 vetches damaged by S. lineatus, small numbers of Apion pomonae, F., 

 were also taken. Lophyrus pini, L., has done considerable damage 

 to young pine seedlings in some districts. Shaking the larvae into 

 pails, crushing them on the branches by hand with leather gloves, 

 and spraying with barium chloride and Paris green, are the remedies 

 suggested. Eriophyes {Phytoptus) pyri is found nearly everywhere 

 causing injury to the leaves of pear trees.

This is a popular treatise on the biology of, and the remedial

 where 12 species of the genus Anthonoynus have been recorded in all. The
