sulphur can be used, in the absence of carbon bisulphide. The burning 

 of 500-600 grammes of sulphur for each cubic metre of space for three 

 days is sufiicient to destroy the weevils. From the point of view of 

 the ultimate destruction of the pest, the cleaning of the actually 

 infested grain by means of winnowing and fumigation, for which purpose 

 sulphur can also be used, are of less importance than the prevention 

 of the spread of the pest to uninfested grain.

This paper describes and figures sheets which have been used with 

 great success against Anthouo/mis ■ponionvm. The usual failure of 

 this method is attributable to the small size of the sheets on to which 

 the weevils are shaken. The author used two sheets for each tree, 

 each being about 4 or 5 yards long and half that width, with a piece 

 cut out at the point where the edge touches the trunk. Still bigger 

 sheets were used for old and large trees. Instead of striking the 

 trunk of the tree with a wooden hammer, Avhich is ineffective and 

 damages the bark, the branches were themselves shaken and the 

 weevils that fell were at once crushed to death. By employing this 

 method during April, it was jjossible to free the orchard from this 

 pest and no damaged buds were observed during blossoming. Before 

 shaking, it is advisable to spray the trees with water, as this prevents 

 the weevils from escaping by flying.

At Sinil)irsk large outbreaks of Hyiionomeala ifuduiellus have 

 occurred during the last two years. Spraying with Paris green or 

 \\ith the mixture of arsenic and lime recommended by Rogozin [see 

 this Review, Ser. A, iii, p. 21] proved very successful, but was not 

 universally carried out and great loss was suffered by local horti- 

 culturists in consequence.

Tyroglyphiis {AleurobiHs) farinae is primarily a pest of flour and 

 grain, but it is often found in many other food-stuffs, including all 

 kinds of dried fruits. The white inflorescence frequently present on 

 such fruits is nothing but the bodies of iimumerable mites, covered 

 Avith particles of crystallised sugar. The author gives a short account 

 of the life-history of this mite and discusses the methods of fumigatino:
