marks on the front wings, and in some specimens a red 

 coloration appears. Ormerod and Whitehead are the only 

 observers who have recorded it. At present it does not appear 

 to be at all abundant, and in the last six years I have only 

 been able to obtain a single specimen. There seems some 

 evidence to show that the Jumpers in the immature stage 

 pass the winter in crevices in hop poles, &c, for Ormerod 

 clearly shows a case of infestation in Hampshire due to poles 

 coming from a previously infested garden. 



The small Jumpers are first seen on the lower leaves of 

 the hops. No washes will kill adult Jumpers, but the young 

 larvae are said to be destroyed with paraffin emulsion. 

 Paraffin in any form on hops is liable to do a good deal of 

 harm, and should certainly never be used unless under very 

 exceptional circumstances, and then with great care. Nicotine 

 wash is fatal to this insect and its allies — even the Cuckoo 

 Spit — in the immature stages, and would be the best wash 

 to use. The adult Jumpers are best collected mechanically 

 by "jarring" them off on to tarred boards held on each side 

 of the hills.

AGRICULTURAL RETURNS OF 1909. 

 The preliminary statement of the acreage and live-stock 

 returns issued by the Board on the 20th September shows 

 that the total acreage under crops and grass in Great Britain 

 amounted to 32,183,073 acres in 1909, this representing a 

 decline of 28,313 acres from the area so returned in 1908. 

 The changes in the extent of arable and pasture land, respec- 

 tively, and in the chief categories of crops, may be summar- 

 ised as follows : —
