years. The flowers are dried in the shade and ground up, the powder 

 acquiring its full virtue after slight fermentation for three months. 

 It must be stored in air-tight containers. Adulteration with camomile 

 or artemisia is sometimes practised. Closed pyrethrum flowers fetch 

 about £6-£7 per cwt. on the Italian market at present.

Flower-bulbs growing in the open at Lisse were injured by the 

 Sylvanus Cucujid {OryzaepMlus), surinamensis, L. The larvae feed on 

 dry apples, dry figs, bran, etc., and also on the buck-wheat husks used as 

 a covering for the bulb fields. The adults leave this cover and attack 

 the bulbs.

Besides the pest mentioned in the preceding paper, the buck- wheat 

 husks harbour other insects, and also Tyroglyphus farinae, L. (flour 

 mite), which seems to thrive in hyacinth bulbs. The husks should 

 therefore be exposed to a scorching heat before being spread over the 

 fields.

 Pines in the Woking Distnct. ~ Entomologists* Mthly. Mag.,

The pines felled at Woking in 1916, now contain innumerable 

 larvae, pupae, and imagines of Tomicus laricis and H ylastes palliatus in 

 their bark, but H. ater and Myelophilus piniperda, both destructive 

 at times in the district, are only just in evidence, these latter attack- 

 ing more recently felled trees. The carnivorous beetle, Pediacus 

 depressus, has appeared in some numbers among stacked pine logs.

The weevil, Prionomerus calceatus. Say, was originally described as 

 mining the leaves of Magnolia, but has been recently found destroying 

 those of Liriodendron and Sassafras, though these were never attacked 

 w^hen growing side by side with Magnolia. 



The common cow-pea weevil, wliich attacks the terminal buds of 

 cotton, was found feeding freely on the tender stems of Smilax. 

 Ambrosia, Sassafras, Liquidatnbar, Ruhus, and Melia, indicating the 

 method by which some common species that live on cultivated 

 crops pass the season preceding the development of their natural 

 food-plants. 



The flat galls of Phylloxera caryae-avellana, Riley, were found to 

 be infested by the larvae of Anthonomus hicoriae, Pierce ; several 

 other weevils of the same' group_ also breed in Phylloxera galls.
