apparenth' the preferred food in Kansas. The larvae were not observed 

 feeding in nature. In captivity the}' were reared on bran and wheat 

 kernels, and there is evidently no difference between the feeding 

 habits of this beetle and the more common species of Lachnostenia . 

 The beetles occur from May to July, oviposition taking place in 

 June and July. The eggs hatch in from 10 to 14 days. The larvae 

 hibernate in the soil and reach the pupal stage in about 328 days. 

 Complete development from egg to adult requires about 352 days. 

 An Asilidfly, Proctacanthus brevipennis, has been recorded as prcdaceous 

 on Stri"oderma.

The Swiss canton of Argovie has been known to be infested since 

 1905 by Phylloxera, and many of the vineyards have been destroyed. 

 Since 1920 a determined effort has been made to resume vine growing 

 with grafted vines, and up to the present the results are said to be 

 satisfactory.

Attention is drawn to Verhoeff's observation that the larvae of 

 Chrysopa vulgaris, which occur chiefly on Tanacetum vidgare, are 

 natural enemies of Eriosoma lanigerum, so that this plant is worth 

 cultivating in gardens.

Two new species of Phloeophthorus do considerable injury in the 

 Karst region of Herzegovina to Cytisiis weldenii, which is a plant of 

 some economic value, as goats feed on the green leaves in summer 

 and on the twigs in winter. The leaves are also used as a substitute 

 for tobacco.

In view of the increase in the price of methylated spirit during the war 

 a formula recommended for its dilution, which is equally efficacious 

 in the control of woolly aphis [Eriosoma lanigerum], is five parts 

 of methylated spirit at 90 per cent., two of a 10 per cent, solution 

 of commercial carbonate of soda and five of water. A still cheaper 

 solution may be made by dissolving 9 lb. white soap in 50 gals, 

 water and adding to this 9 gals, methylated spirit at 90 per cent. 

 Owing to the low cost of this mixture, it may be applied with a sprayer 

 instead of a brush.
