Periodical Cicada : Section of sod with pupal gallery extension above ground. (Orig- inal.) less against the pupae. Some experiments carried on by the United States govern- ment show that newly emerged pupae may be destroyed by spraying with a 2 per cent solution of carbolic acid or a 15 per cent solution of acetic acid. Coating the trees with whitewash or spraying with a strong solution of lime- sulphur offers a possible protective means against e^^ deposition, as it has been stated that the cicadas do not like to sit on a white surface. Phenococcus "-^^^ ' P. dearnessi The immature insects hibernate under the rough bark of apple trees. Eggs are laid in early summer, the young migrat- ing to the under side of leaves. The in- sect secretes a cottony substance as shown in the illustration. The usual remedies for scale. Rabbits By H. F. Wilson The first suggestion would be to remove all brush piles and thickets and other places which offer hiding places or may serve as breeding places. Repellents Perhaps the easiest to apply and about as efficient as any repellent is the com- mon lime-sulphur spray applied to the trunks of the trees so as to drench them. The Arkansas Experiment Station rec- ommends painting the trunks of trees in the fall with white lead and linseed oil. Mixed paints should not be substituted for the above, as they may contain oils which would injure the trees. This seem- ed to give very satisfactory results and had the advantage of remaining on the trees for an entire season. The Oklahoma Station recommends the following formula which they found very satisfactory: "Water one gallon, one pound soap, t
