The continued dry, hot weather in 1921 in Bavaria resulted in the 

 occurrence of great numbers of the Chrysomehd, Melasoma viginti- 

 piinctata, L. In one district this normally harmless beetle not only 

 attacked its usual food-plants, Salix alba and other willows, but also 

 other foliage trees, which it almost defoliated.

Referring to a record of Sitodrepa panicea boring into those parts 

 of a leather trunk where paste had been used [R.A.E., A, x, 145], 

 a similar case is described, where the leather itself was eaten.

In a previous notice the value of birds was illustrated by the 

 immunity of a forest from severe infestation by Dasychira pndibunda 

 {R.A.E., A, X, 257]. The author, whose arrangements for bird pro- 

 tection were believed to be responsible for this result, reports that the 

 immunity has continued in the past season under conditions prov- 

 ing conclusively that birds were the chief factor in preventing the 

 defoliation seen in the surrounding forests.

An interesting account is given of the bionomics of termites in 

 general, and of Leucotermes lucifugiis, Rossi, in particular. L. liicifugus 

 is now a common and dangerous pest of constructional timber in some 

 towns of western and south-western France. In cases where the use 

 of timber is unavoidable in building, its impregnation with suitable 

 substances and proper constructional methods are important factors 

 in preventing infestation. Among the various measures against this 

 pest, fumigation is strongly advocated, and the author has obtained 

 success with chloropicrin in a house that was badly infested, by 

 spraying the liquid at the rate of 15 gm. (about \ oz.) per cubic metre 

 (about 35 cu. ft.). The rooms were kept closed for 16 hours, and this 

 time sufficed to kill the termites within the beams.
