(whitefly). The under surface of the leaves, infested with a quantity 

 of eggs, nymphs and a few emerging and complete imagines, was 

 covered with mycehal tufts of Cladosporium and wefts of Cephalo- 

 sporium. The mode of occurrence on the Aleurodes nymph of this 

 CephaJosporium, which has been named C. lefroyi, agrees in every 

 respect with Parkin's description and figure of C. lecanii on Lecanium.

Pachypappa reaumuri was found on a broad-leafed Ume tree at 

 Bearsted, Kent, in June 1914. The tops of the shoots with the smaller 

 leaves were in most cases rolled up inside one of the larger leaves and 

 the stems were markedly bent over just below the gall. Later the 

 whole leaf mass died, owing to the constant sucking of the insects 

 within. The viviparous females kept under observation dropped their 

 young on the soil. While still small, these crawled into the ground 

 and were afterwards found attached to the roots of grass and primroses 

 growing in the breeding cage. This aphid leaves the lime in June, 

 and, according to Del Guercio's observations in Florence, returns to 

 it in September. At Bearsted, the species was attended by ants {Lasius 

 fuliginosus). A description of each of the stages is given.

Cneorrhinus {Philopedon) plagialus, Schall., has been recorded on ^ 



broom, marram-grass and vine. Everts, referring to it as a Dutch 

 species, states that the larvae and pupae have been found at the base 

 of sand-dune grasses and on firs. In the latter case, young trees are 

 chiefly attacked, the beetles feeding on the needles, cones and terminal 

 shoots. Feeding takes place during early morning and evening, while 

 during the day the insects usually hide in the ground.

 Chronicle, London, Ivii, no. 1481, loth May 1915, p. 266. 



In treating vines for mealy b\ig [Pseudococcus), all loose bark is 

 first removed from the bases of spurs around the eyes. The glass and 

 woodwork of the vinery is disinfected with paraffin solution and hot 

 lime. Loose soil from the vine borders should be removed and replaced 

 by fresh loam. The previous season's wood of the vine is then painted 

 with a mixture of clay (1 part), water (3 parts) and gas tar (1 part), 

 the mixture having been previously boiled for a few minutes and 

 allowed to cool. The eyes should be carefully avoided during the 

 operation.
