indirectly destroy the larvae and pupae of A. pomorum, by attacking 

 the buds of apples in which they are present. An internal parasite of 

 the hibernating imago was found in two cases in its larval stage, but not 

 identified ; other Ichneumonid and Chalcidid parasites were found 

 in the adult larvae, pupae and even young imago. The buds, which 

 for some reason or another dropped from the trees, were found to con- 

 tain a larger percentage of parasitised insects than those remaining 

 on them.

The orchard pests recorded in this paper include : — Choreutis 

 parialis, of which the second generation was particularly numerous ; 

 Cijdia fomonella, for the caterpillars of which belts made of felt 

 were found especially attractive ; Anthonomiis pomorum ; Psylla 

 pyricola. against which spraying in autumn with 6 per cent, copper 

 sulphate was very effective ; Recurvaria {Gelechia) nanella ; Aphis 

 pruni, against which a decoction of quassia was effective ; and 

 Lepidosaphes idmi {Coccus conchiformis). 



Cabbages were injured by PhUella maculipennis (cnwiferarum) ; the 

 best results were obtained by powdering the plants, when the dew 

 was on them, with a mixture of basic slag and Paris green in the 

 proportion of 100 to 1 ; spraying with Paris green was ineffective ; 

 the same remedy was also used with good results against Pieris brassicae, 

 the larvae of which were also collected and crushed by hand ; for the 

 control of ChortopJiila {Antliomyia) brassicae, lime was dusted round 

 the stalks near the soil so as to prevent oviposition.

This is a continuation of previous work by the same author [see this 

 Revieiv, Ser. A, ii, p. 311] and contains a report of his investigations in 

 1914. The most serious pests of cotton in the year under report were : 

 Telranychus telarius, L., Aphis gossypii, Glov., Thrips fiavus, Schr., 

 and Euxoa segetum, Schiff. The caterpillars of the last-named did 

 considerable damage to young plants ; some females were caught as 

 early as the middle of April and the first injury was noticed about a 

 fortnight afterwards ; the caterpillars were found to injure germinating
