The roots of wheat were damaged by blaclcfly grubs {Bibio sp.). 

 Cockchafer larvae, MelolontJia melolontha, L. {vulgaris, F.), attacked the 

 roots of cabbage, and those of Psylliodes chrysocephala, L., burrowed in 

 the stems, the adult flea-beetles eating the leaves. Tiptila oleracea 

 L., attacked cabbage, cauhflower, lettuce, and beetroot, eating through 

 the stem at ground level and devouring the leaves after the fall of the 

 plant. 



Beans and peas were attacked by a Capsid, Lygus pabulinus, L., 

 which caused an arrested development in the buds and crumpling of 

 the leaves, and against which nicotine sprays were employed. Aphis 

 rumicis, L., also occurred on beans. 



Potatoes were injured by Lygus pabulinus, Calocoris bipunciaius, 

 ¥., and Aphrophora alni, F. The caterpillars of Gortyna flavago Schiff. 

 {ochracea, Hb.), and G. {Hydroecia) micacea, Esp., bored in the stems ; 

 Tipula oleracea attacked the stalks, and Bibio marci, L., damaged 

 tubers stored in a pit. 



Longitarsus parvulus, F., caused much damage to flax, the crop 

 having to be resown in several localities. 



In orchards, Lygus pabulinus caused serious damage to apples, 

 but was effectively dealt with by a nicotine and soap wash. Very 

 young apple fruit was also damaged by Rhynchaenus (Orchestes) 

 fagi, L. In the instance observed, the weevils had apparently come 

 from beech trees that overhung the apples. Loganberries were 

 attacked by Incurvaria {Lampronia) rubiella, Bjerk. (raspberry shoot 

 moth), and Aspis uddmanniana, L., and raspberries by the sawfly, 

 FeJiusa pumilio, Htg. Contarinia pyrivora, Riley, was observed on 

 pears. 



In gardens, the springtails, Lipura fimetaria, L., L. armata,1n\h., 

 and Orchesella villosa, Geoff., attacked a number of plants. Dressings 

 of lime and soot are useful against these soil-inhabiting Collembola. 

 Euxoa {Agrotis) segettim, Schiff., attacked plants of henbane at the 

 ground level. 



Of forest insects. Aphis abietina, Wlk., and Lachnus pini, L., were 

 abundant on spruce and pine, and caterpillars of Poecilocauipa popidi, 

 L., were observed on silver fir, though they do not normally feed on 

 conifers. Sirex gigas, L., occurred in various districts, and in some 

 cases oviposited in young pine and larch, though breeding is carried 

 on, as a rule, in decaying or dead trees. 



Rhabdophaga saliciperda, Duf. (osier-twig gall midge) injured shoots 

 of osier. It is advisable to cut off and bum galled shoots during the 

 winter, and to tar the exposed surface of affected trunks and stems 

 in February or March, so as to prevent the emergence of the midges.
