 Ent. Soc. Rpt. 1S93, pp. 76-84). — General discussion of the value to man of the }iara- 

 sitic and predaceous insect enemies of such species as injure vegetation, with special 

 remarks on some of the more imj)ortant injurious insects and their enemies. Insects 

 preying upon scale insects are especially mentioned and the Capri fig insect {Blast-

 ness. Parasitism in insects is briefly treated of, and a careful study of entomological 

 publications urged. 



Injurious insects of the year, J. Fletcher {Ontario Ent. Soc. Ept. 1893, pp. S-13,

 scale as an example of an injurious insect spread by nursery stock, and urging that

 introduction of insects and plant diseases that have proved injurious elsewhere.

 of the entomological work during the j^ear, specimen cases and rearing cages being
