( Ei'idplilies rihis. >(;ilepii.) The disease caused liy this mite is popuhirly called " Big ; During recent 3'ears the mite has liecome one of the worst pests with whieh the friiit-grower has to reckon, the damage done is enormous, and no nreans ot extermination has yet Ijcen found. The difficulty experienced in getting rid of the disease is due entirely to the position of the mites inside the Ijuds. Although, thanks to the work of Xewstead (f), Lewis (2), and Warbnr- ton (o), we know a great deal about the life-history, yet there are still nuiny points upon which we have not yet sufficient knowdedge. The minute mite that causes the disease belongs to a family of acari now Ixuowii as the ]'Ji-ioiihiiii'](i\ formerly as riiiiii>i>l'iihf. Other mites whicli be- long til this family are pro- tected fiy tlie bud in a similar way : the Xut find Mite {E. lici'lhinii', Anierk), the Birch Mite, E. raiUs (sub. sp. tiiii'iriis) (Can.) and the Yew Mite {E. hi,;, Murray), all of which cause the buds to swell in the same way as does E. rihis on the black curraut. Galls arc formed by many of these miles on tlie leaves of various plants aud trees, such, for instance, as the several kinds of small red galls frequently found in nuudjers on tlie leaves of the maple and sycamore, and the common " nail galls " of the lime. They are usually situated on the upper surfaces of the leaves, the aperture being fielow, and they may lie covered inside with a whitish downy substance, ilites tielonging to this lamily attack other fruit.
