10 that of his list of forty-one cynipideous oak-galls known as British, he has found all but six in Essex. In 1868 only four- teen species were known as British, so that twenty-seven species have been added in twelve years—a fact which surely offers encouragement to our workers to pursue further investi- gations in this direction. The absence of sandy banks will account for our poverty in fossorial Hymenoptera. Of other orders of insects, Mr. Doubleday has published a list of thirty species of dragon-flies (Odonata) as being known to occur in our Forest, this number being about two-thirds of the British species. To the botanist our district offers a fine field—Epping Forest is indeed regarded as being among the richest localities for plants in the vicinity of London; but I should be over- stepping the bounds of all reasonable time did I attempt to specify any of the rare flowering plants, ferns, fungi, mosses, and lichens that nature has so lavishly spread through the county. At present the standard work of reference for our botanist is Gibson's "Flora of Essex," published in 1862, and there is an older and now extremely rare book by Richard Warner entitled "Plantae Woodfordiensis," published so far back as 1771.* The outdoor study of the natural history of the county will of course be conducted as heretofore by our members indepen- dently, each according to his particular subject, but the for- mation of this Club will, I venture to think, add greatly to the zest of their pursuits. The pleasure of adding some new or rare species to the Essex fauna or flora, or of making some new and interesting observation, will assuredly be greatly enhanced by knowing that at the next meeting of the Club the captor or observer will have an opportunity of making known his results to those of kindred tastes, and an additional impulse will thus be given to his work. Such observations as our members may bring forward, or such specimens as may be exhibited at our meetings, will be gladly welcomed by the Council, and will be recorded in our publications. To many, and especially to our younger members, the new Club may perhaps be a means of inducement for taking up the * See Appendix.
