30 II. The Macro-Lepidoptera of the District around Maldon, Essex. By Gilbert H. Raynor, M.A., Vice-President of the Cambridge Entomological Society. [Read May 20th, 1882.] The character of the country round Maldon is of a very varied description, and consequently affords a good hunting- ground to the student of Natural History. To the east lies the Blackwater, the estuary of which is bounded by low- lying alluvial marshes, at the present time mostly under grass, which is grazed by Bullocks, Sheep, and Horses. Here is an absence of all trees, except a few pollard willows along the banks of the ditches bounding the uplands from the marshes—a weary expanse of desolate lands, which tempts us, in the words of the poet, " To watch the crisping ripples on the beach, And tender curving lines of creamy spray ; To lend our hearts and spirits wholly To the influence of mild-minded melancholy." The marshes are protected from the tide by an artificial embankment of soil, commonly called a sea-wall. The vege- tation of the Salterns, the land outside the wall over which the tide flows every twelve hours, is quite peculiar; yet is it somewhat destitute of insect-life, except in autumn, when the gay masses of Aster trifolium throw a golden glory over all the land. These and the flowers of other plants indigenous to the marshes attract several common Noctua? in considerable numbers ; but collecting is far from easy, owing to the net- work of salt-water rills with which the marshes are intersected. Several Micro-Lepidoptera are attached to these Saltern plants, more especially to Plantago maritima, and various species of Statice and Aster. This district, I regret to say, 1
