1. ~WICKLOW AND WEXFORD.~--Here we are on the East Coast, looking across St. George's Channel towards the shores of Wales. The lovely county of Wicklow is the most mountainous in Ireland, having 180 square miles over 1,000 feet elevation, and 25 square miles over 2,000. Wexford is lower and more fertile. The coasts of both counties are in great measure flat and sandy, and are the home of many rare plants. A number of species of light soils and of gravelly shores have here their Irish headquarters, such as the Round-headed Trefoil (_Trifolium glomeratum_) the Sea-Stock (_Matthiola sinuata_), the rare Sea-Cudweed (_Diotis candidissima_), and the Wild Asparagus (_A. officinalis_). The Murrough, a great gravel beach backed by salt marshes which extends from Greystones to Wicklow, and the marshes of the River Slaney, may be specially recommended to the naturalist. These coasts are the only Irish locality for the handsome ground-beetle, _Nebria complanata_, a typical South European animal. The Wicklow mountains, which reach in Lugnaquilla a height of 3,039 feet, are the main portion of the Leinster highlands, formed by a great mass of granite which stretches from Dublin into county Kilkenny. Considering their elevation this range is singularly devoid of alpine plants and animals, but many interesting species inhabit the lower grounds, famous on account of the beauty of the scenery. Among the Lepidoptera several rare species are characteristic of the district, such as the "Bath White" butterfly (_Pontia daplidice_), and the "Four-spotted Footman" moth (_OEnistis quadra_). 2. ~WATERFORD AND EAST CORK.~--This is a picturesque district, formed largely of slates and sandstones of Old Red Sandstone age. The coast is mostly of very bold character, with towering cliff ranges. The country is generally undulating and fertile, with occasional mountain ranges, of which the Comeraghs are rendered especially interesting and picturesque by the deep "cooms," embosoming tarns, which give them their name. The Comeraghs and the lovely valley of the Blackwater furnish particularly attractive ground for the naturalist. The flora and fauna of this area are intermediate in character between that of the district last considered and of the surpassingly interesting country that lies to the westward, and which will next claim attention. Thus, the coasts yield several of the rare plants mentioned in the last paragraph--for instance, _Diotis_ and _Asparagus_ grow at Tramore; while at the same time we first meet in this area with some of the most famous plants of the south-west--London Pride (_Saxifraga umbrosa_), Kidney-leaved Saxifrage (_S. Geum_), Great Butterwort (_Pinguicula grandiflora_), Irish Spurge (_Euphorbia hiberna_). Two rare butterflies of this district are _Dianthaecia caesia_ and _D. luteago_ var. _Barrettii_; and the largest of the British leaf-beetles, _Timarcha laevigata_, has been taken near Waterford, and at Tipperary.
