Gen. OXYTELUS. O. morsitans, Grav. Staph. morsitans, Payk. Marsh. This and the following members of the genus are found in great numbers in the warm days of spring, on stones and wall tops, and perched on blades of grass, in the vicinity of stables and cow-pastures. They are so difficult to distinguish, owing to the smallness of their size, and uni. formity of colour and sculpture, that many which inhabit this district may have escaped observation. The present species is one of the most common. Road sides near Craiglockhart. Libberton. Meadows at Restalrig, &c. &c. O. sulcatus, Steph. With the preceding, not scarce. O. rugosus, Kirby. Staph. rugosus, Fab. Marsh. Frequent. The elytra are sometimes rufous. Banks of the Water-of-Leith a little above Dean House, under stones, very plentiful. March. O. nitens, Steph. Not so common as some of the preceding. Figget Whins. Roads about Duddingston. O. piceus, Grav. Staph. piceus, Linn. Marsh. Occasionally found under stones and in pastures. King's Park. Wall tops near Lochend. O. pallipes, Kirby. A minute species, seemingly not rare. O. angustatus, Kirby. Not easily distinguished from the last, in company with which it may sometimes be found. O. opacus, Kirby. Pretty common FAM. OMALIDÆ. а Gen. EvÆSTHETUS. E. nigro-æneus, Kirby. Syntomium nigro-æneum, Curtis. This species was discovered by the Rev. Mr Kirby, and having been taken but seldom since, it is a desideratum to most of the English collections. It is probable that it is not very scarce in Scotland, but it is difficult to detect, as it is rather minute, and usually concealed among moss. It was found last May on the wall at the bottom of the rock at Craiglockhart. It has likewise occurred oftener than once at Raehills, Dumfries-shire. Gen. PROTEINUS. On the flowers of the hawthorn in May, near Slateford. It is not common. Gen. ANTHOBIUM. On the flowers of plants. On the flowers of the hawthorn at Slateford. On the flowers of the broom by the side of the canal, near the bridge No. 8., very abundant. June, July A. grossum, Steph. Omalium grossum, Kirby. A few specimens of this insect have been taken among grass at Inveresk. It occurs both in Roxburghshire and Dumfries-shire. Gen. ELONIUM. Met with in such situations as the Oxyteli, but it is not frequent in its occurrence. Pathways and road sides near Craigmillar Castle. Gen. OMALIUM. O. florale, Steph. Staph. floralis, Payk. Common on wall tops in company with Oxyteli and Aleocharæ. It may be found in that situation in mild weather even in the middle of winter. O. rivulare, Grav. Staph. rivularis, Payk. Marsh. With the last plentiful. Walls by the side of the Waterof-Leith. Sea-shore at Newhaven. March-November. Gen. LESTEVA. L. obscura, Samou. Carabus staphylinoides, Marsh. Under stones and weeds in moist places, sometimes even under water. Ditch by the road side at the west end of Braid Hill, in considerable plenty, last May. The handsome and rare species L. Leachii, so admirably figured by Mr CURTIS, Brit. Ent. pl. 303, has been taken several times at Raehills, Dumfries-shire.

XXIV.- Remarks on the Phenogamic Vegetation of the River Dee, in Aberdeenshire. BY WILLIAM MACGILLIVRAY, A. M. (Read 2d April 1831.) Whatever light may have been thrown on the geographical distribution of plants, by the botanists of continental Europe, in our island the cultivation of descriptive botany seems to have excluded the other branches of the science, and the utmost extent of our knowledge of the distribution of species is limited to a few particular remarks accompanying the description of specific forms in our lists or floras. The time must no doubt come, when a different system will prevail : but in the mean time, an attempt to describe the vegetation of a particular natural district, may excite persons better qualified than I profess to be, to present detached pictures of the vegetation of Scotland, from which a complete panorama may ultimately be constructed. The principal sources of the Dee are found in that part of the district of Braemar which is contiguous with Badenoch, and the north-eastern extremity of Perthshire, in the midst of the Grampians, and nearly in the centre of Scotland. The two principal branches, which unite about three miles above the Linn, to form what is properly called the |
