On the Periods of Flowering of certain Plants. 223 all the interstices flat and broad, and all very sparingly clothed with short, suberect whitish scales, and by the anterior tibia being armed with a long spine near the apex without, and with two diverging spines in front. According to Sckonherr, Tr. spinimanus (which is described by Gyllenhal apparently from a native insect*) is synonymous with Tr. scaber {scabriculus of Linn.f), but my foreign specimens of Tr. spinimanus from Germar himself are very different from sea-briculus of Linn., and very distinct. Although I have taken many specimens of Tr. alternans in different localities, yet I never met with a specimen of Tr. spini-manus ) it appears to be very rare ; specimens in the cabinet of Mr. Waterhouse were found I think near Cromer, Norfolk, and I am indebted to him for a specimen ; I have seen specimens in the cabinet of Mr. Stephens. XXVI. — Comparison of the Periods of Flowering of certain Plants in the early Spring of 1846, in the Botanic Garden of Belfast and the Jardin des Plantes at Paris. By William Thompson, Esq. (Belfast). To the Editors of the Annals of Natural History. Gentlemen, Although fully sensible that the following very brief commu-nication on a highly interesting subject is almost too trivial for publication in the ' Annals,^ I send it forward under the impres-sion that possibly it may be considered worth the little space that it will occupy. Belfast, Feb. 27, 1847. Wm. THOMPSON. A PAPER by M. Ch. Martins appeared in the number of ' Annales des Sciences Naturelles' for April last, on the subject of the extraordinary temperature of the winter of 1846, and its influ-ence on the flowering of plants. Lists of the species which flowered in the Botanic Garden of Paris at certain periods of that season being given, they suggested to me the desirability of drawing up similar lists respecting the Botanic Garden at Belfast. These compared with the others exhibit some interesting results, although the number of species noted down in the latter locality falls far short of what could be wished. The information re-specting them was derived from Mr. D. Ferguson, the able cu-rator of the Garden — who also supplied the few notes respecting Glasgow.
