64 Mr. J. O. Westwood on the Wing Veins of Insects. I have only to add that the final remark of Mr. Newman quoted above is a fallacy. The term radius has not the priority over that of nervures, or veins, for the organs in question. Jurine, who first proposed the term radius, employed that of nervures for the organs in question. *' Ayant etudie les ailes des hymenop-teres et des dipteres, j'ai remarque que leurs nervures formaient un reseau cellulaire, &c." (N. Meth. class Hym., p. 2) ; and after describing the two strong parallel nervures at the anterior margin of the wing, he says, " Ces deux nervures n'ayant pas encore re9u de nom, j'ai juge qu'il etait necessaire de leur en donner un : — en consequence j'ai donne celui de radius a la nervure ex-terna et celui de cubitus a I'interne" {Ih'id. p. 3). P.S. Since these notes were written a remarkable memoir by A. H. Haliday, Esq., on the same subject, and in which the vein theory is also maintained, has appeared in the Dublin Natural History Review. VIII. A Revision of the British Atomarise; with Observa-tions on the Genus. By T. Vernon Wollaston, Esq. M.A., F.L.S. [Read 5th January, 1857.] Having paid some little attention, during the last few years, to our native Atomariee, I propose, in the following paper, to lay before the Society an enumeration of the species which have been hitherto ascertained to inhabit the British Isles. The con-fusion which has unfortunately arisen through the inaccurate identifications of the late Mr. Stephens, whose collection (now in the British Museum) must moreover be regarded as the sole interpreter of his very meagre and unsatisfactory diagnoses, has rendered the task a somewhat tedious one ; nevertheless, a careful collation of liis entire series (amounting, however, to only 1 1 1 specimens in all), in conjunction with the assistance which I have derived from the material which various friends (amongst whom Messrs. Waterhouse, Janson, Douglas, Murray and Morris Young, should be particularly mentioned) have placed in my
