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
