139 Further Notes on Australian Goleoptera, WITH Descriptions of New Genera and Species. By the Rev. T. Blackburn, B.A. XV. CARABID.E. TACHYS. T. hrightensis, Blackb. This name appears to represent the same species as Bemhidhim striolatwm, Macl.; though the con-clusion could not be arrived at from Sir W. Macleay's description, I think there is no doubt of its being correct, as Mr. T. G. Sloane has recently sent me some examples of B. striolatum (named by comparison with the type), which are undoubtedly my T. hright-ensis. The insect certainly cannot be placed in Beinhidiiim ; it seems structurally to be a Tachys (or very close thereto) although, as I have previously remarked, belonging to a group of Aus-tralian species, that perhaps might with propriety receive a dis-tinctive generic name. SILPHID.^. CHOLEVA. C mitijoodum, Blackb. I have received from Mr. Simson an example of Cholera taken in Tasmania, which I think must be referred to this species, although it is a little more elongate,. and parallel in form, and considerably darker in colour. I take this opportunity to improve my description of the mesosternal keel in this insect, which I said (Trans. Roy. Soc. S.A., 1891, p. 87) "scarcely emerges forward from between the coxre ;" a more correct expression would have been " becomes very feeble in front of the coxa3," LAMELLICORNES. PALMERSTONIA. P. minor, sp. nov. (Fern.) Nitida ; valde convexa ; picea, supra glabra, clypeo la3vi ; prothorace quam longiori dimidio latiori, grosse minus crebre punctulato ; elytris vix manifeste .4-costatis, obsolete seriatim punctulatis, stria suturali leviter impressa ; suljtus (abdomine fere giabro excepto) longe minus-dense hirsuta. Long., 8 1. ; lat., 4 J 1.
