British Species of the Genus Gelechia of Zeller. 179 in the groove of the wing, is a thin black streak having white intervals. Beyond the middle is an acutely-angled buft" fascia, from the costal end of which round the posterior margin to the anal angle are seven or eight long black dots, placed on a buff ground : cilia grey-brown. Posterior wings silver-grey, cilia con-colorous. Body griseous. This moth sometimes varies in having on the anterior wings more small black streaks than those I have mentioned. I bred two on the 28th June, 1848, from larva found in leaves of sallows, and took two on 11th July in the evening flying about sallows at Dulwich wood. It is also in the Bentley cabinet, taken, Mr. Westwood says, in the north of England. XXXV. Descriptions of some neio Species of Coleoptera. By J. F. S. Parry, Esq., F.L.S., &c. [Read 5lh February, 1849.] Family LEBIAD^. Genus Physodeka, Eschscholtz. Physodera Eschscholtzii. (Plate XVIII. fig. 2.) Phys. niger, nitidus, caeruleo-tinctus ; thorace cyaneo ; elytris splendide cupreis, marginibus viridi-caeruleis. Long. corp. 3|-lin. ; lat. 1| lin. Inhabits Ceylon and the Philippine Islands. Although the present insect wants the bladder-like swelling on either side of the thorax, which characterizes the species on which Eschscholtz founds his genus Physodera, it nevertheless agrees so closely with that insect in all other particulars, that I do not hesitate to place it in the same genus. One is naturally led to question whether the swellings on the thorax may not be a sexual distinction, but on this point 1 have not been able to satisfy myself. Both species, viz. the P. Dcjeanii and the P. Eschschollzii, were brought by Mr. Cuming from the Philippine Islands,* and are now deposited in the collection of the British Museum ; and, upon • Wy own specimen of the P. Eschsclmltsii is from Ceylon.
