446 MR. P. L. SCLATER ON BIRDS FROM [May 20, depression ; antennae and lower part of face obscure ferruginous, the third joint of former not much longer than the second, the fourth joint the longest. Thorax with the anterior angles but slightly produced and rounded; surface finely punctured, shining testaceous or flavous. Elytra widened behind, rather deeply and very closely punctured, with a distinct longitudinal depression in the middle of the base ; the latter narrowly ferruginous, which colour also extends in form of a longitudinal short streak down the shoulders to about one third the length of the elytra ; another sutural semi-square spot is placed below the scutellum, while a transverse short fascia occupies the middle, and another similar-shaped spot is placed near the apex of each elytron. Neither of these markings touch the suture or the lateral margins. Claw-joint strongly inflated. Hub. Irazu Mountain, Costa Rica, and Nicaragua. 16. CEdionychis septemmactjlata, sp. nov. Piceous below ; lower part of vertex, thorax, and elytra testaceous, the latter with seven black patches, viz. two at the base, one common to both elytra before the middle, the other four at the middle and before the apex respectively. Length 3 lines. Vertex impunctate, lower part of the latter, as well as that of the clypeus, testaceous ; antennae piceous, basal joints paler. Thorax rather convex, sides broadly margined, the anterior angles produced into a short tooth ; surface minutely punctured, testaceous ; scutel-lum obscure piceous : elytra narrowed at base and apex, broadly margined, with two short longitudinal depressions at their posterior half, more distinctly punctured than the thorax, of a light testaceous colour, with the patches of the following shape — the basal one ob-liquely cut at its posterior margin, the sutural one of triangular shape, followed closely by a transverse quadrate fascia, and the apical one also of a transversely subquadrate shape ; none of these mark-ings touch the sutural or the lateral margins. Claw-joint greatly dilated. Hah. Peru. 2. On a Fourth Collection of Birds made by the Rev. G. Brown, C.M.Z.S., on Duke-of-York Island and in its vicinity. By P. L. Sclater, M.A., Ph.D., F.R.S., Secretary to the Society. [Received May 2, 1879.] (Plates XXXVI., XXXVII.) I have now again the pleasure of laying before the Society a series of bird-skins collected by our excellent correspondent Mr. Brown on Duke-of-York Island and on the adjacent parts of New Britain and New Ireland.
