Show 18/5.] MR. W. H. HUDSON ON THE HABITS OF HERONS. 623 much darker in colouring ; primaries much more grey in tint; costal margin pale brown, not white ; all the bands narrower, the pale lines, and the broad pale band much narrower, the latter intersected down the centre (not within its inner half) by a brown line ; secondaries almost black, the red band much deeper in colour and half the width ; body darker ; the sides of the abdomen brassy rather than reddish golden : wings below darker, external border much greyer; sides of venter more yellowish golden : expanse of wings 3 inches. Ceylon (Skinner). Type, coll. F. Moore. This is a well-marked southern representative of C. rosina. 2. CHCEROCAMPA PUELLARIS, n. sp. Nearly allied to C. oldenlandice, considerably smaller, and altogether paler in colouring; primaries comparatively broader and shorter; the bands broader and slightly waved ; secondaries with the pale band wider and whity brown ; body with the bands broader, silvery border of tegulse strongly marked : wings below paler, external border whiter; pectus whiter, venter without longitudinal central whitish streak : expanse of wings 2 inches. Rawul Pindi (Hellard). Two examples, coll. F. Moore, This is a well-marked and interesting little species. 3. CHCEROCAMPA INTERSECTA, n. sp. Nearly allied to C. silhetensis, but narrower in the wings; the black oblique band of primaries narrower and straighter; the pale buff band almost immediately following it considerably narrowed, owing to the fact that the innermost of the five discal dusky lines is placed further from the margin, and consequently runs exactly through its centre ; pale rosaceous band of secondaries broader, more uniform in width ; body darker above, lateral streak on abdomen less golden, dorsal line more silvery; markings below less defined : expanse of wings 2 inches 6 lines. Queensland (Janson). Type, B.M. This is evidently the Australian representative of C. silhetensis. Genus DILUDIA. Under this genus I should wish to correct an error which has accidentally crept into a former paper. P. Z. S. 1875, p. 260, n. 57 : For Diludia rufescens, read Diludia rubescens. This is important, as the name rufescens has been used before. 9. On the Herons of the Argentine Republic, with a Notice of a curious Instinct of Ardetta involucris. By W . H. H U D S O N , C.M.Z.S. [Received October 30, 1875.] I have observed Herons a great deal, and am strongly inclined to adhere to Buffon's opinion that they are wretched, indigent birds, PROC. ZOOL. Soc-1875, No. XL. 40 |
