Show 510 LORD WALSINGHAM ON THE [Nov. 17, margin ; 7 and 8 one after another out of 6, the one before, the other behind the origin of 5, 7 to costa; 9, 10, and 11 separate; a small supplementary cell caused by the continuation of 6 to between 10 and 11. Hind wings narrow, evenly lanceolate, acuminate ; with very long cilia extending to the base of the costal margin. Neuration: 8 veins ; 3 and 4 separate ; 5 and 6 from a common stem, 6 to apex ; 7 parallel with 6. Abdomen somewhat flattened. Legs with the hind femora much flattened and somewhat concave at their outer sides; hind tibiae hairy. This very inconspicuous and ordinary-looking Tineid differs entirely in its structural characters from any genus or subfamily hitherto described ; the neuration is very peculiar, somewhat resembling that of QZcocecis, Gn., to which, however, it is not allied. A single female, possessing the same remarkable neuration which characterizes this genus, differs in the structure of the palpi and in the slightly greater expanse and breadth of the wings. Having at first regarded it as a separate species, I am now strongly convinced that it is but the other sex of Dendroneura prcestans. A description, so far as it indicates structural differences, is appended : - Labial palpi porrected, scarcely twice the length of the head; second joint with a projecting brush of scales below, a pecten of three or four separate hairs on its outer side near the apex; apical joint smooth, short, scarcely more than half the length of the second joint, not recurved nor erect. Abdomen laterally compressed ; ovipositor extended, long. If any reasonable doubt can be entertained as to the identity of this female with the male on which the genus is founded, it must be based upon the difference in the shape of the head, which is of the ordinary form, not flattened or fringed at the side in the manner so remarkable in the type. DENDRONEURA PR^STANS, sp. n. Antennae and palpi pale greyish ochreous. Head pale greyish ochreous ; face shining white. Thorax dull greyish ochreous. Fore wings dull greyish ochreous, with a narrow transverse line of slightly raised brownish fuscous scales before the apex, at the upper end of which is a minute oblique spot of similar scales turning backwards from the costal margin; cilia dull greyish, with an ochreous tinge. Hind wings pale greyish, with a slight ochreous tinge; cilia greyish, tinged with ochreous towards their apex. Abdomen rather shining, ochreous. Legs shining, pale cinereous; tarsal joints unspotted.
