Show 522 LORD WALSINGHAM ON THE [Nov. 17, Legs very pale cinereous; hind tibiae very pale cinereous, shaded with brownish fuscous externally ; posterior tarsal joints fuscous, dotted with white ; spurs pale cinereous; the middle pair of legs are blackish, with slender white oblique lines on their outer sides. Exp. al. 10 millim. Hab. West Indies-St. Vincent (May, 1 specimen, Smith). Type, 3. DIDACTYLOTA, nom. n. (&'s=twice ; £aKr^\wrds=fingered.) = § Dactylota, Snell. Tijd. v. Ent. xix. pp. 23-7 (1876). Type, 3 2 Dactylota kinkerella, Snell. The name Dactylota, given by Snellen to this genus, being preoccupied by Brandt in the Echinodermata (1835), I have thought it desirable to change it to Didactylota, a name which if read in a certain sense is sufficient to indicate its origin, but which equally applies to the structure of the genus. DIDACTYLOTA BICOLOR, sp. n. Antenna? pale fawn. Palpi very pale fawn. . Head and thorax rich fawn-brown. Fore wings rich fawn-brown to very near tbe middle, beyond fuscous speckled with pale cinereous; the margin of the two colours is straight and distinct across the wing, but with no dividing-line; cilia pale cinereous, with a line of fuscous scales along their middle. Hind wings pale greyish fuscous; cilia long, purplish grey. Abdomen fuscous, pale cinereous beneath; the protruding anal claspers white. Legs pale cinereous, with long greyish hairs on the hind tibiae above, projecting over the spurs; hind tarsal joints barred with fuscous. Exp. al. 7\ millim. Hab. West Indies-St. Vincent (windward side, 1 specimen, Smith). Type, 3. This is the third species of the genus now known. The hind wings distinctly divided to one fourth into two separate lobes, seems to justify its position. In a single specimen I am unable to examine critically the neuration, but it appears to be in all respects similar to kinkerella; the wings, however, owing to their very long and closely packed cilia, have a squarer appearance, which makes them look wider in proportion to their length ; this, however, is not the case when the shape of the wing itself is examined. In this and the American species (snellenella, Wlsm.) the second lobe of the hind wings is somewhat more decidedly developed than in the European type. |
