Show 1880.] LORD WALSINGHAM ON NEW TINEID.E. 89 PSECADIA SUBCERULEA, sp. nov. (Plate XII. fig. 5.) Prcecedenti affinis; alis anticis subcceruleo albis, lineis et irregularibusfumosisprcecipue supra trientem dorsalem conspersis; margine dorsali peranguste fumoso. This species differs from the last named (Psecadia arctostaphy-lella) in its slightly larger size, and in the absence of any generally connected shade over the costal half of the fore wings. This is as it were replaced by a series of disconnected smoky blackish streaks of varying size and distinctness. The most noticeable of these are an elongate shade from the base immediately below the costa; a short oblique dash below it also on the basal third of the wing. One or two semicounected parallel streaks along the cell about the middle of the wing; a spot, with three projecting limbs on its outer side, lying between the lower angle of the cell and the anal angle, and a very slender blackish line all along the dorsal margin. The veins surrounding the cell are also more or less indicated by lines of blackish scales. In some varieties, perhaps slightly worn, the markings are much less distinct than in others. It is nearly allied to P. arctostaphylella, and frequents the same probable food-plant, so that a comparison of the larvae would be interesting, in order to establish or to refute the distinctness of the two species ; but it differs, as I have shown, in having no distinctly separate pale and dark portions on the fore wings; and, moreover, in the slender line along the dorsal margin, which does not occur in that species. Expanse 25 millims. cf 2 • Sonoma and Mendocino counties, California, May 23rd and June 13th, 1871. PSECADIA ALBISTRIGELLA, sp. nov. (Plate XII. fig. 6.) Capite et thorace subnigrescenti-brunneis, linea alba circumcinctis alis anticis subnigrescenti-brunneis, striga submedia angusta a basi ad finem cellulce producta furcam brevem gerente, punctis novem marginalibus nigris, posticis paulo pallidioribus; abdomine (postice) et tibiis posticis flavis. Head blackish brown, with a white line on each side above, which is carried round the blackish-brown thorax, forming an angle behind it, with the apex pointing forward. Palpi blackish brown, the apical joint upturned, long, and pointed, a small white spot at the junction of the second and third joints. Antennae more than half the length of the fore wings, blackish brown. Fore wings blackish brown, a narrow white steak of even width running from the base along the lower edge of the cell, and terminating in a short fork at its lower external angle; the lower half of the fork is sometimes obsolete ; there is a row of nine black dots preceding the cilia, three on the costal aud six on the apical margin. Hind wings and cilia very slightly paler than the fore wings. Abdomen bright orange-ochreous except at the base, which is blackish brown. Legs blackish, except the third pair, which are bright orange-ochreous, and have the ex- |
