Show 1891.] MICRO-LEPIDOPTERA OF THE WEST INDIES. 503 CACOCHARIS, gen. n. (Kcucdy/ipis=ill-omened.) Type, 3 $ Cacocharis albimacula, Wlsm. (Plate XLI. fig. a, b.) Antennae not more than half the length of the fore wings, simple in both sexes. Palpi placed rather wide apart, short, projecting but little beyond the head; second joint somewhat dilated at the apex above and beneath ; apical joint short, distinct. Head moderately crested above. Thorax with a strong erect crest posteriorly. Fore wings rather ovate, costal margin slightly arched, 3 without a costal fold, apex obtuse, apical margin not indented nor oblique, anal angle rounded. Neuration : 12 veins, all separate; 3 bent up towards 4 on the apical margin ; 6 slightly bent down towards 5. Hind xvings trapezoidal, apex rounded, somewhat bulged between the apical and dorsal margins. Neuration : 8 veins; 3 straight, 4 from the same point as 3, bent upwards towards 5 on its basal half; 5 closely approximate to 4 at the base. Legs with the hind tibiae stout, somewhat clothed. This genus is intermediate between Pcedisca, Tr., and Penthina, Tr., approaching the latter in the possession of a thoracic tuft and in having veins 3 and 4 of the hind wings from a point; in all other respects it belongs to the group of Pcedisca, but is without a costal fold. CACOCHARIS ALBIMACULA, sp. n. Antennae and palpi reddish brown. Head reddish brown. Thorax reddish brown, with a conspicuous bright chestnut tuft posteriorly, preceded and followed by some whitish scales. Fore wings rich chestnut-brown, with a conspicuous white costal patch about the middle of the wing, containing two or three minute black streaklets on the extreme costal margin; mottled with fuscous and purplish-grey patches ; the white costal patch is preceded and followed by a fuscous tinge; a brownish patch lies on the outer half of the fold, and a blackish patch of somewhat raised scales near the base of the dorsal margin is surrounded by purplish grey ; about the outer end of the brown patch is another space of purplish grey, and between this and the apical margin another transverse patch of the same colour, somewhat paler ; one or two very faint pale oblique streaklets, from the costa before the apex, are joined to a slender pale line along (the margin at the base of the cilia, which, however, does not reach the anal angle; cilia brown, tipped with fuscous. Hind wings fuscous, with an iridescent tinge; cilia fuscous. Abdomen fuscous. Legs pale greyish cinereous; hind tarsal joints spotted with fuscous. Exp. al. 14 millim. |
