Show 846 DR. A. G. B U T L E R O N LEPIDOPTERA [NOV. 17, fringe blackish, tips shining dark vinaceous : body deep chocolate-brown, sprinkled with shining leaden scales; the posterior edges of the collar and bases of the metathoracic and abdominal tufts somewhat ochreous ; antenna? pale sericeous brown. Under surface of wings sericeous pale brown, darker towards costal area, somewhat vinaceous, fringes distinctly so; primaries blackish in the cell and with a glistening internal area: body below glossy vinaceous chocolate-brown, the extremities of leg-joints and the last joint of the palpi somewhat ochraceous. Expanse of wings 82 millim. Deep Bay, Feb. 5th, 1896. 134. THYRETES PHASMA, sp. n. 2 . Very close to T. caffra, but easily distinguished from the fact that the hyaline triangular spot in the cell of primaries fills the upper instead of the lower angle; also the inner edge of the hyaline belt from median vein to apex is not irregular but forms a direct oblique line, the second division from the apex being much elongated backwards ; the brown border of tbe secondaries is also narrower. Expanse of wings 37 millim. Deep Bay, Feb. 18th, 1896. " Pale green ova " (B. ft). 135. ARGINA OCELLINA. Deiopeia ocellina, Walker, Cat. Lep. Het. ii. p. 571 (1854). 6* 2 , Deep Bay, Feb. 27th, 1896. "Fairly common, a day-flyer, sits on grass-stalks" (B. ft). DICTENUS, gen. nov. Allied to Setlnochroa, of exactly the same form; but differing utterly in the character of the antenna?, which are solidly bipec-tinated, the pectinations widely separated and emitting short bristles: the primaries with only four branches to the subcostal vein, the fork of the united third and fourth branches being longer than in Setlnochroa and more divergent; secondaries with the subcostal furca considerably shorter and tbe footstalk consequently very much longer than in that genus. 136. DICTENUS INCONSTANS, sp. n. (Plate XLII. fig. 5.) Wings bright ochreous, the primaries with a conspicuous black spot at the end of the cell; basal half of costal border black; the remaining half sometimes black, as well as a broader outer border and narrow internal border: body black, collar, pterygodes, and metathorax clothed with ochreous hair; anal tuft ochreous : wings below nearly as above, but the secondaries with a small blackish spot at the end of the cell: body below black; tibia? and tarsi of middle and hind legs ochreous tipped with black. Expanse ot wings 20 millim. Kasungu Mountain, 7125 feet alt., Nyika, March 2nd and 5th, 1896. |
