846 DR. A. G. BUTLER ON 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 ; antenne pale sericeous brown. Under surface 
of wings sericeous pale brown, darker towards costal area, some- 
what 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.

134. THYRETES PHASMA, sp. n. 
Q. Very close to 7. 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 the secondaries is also 
narrower. Expanse of wings 37 millim.

“‘ Fairly common, a day-flyer, sits on grass-stalks” (R. C.). 
DICTENUS, gen. nov. 
Allied to Setinochroa, of exactly the same form; but differing 
utterly in the character of the antenne, 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 Setinochroa and more divergent ; secondaries with the sub- 
costal furca considerably shorter and the footstalk consequently 
very much longer than in that genus. 
136. Dicrenvus Inconsrans, 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: wirgs 
below nearly as above, but the secondaries with a small blackish 
spot at the end of the cell: body below black; tibie and tarsi of 
middle and hind legs ochreous tipped with black. Expanse of 
wings 20 millim.
