margin nearly as on fore wing, but with its deepest sinus in front of thence 
running out along DC^, its anterior half extremely weak, punctiform; distal 
area corresponding to that of fore wing. 
Fore wing beneath almost equally suffused and irrorated throughout, the 
costal edge cleaner, more ochreous, dotted or strigulated as above; a very 
small pale apical patch; indications of a cell-dot or small spot (not ring). 
Hind wing rather paler, the cell-spot rather strong but not annular, the other 
markings of upperside reproduced but indistinct. 
Cape Colony: Willowmore, October 1916 (Brauns). Type in coll. Janse. 
There may probably be in some other fauna a “genus” of the Boarmia 
group which would accommodate this species better than Ectropis, but its 
classification as a whole is a matter of extreme difficulty and until it can be 
taken in hand seriously it seems best to follow Warren in calling the ciliate 
species of the group Ectropis. Except for the cell-marks, the crenulate hind 
wing and its strong median shade, the new species recalls I diotephr a” simplex 
Warr. 
40. Chora histonica sp. nov. 
S, 37 mm. In structure similar to spuria Prout {Nov. Zool. xxii. 360), 
antenna pectinate to nearly two-thirds (about 32 joints). Face black, with 
upper part creamy white. Palpus mixed red-brown, black and white. Vertex 
and front of thorax cream-white, with some red-brown admixture. Antennal 
shaft white, irregularly dark-spotted, most strongly from near base to about 
one-third. Thorax red -brown, above mixed with black and more sparingly 
with white; black bands bordering the white front and traversing the tegulae. 
Abdomen white, with strong central spots and irregular belts of red-brown 
mixed with black, the posterior belts more rust-coloured. Legs blackish, 
banded with white, the long hair of the fore tibia mainly white. 
Fore wing white, with quite sparse brown and black irroration ; costal edge 
rather more strongly dusted and with irregular black spots at the origin of 
all the lines; a subbasal at i mm., sharp but only extending from M to SM^; 
antemedian rather fine and sharp, from before one-third costa, obtusely angu- 
lated outward on M, then oblique inward, outbent at SM^, then curving 
inward to hind margin at little beyond one-fourth ; a weaker, interrupted line 
proximally to this, closer to it on hind margin than on costa, the interspace 
partly filled in with brown shading; median beyond middle of costa, thick 
and angulated inward about C and SC, then very oblique outward to behind 
R^, here sharply bent, becoming very fine and obsolescent, bisinuate, touching 
the postmedian at fold; postmedian strong, with minute teeth outward on 
the veins, from beyond two-thirds costa, fairly direct to fold, then thick, 
oblique outward, again tapering to a point at three-fourths hind margin; a 
patch of brown, sparsely black-mixed irroration costally between postmedian 
and subterminal, bounded posteriorly by a more ferruginous spot on R^ 
(distally to which this vein continues faintly ferruginous) ; a thick black 
longitudinal streak outward from postmedian between R^ and R^] a dentate 
white subterminal, scarcely indicated except by faint (only against the brown 
costal patch distinct or blackish) proximal shading; an ill-defined dark spot 
at distal margin between the radials ; a terminal line of partly connected black 
lunules; fringe white, with dark spots at the vein-ends, posteriorly thin, an- 
teriorly thicker. Hind wing with termen weakly subcrenulate, slightly truncate 
between SC^ and M^; white, almost without irroration except at abdominal 
and distal margins; postmedian line present, but much weaker than on fore 
wing, chiefly marked by the vein-teeth and a slender bicurved mark between 
and abdominal margin; proximal shading of subterminal thickened in an
