dark grey edged with black. Between these two stigmata isa trace 
of an indefinite perpendicular band of dark grey shading right 
across the wing. Fringes grey with a dark dividing line. Thorax

@. Primaries pale greyish-cinnamon-brown, first line close to 
base indistinct reddish-brown, second line waved reddish-brown, 
third line very indistinct, followed by a curved row of white dots, 
from whence the ground colour of the wing becomes abruptly 
darker up to the hindmargin, which is finely edged by a light line, 
and preceding which is a series of dark grey shadings between each 
nervule. Orbicular stigma distinctly encircled with reddish-brown, 
as is the reniform, the latter being filled in with greyish. Between 
these two stigmata there is a perpendicular band of dark reddish- 
brown shading right across the centre of the wing, and a similar 
coloured patch is in front of the apex. Fringes brownish-grey. 
Secondaries brownish-grey, darker near the hindmargin. Fringes 
pale grey. Thorax as primaries, abdomen as secondaries. Exp.

36. Mamestra afra, sp.n. (PI. L., fig. 7.) 
Primaries pale ochreous-grey, the first line close to the base is 
black, toothed, extending from the costa to the submedian vein, and is 
followed by a whitish stripe; second line in front of the orbicular 
stigma is composed of three crescentic dark marks starting from a 
dark grey costal spot, the central and inner crescents being preceded 
by a whitish edging. Orbicular stigma white, beneath which is a 
small dark crescent touching the middle of the second line and so 
making the letter q below the stigma. Reniform stigma margined 
with black, except on the costal side, with a basal inner margin of 
white and filled in with dark grey, except at the apical corner, 
where the colour is ochreous-grey. Subterminal line, consisting of 
a very strongly serrated fine dark line, bordered externally by 
white, is curved out beyond the reniform stigma, but terminates 
on the inner margin nearer the base than is that stigma. The 
terminal line close to posterior margin, strongly serrated, is white, 
edged internally by a dark shading, and with a dark patch opposite 
the reniform stigma. The hindmargin is conspicuously edged with 
dark crescentic marks between each vein. Fringes grey tessellated 
with white, and having a dark dividing line; on the costa are seven
