Cidaria purpurifera, n. sp. 
Male.—Primaries above with a very broad central belt, having a broad 
projection extending to near the subterminal line between the first and 
third median nervules ; the outer margin of the projection in the form of a 
bracket |; central area of the belt traversed by a broad pale purplish band, 
edged on each side by a thin and very irregular sinuated and indented 
dark chocolate-brown line; on each side of the purplish band, and occupy- 
ing the spaces between it and the inner and outer margin of the central 
belt, is a narrow band of olive-green mottled with dark chocolate-brown, 
the part within the projected portion of the central belt being entirely filled 
up with dark chocolate-brown ; the outer and inner margin of the central 
belt irregularly sinuous and indented, and edged with a thin line of dark 
chocolate-brown ; subterminal line white and crenate, and having blotches 
of dark chocolate-brown between some of its angles; the space between the 
central belt and the subterminal line olive-green next the central belt, with 
a very conspicuous suffused white line, broadest between the costa and the 
projection of the central belt; external border olive-green, suffused near 
the apex with dark chocolate-brown; a marginal line of dark chocolate- 
brown lunular spots, edged with white; basal patch olive-green suffused 
with brown at its outer margin which has angles and indentations similar 
to those uf the inner margin of the central belt; space between basal patch 
and central belt paler olive-green, suffused with white on its outer margin; 
an apical costal patch of pale olive-green diminishing from the subterminal 
line to a point at the apex, and suffused externally with white; central spot 
absent; cilia chequered with dark chocolate-brown and whitish. Primaries 
below with a band of three dusky sinuous and dentated parallel lines be- 
yond the middle, the lines dark and distinct on the costa, but fading 
towards the inner margin of the wing; the space between the outer of 
the three lines and the base, pale brown; the space beyond the outer line 
similar to the upper side but paler, and having pale brown in the place of 
the olive-green ; basal half of costa irrorated with dark chocolate-brown ; 
marginal line of lunular spots and chequered fringe as on upper side; a 
distinct discocellular spot formed by a short transverse streak; in some 
specimens the markings are much more indistinct and in some almost 
obliterated. 
. Secondaries above tawny-ochreous, with three very indistinct transverse 
sinuous and dentated parallel lines a little before the middle of the wing ; 
outer margin edged with a very thin line of darker ochreous; cilia not
