 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 hue 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 hues a httle before the middle of the wing ; 

 outer margin edged with a very thin line of darker ochreous ; cilia not
