BUTLER ON NEW [Jail. .*, irregular brownish lines crossing the middle of cell; a broad greyish patch, beginning just before end of cell, bounded internally by a blackish streak, and bounded and crossed externally by two lunulated waved transverse lines running from costa to inner margin; two similar discal lines, becoming black below third median branch; a very irregular black streak bounding the apical patch, and immediately below it two interrupted blackish lunules; a central submarginal bifid black-edged grey spot; an ill-defined submarginal streak ; a white discocellular spot; outer margin black-spotted ; secondaries smoky brown ; abdominal area testaceous ; outer margin dark brown, broadest at apex ; a pyriform dark brown streak on abdominal area, continued laterally as an indistinct brown streak crossing the centre of wing ; anal angle white, interrupted by two marginal semicircular blackish spots and an irregular submarginal grey streak : thorax pale grey, collar dark grey behind, pterygodes bordered externally with black; metathorax margined behind with blackish; abdomen whity brown, with lateral oblique dark grey and white strigae on each segment: wings below tinted with ferruginous, a common lunu-late and waved discal streak; primaries with a black costal streak just beyond the end of cell; an interrupted submacular brown streak just beyond the discal streak, an oblique white spot at apex; fringe spotted with brown; secondaries crossed above the middle by an oblique diffused brown bar; a brown streak at apex and anal angle, fringe spotted with ferruginous; body whity brown, palpi and pectus white. Expanse of wings 5 inches. Port Natal (Gueinzius). Type, B.M.

Wings above olive-green ; primaries with the base, a broad transverse band leaving a large quadrate costal spot, a small spot between the latter and the base upon inner margin, and an irregular band beginning broad at apex, undulated and narrowed externally to upper radial, then abruptly and deeply excavated to external angle, its inner edge straight and with a pale border, all dark brown; a postmedian squamose snow-white streak bounding the broad subcentral transverse band ; a snow-white point on lower discocellular and two at base ; secondaries with the costal area testaceous ; apical half of wing dark brown; fringe testaceous: body olive-green head greyish brown ; abdomen paler at the sides, with five transverse |
