abdomen crossed by narrow interrupted black lines. Wings below pale yellowish brown : 

 primaries with a longitudinal subcostal basal blackish streak ; a very broad area, representing 

 the central belt of the upper surface, broadly bordered with black, its upper portion mottled 

 with black, its lower half crossed by a longitudinal black belt ; nine pale-edged slender blackish 

 lines from costa to inner margin, followed by a black regularly zigzag submarginal line ; 

 external border slightly olivaceous : secondaries with the basal half streaked with black and 

 limited by a recurved black undulated belt ; remainder of the wing as in the primaries : pectus 

 black, sides and coxae brown ; venter sandy brown, with straight central and undulated lateral 

 slender black lines. Expanse of wings 5 inches 9 lines.

Altogether darker and of a yellower tint than the preceding, the central belt with its 

 upper half convex instead of concave externally, the white lines on the subapical area replaced 

 by sagittate white markings in three regular longitudinal series ; all the black lines wider : 

 secondaries with the basal area nearly as wide again, black, excepting towards the costa, which 

 is purplish brown, only streaked with ochraceous brown towards the abdominal margin, its 

 outer edge less sharply angulated ; the disk crossed by slate-coloured streaks intersected by 

 white Hues ; the submarginal shell-like ocelli more depressed, and consequently more evidently 

 confluent ; as in the primaries, they and the outer border are more olivaceous in tint : the 

 body above is black, the thorax longitudinally streaked with ochraceous, the abdomen banded 

 with the same colour and with a dorsal median stripe of it. Below, the representative of the 

 central belt on the primaries is much more suffused with black ; the basal area of secondaries 

 is black, only streaked with buff towards the costal margin, the discal lines are much less 

 strongly undulated, and the submarginal line is not zigzag ; the pectus is wholly black, and 

 the venter ochreous with black longitudinal lines. Expanse of wings 6 inches 2 lines.

Differs from the preceding in its altogether redder colour, the much greater width of the 

 central belt of the primaries, the almost entire absence of all white markings, the lines on the 

 subapical area being extremely slender, lunate, and indistinct, the greater width of the basal
