all less vivid and there is a broad pale belt across the wing 

 which includes the greater part of the discoidal cell, so that 

 the lower ramus of the dark discoidal furca is clearly seen to 

 be bordered on both sides with chrome-yellow; the submarginal 

 yellow spots are rather more elongated than in P. locusta.

? . Curiously resembles Tithorea Pavonii. Above black : 

 the primaries with a broad sulphur-yellow patch, paler 

 externally, commencing just above the base of the median 

 vein and divided by this vein and its first branch, at the 

 middle of which branch it terminates ; below this a diffused 

 yellow streak traversed by the submedian vein ; a slightly 

 irregular pearly white oblique macular band beyond the cell 

 from costa nearly to outer margin, its inner edge angulated at 

 subcostal vein, its last inferior spot small and well divided 

 from the remaining divisions ; two spots placed subapically, 

 the upper one bifid ; a larger spot near posterior angle : 

 secondaries with brown costal area, below which is a broad 

 sulphur-yellow belt, whitish at each extremity, from abdo- 

 minal margin to second subcostal branch, above which are a 

 few yellow scales ; this belt is deeply incised upon the veins, 

 but especially upon what would now be called the " upper " 

 radial ; a submarginal series of white spots. On the under 

 surface the primaries are nearly as above, excepting that there 

 is a pale patch at apex tinted with grey-brownish and yellow, 

 and partly enclosing the bifid subapical spot ; below this and 

 near outer border are three bifid yellow spots, the last being 

 the terminal spot of the postmedian stripe : the secondaries 

 nearly resemble those of the male, but are altogether more 

 vivid in colouring, the broad belt crossing the cell being 

 mostly white and the streak bordering the discoidal < -shaped 

 character (false vein) bright cadmium-yellow. 



Expanse of wings 71 millim.
