Show 1891.] FROM SOUTH-WESTERN AFRICA. 93 less distinct in the smaller, paler specimens). Fore wing: costa edged with creamy in basal fourth, and beyond that by a very slender black line ; a small black mark on costal nervure at base ; 1st discocellular spot close to base, 2nd about middle of cell; a small extra-cellular spot occurs immediately below the middle cellular spot in both wings of one of the larger examples, and (minutely) in the left wing of the two smaller examples ; 6 spots in oblique discal row, of which the 6th (wanting in one of the larger examples) is considerably before and smaller than the rest and situated just below 1st median nervule, while the 4th and 5th are slightly before the upper three. Hind wing : ground-colour paler than that of fore wing, but in the two large examples much clouded with pinkish red, most developed beyond discal series of spots (in which part there exists a faint tinge of the colour in the smaller examples) : 1st discocellular spot at base, 2nd nearer to it than to terminal spot (which is slender and sublunular) ; three other sub-basal black spots, one immediately above, the others immediately below discoidal cell; discal series consisting of 8 small spots, of which the 1st is considerably the largest, close to costa, and (as well as the 8th, on inner margin) situated far before the rest, and the 6th (between 1st median nervule and submedian nervure) is sublunular, elongate, and a little before the 5th and 7th ; neuration between sub-marginal and hind-marginal black streaks more or less defined with black. Cilia as on upper-side. Head fuscous above, creamy, or creamy and fulvous-ochreous, frontally ; a white line round the eyes ; palpi fuscous above, ochreous-creamy beneath ; antennse fuscous above, creamy-whitish beneath, the tip and the underside of the elongate incrassation chestnut-red. Thorax black above, with fulvous-ochreous collar and creamy-ochreous pterygodes-creamy-ochreous mixed with white beneath. Legs creamy-ochreous throughout. Abdomen above and laterally paler or deeper fulvous-ochreous, beneath paler; an inferior lateral black line, bordered on each side by a series of white marks. 2 . Like cf. Fore wing : upper three spots of discal series of underside well represented and completely united, so as to form a conspicuous, transverse, fuscous streak, about midway between terminal discocellular spot and hind-marginal border ; base with a moderate fuscous suffusion ; inner edge of hind-marginal border more deeply indenting ground-colour on nervules. Hind wing : a moderate basal fuscous suffusion ; spots of underside better indicated than in male ; apical fuscous and submarginal streak well-developed. U N D E R S I D E . - A s in larger males ; but silvery-marked submarginal streak broken in fore wing into six quite separate spots, and pinkish-red clouding of hind wing, though generally diffused, not so bright, especially just before submarginal streak. 2 cf (smaller and paler), Omrora, November. 2 cf (larger and brighter), Okavango River, December. 1 2 J Otiembora, between 20th November and 2nd December. The amount of variation in so small a number of specimens is very noteworthy, and indicates the unstable condition of a species to all |
