Three males, two females. 2nd January.-Thrupp. Only one male was taken less than eighty miles south of Berbera. 46. SYNCHLOE DISTORTA, sp. n. (Plate XLVII. fig. 12.) 2 . Pale sulphur-yellow ; all the nervures above greyish, owing probably to the semitransparency of the wings, which allows the pattern of the under surface to be seen ; costal margin of primaries blackish ; a cuneiform and somewhat curved black patch at the end of the cell, uniting on the third median branch with the apical border, which is formed as in 8. hellica, and encloses similar oval spots of the ground-colour ; the black spot below the first median branch of 8. hellica is here only indicated by a minute blackish dot, and the secondaries show no more of the dentate-sinuate submarginal line than in the male of that species. Below, the wings are decidedly yellower than above ; all the veins are grey-brown irrorated with yellow, which gives them an olive tint: primaries with the patch at the end of the cell formed as above, confluent, with a greyish basicostal border, not black as above, but greyish sprinkled with yellow atoms ; two paler but similarly coloured patches, representing the inner portion of the apical border, but placed further from the margin than in <S. hellica ; submedian dot rather larger than above : secondaries with the veins more broadly bordered than on the primaries, and connected by a submarginal dentate-sinuate yellow-sprinkled grey stripe. Expanse of wings 33 millim. One female. More than eighty miles south of Berbera.-Thrupp. Only one female was obtained, which, from its small size and narrow wings, I at first imagined to be only a starved specimen of some well-known species. Upon comparing it, however, with S. hellica and allies, it is clearly seen to be perfectly distinct, the dark veins of the primaries being peculiar to it. The specimen is in all probability somewhat starved, which would account for its small size and narrow wings ; but the other characters would be amply sufficient to distinguish it specifically. 47. HERP^ENIA MELANARGE, sp. n. S . Nearest to H. tritogenia: smaller, wings blacker, pale markings of a uniform cream-colour ; oblique patch at end of cell less irregular, subapical spots larger; central submarginal spot smaller; dot at extremity of first median inter-pace obsolete ; oblique band from internal margin much narrower, more or less divided above the first median branch ; black band from abdominal margin of secondaries differently shaped, widest instead of narrowest at this margin, its inner edge forming a slight regular arch to the subcostal vein ; outer border broader; apical area of primaries and whole of secondaries below tinted with pink, the markings bronze-brown (not yellowish brown); the pale bands being narrower, and the darker ones consequently broader than in H. tritogenia. Expanse of wings 44 millim. |
