12 ME. G. T. BETHUNE-BAKEB : A EE VISION OF THE 



that de Niceville (/. c.) has quite correctly elucidated them. This species may be known 

 from all others by the absence of the silvery-white patch at right angles to the body, 

 just below the costa in the secondaries. It seems to obtain in precisely the same 

 district as timoleon. It would be an interesting life-history to work out, and so prove 

 the correctness of de Niccville's theory that it is the dry-season form of that species.

d . Upperside : both wings brownish black, with the blue patches of a pale metallic 

 azure, not the deep blue of the previous two species. Two tails, tipped with white, one 

 at the lobe and one from the end of the lower median nervulc ; there is also a tooth-like 

 excrescence at the end of the second median nervule. Underside : primaries dark grey 

 with the internal margin quite pale ; a silvery-white stripe along the upper discoidal 

 nervure terminating a third before the end of the cell, which is closed by a like- 

 coloured spot, beyond which is a curved row of three silvery-white spots, the lowest 

 being the most outward and forming at the same time the uppermost of a row of three 

 straight, very oblique (inwardly), white spots ; the ground beyond the curved row is red 

 up to the submarginal row of white spots, which row is curved outwards in the centre, 

 while beyond this the margin is slightly rufous, and the costal area is also somewhat 

 rufous. Secondaries with the basal half brightly rufous, the extreme basal costa being 

 shortly white ; from the base there is a very broad band of creamy silvery touching the 

 costal nervure at and beyond its middle, which sends a creamy stripe to the upper 

 median nervule, thus closing the cell ; a toothed whitish stripe runs from the base of 

 the second median nervule to the upper part of the abdominal margin. This rufous 

 area is edged by an irregular, somewhat interrupted, curved stripe of whitish, on the 

 outer margin of which is a row of four or five very deep red, lunular, small spots 

 extending as an interrupted red stripe to the abdominal edge, beyond which is a broad 

 band of neutral grey tapering and narrowing towards the costa and ending in a small red 

 patch: outside this is a marginal row of spots, the lobe-spot and three beyond it being
