reduciag the marginal tawny border of the primaries to a series of 

 oval spots ; the secondaries somewhat produced at anal angle, with 

 the inferior tail slightly incurved, but both tails well developed and 

 only slightly shorter than in C. lasti : below, the wings are much 

 paler than in the male, the silver band of secondaries being replaced 

 by a broad creamy stramineous belt in continuation of that on the 

 primaries. Expanse of wings 18 millim. 



Two pairs, Zomba. 



This species is intermediate in character between C. lasti and 

 C rynthia.

The single specimen obtained is distinctly shot with dark bronze- 

 green on basal area and indigo-blue on external area ; the white 

 band tapers 7nore than usual on the primaries, the five upper spots 

 being smaller than in most examples. This species is, however, 

 known to vary ia all these characters.

Hewitson's description of his Nyasa example is insufficient to 

 enable anyone to distinguish it from the true male of C. azota 

 from Delagoa Bay : the latter is smaller than examples from 

 Nyasaland, and on the upper surface of the primaries the reddish- 

 tawny border divides above the second median branch, the inner 

 furca consisting of five and the outer of six spots ; in the Nyasa 

 form the border divides above the third median branch, leaving 

 only two and a half spots of the inner furca free ; the remaining 

 divisions of the border are also marked with black spots : on the 

 secondaries the outer red area occupies nearly half the wing in the 

 male from Delagoa Bay, but in V. nyasana only two-fifths, in 

 the former the inner edge of this border is nearly straight ; in the 

 latter it is zigzag. On the under surface the shiny glaucous lilacine 

 central band in 0. nyasana is of double the width of that in 

 C. azota : expanse of wings in the former 95 mdlim., in the latter 

 87 millim. 



O. calliclea, H. G. Smith, is an intermediate race. 



12. Chaeaxes leoniktjs, sp. n. (Plate XV. fig. 2.) 



Allied to C. nichetes, similar in form. Above deep orange, tawny 

 in the male, paler in the female ; a single or double black spot in 

 the cell of primaries just below the subcostal vein, a transverse 

 subcuneiform spot at end of cell, two quadrate spots beyond the 

 cell, and three smaller spots in the median interspaces ; a black 

 zigzag discal band, diffused on both sides towards costa and bounding
