Mr. Trimen, ‘ South-African Butterflies,’ vol. iii. p. 414, 
observes :—‘‘ On careful comparison of two males taken by 
Mr, Selous—which quite agree with Mr. Butler’s description of 
C’. esmeralda—and of three very fine males taken near Durban by 
Mr. Millar, with the type of A. pseudozeritis, I have come to the 
conclusion that esmeralda is identical with pseudozeritis.” He 
then proceeds to point out that his type and specimens from 
Durban are darker below than the others, have a fuscous cloud 
on the middle disc of the hind wings, the silvery spots very 
brilliant, and “There are two linear tails on the hind wing, 
respectively on the first median nervule and the submedian 
nervure.” This, to my mind, settles the question: the Somali 
examples only have one tail ; they are uniformly of a buftish stone- 
colour below without any clouding. I examined an example, pre- 
sumably of C. pseudozeritis, about a year ago, and decided that it 
was undoubtedly distinct. 
14, JoLAUS NURSEI, sp.n. (Plate X. fig. 16.) 
Closely allied to I. umbrosa (P. Z. 8. 1885, p. 766, pl. xlvii. fig. 6), 
but the wings above bright cobalt-blue, with two whitish super- 
posed spots on the disc of the primaries, close to the slaty-black 
outer border ; the fringe much whiter, pure white towards external 
angle: secondaries above with two or three ill-defined white discal 
spots parallel to outer margin; the outer border pure white, 
bounded internally by a dusky stripe, including the ordinary black 
spots, and externally by a sharply-defined black line; fringe pure 
white with a greyish line: wings below pearly white, the pattern 
nearly identical with that of . wmbrosa, but the bands black-brown 
instead of red: other differences which exist may be variable and 
therefore not worth noting. Expanse of wings 35-40 millim. 
66, Shaik Othman, 3rd March and 3rd April, 1895 (Col. 
Yerbury); 3, 26th February, 5 2, 31st March (Capt. Nurse). 
This is doubtless the Arabian representative of the Somali 
I. umbrosa ; but it is a far prettier insect.
