The two females agree with their respective mates, the specimen from above Sarmento having the submarginal fuscous on the upper-side of both wings completely broken up into spots, and the underside more reddish and much less distinctly marked than in the one from Mineni Valley. The South-African Museum has for many years been in possession of a single imperfect male of this species, received with a few other Butterflies collected on the Zambesi by (I was informed) the Eev. H . Waller. It agrees pretty closely with the Mineni Valley male above noted, but has the silvery-white stripe on the underside of the hind wings still broader. The male expands 2 in. 9-11 lin. ; the female 3 in. 4 lin. C. lasti is the Eastern representative of C. cynthia, Butl. ( $ C. lysianassa, Westw.), a widely distributed West-African species recorded from Ashanti, Cameroons, and Angola. It is distinguished by its smaller size, by the great expansion of the fulvous and the consequent reduction of the fuscous colouring on the upperside, and by the great attenuation and partial obliteration of the markings of the underside. Mr. Last discovered this Butterfly at Mombasa, and it is interesting to find it extending so far to the south as the Manica Country. Mr. Selous notes that both the first and second of the males above mentioned were captured while drinking at the edge of water, while the female in the Mineni Valley was settled, with wings expanded, on the leaves of a thorn-tree. 61.

Monteiro, Delat^oa Bay, &c. frontisp. fig. 1 (1891). A fine female of this handsome species is noted as being the only one seen ; it was taken at the Lusika Eiver on 13th April, frequenting the same tree on which specimens of C. castor were found. Since the publication of m y notes on this species (S.-Afr. Butt. iii. p. 388, 1889), C. azota has been found in some numbers near Delagoa Bay by the Eev. H . Junod, and a series of eight males and three females has been acquired from him for the South- African Museum. In the male the " tails " of the hind wings are represented only by two short acute dentations; but in the female not only is the dentation on the 1st median nervule considerably more produced, but there is a distinct tail on the 3rd median nervule. This tail varies both in length and form, being pointed at the tip in two specimens and rounded in two others; in one of the latter (Mr. Selous's example) it is even inclined to a spatulate form. |
