Show 1899.] FROM BRITISH EAST AFRICA. 973 form of P. charina. I am quite sure that all collectors of South- African species will dissent from his last suggestion, because the wet, intermediate, and dry phases of P. charina are well known, and (apart from size) can readily be distinguished from P. simana by the uniform character of their upper surface at all seasons, and by the absence of the black veins on the upper surface and the black discal spot on the under surface of the male primaries. We do not possess the wet phase of P. gerda, in which the outer border attains to a width of 4 millimetres; but even the intermediate phase has a wider border than the wet phase of P. simana; and in all the specimens now received the grey at the base of the primaries is rather more diffused and the black veins are obliterated almost to the outer margin, bringing the species nearer to P. charina excepting for the black discal spot of the male and the absence of the dense speckling which Characterizes the dry phase of the Natal species; the primaries in P. gerda are somewhat shorter, and therefore less acutely triangular, than those of P. simana. Before leaving Pinacopteryx it is perhaps as well to point out that " Ixias venatus" proves to be a female of a species undoubtedly referable to this genus, and apparently most nearly related to P. liliana ; it certainly has nothing to do with Belenois. 54. HERP^ENIA MELANARGE, var. ITERATA Butl. 2 , Kitwi, 18th January, 1899. " Dark yellow ova " (R. C). 55. PAPILIO ANTHEUS, var. UTUBA Hamps. Tana River, 3800 feet, 3rd January, 1899. " This, a poor specimen rather, is one of only two seen here in as many days " (R. C). 56. PAPILIO NIREUS Linn. 2, Undulating plains N. of Tana River, 4200 feet, 14th January, 1899. " By no means plentiful; the second or third only I have seen"(cR. C). H E S P E R I I D T E. 57. SARANGESA ELIMINATA Holl. E. of Athi R., some 4300 feet alt., Kitwi, 18th December, 1898. " Undulating uplands, timbered with thorny scrub and very dry. This is, I think, an insect very familiar to me in British Central Africa." Mr. Crawshay obtained examples of this species at Machako's, in British East Africa, but not in Nyasa-land; he is probably thinking of S. synestalmenus. 58. ERETIS DJJELCELCE Wllgr.
