Show 1894.] FROM BRITISH EAST AFRICA. 575 salmon, sometimes extending beyond the subapical irregular black band; under surface nearly as in T. phillipsii, but more strongly tinted with yellow, buff, and pink, and with the discal brown markings larger and better defined. Expanse of wings 42-43 millim. Ngatana; platform on Kikuyu escarpment, Kedong, Newa in forest; shores of Lake Baringo ; Njempo. This is evidently an abundant species. 93 a. TERACOLUS CITREUS. Teracolus citreus, Butler, P. Z. S. 1876, p. 162. n. 120. Kinani, in the afternoon; also probably Sabaki Valley. This differs from T. syrtinus in its usually inferior size, less black-bordered primaries, and the pink colouring on the under surface of the secondaries. It probably bears the same relationship to T. syrtinus that T. eucharis of India does to T. titea. Unfortunately only one example has an indication of exact locality, so that it is impossible to tell whether the two types occur together; but with our present knowledge of the variability of species I hesitate to consider them distinct. 94. TERACOLUS NOUNA. Anthocharis nouna, Lucas, Expl. Alg., Zool. iii. p. 350. n. 14, pi. i. fig. 2 (1845). 3 , Machakos, two damaged specimens. 95. TERACOLUS THEOGONE ? Anthocharis theogone, Boisduval, Sp. Gen. Lep. i. p. 575. n. 23 (1836). 3, Thagana, woods beside Lkikuya; $ , park-land between Thegu and Ukikuya. Only one damaged pair was obtained. The male is almost exactly like typical T. theogone, but has larger marginal spots to the secondaries : the female has no trace of the inner marginal broad black band to the primaries, and therefore nearly approaches that sex of T. epigone; the under surface of the secondaries also is pink, not yellowish. Possibly this is a species between T. theogone and T. epigone; but the two specimens are not good enough to describe. 96. T E R A C O L U S PYRRHOPTERUS,sp.n. (Plate XXXVI.figs. 8,9.) Allied to T. theogone; the male above with the patch upon the black apical area orange-vermilion, as in the female of that species; the costal margin black quite to the base; a broad truncated black streak on internal area from base to second third of wing : secondaries with a similar though less regular costal streak • two ill-defined unequal spots on third median and radial veins (recalling the marking of female T. hippocrene), and a marginal series of hastate black spots, almost confluent: body normal. Primaries below white, the costa, apex, outer margin, and |
