1894.] FROM BRITISH EAST APEICA. 575 



salmon, sometimes extending beyond the subapical irregular black 

 band ; under surface nearly as in T. phiUipsii, 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, New^ in 

 forest ; shores of Lake Baringo ; Njempo. 



This is evidently an abundant species. 



93 a. Teeacolus citreus. 



Teracolus dtreus, Butler, P. Z. S. 1876, p. 162. n. 120. 



Kinani, in the afternoon ; also probably Sabaki Valley. 



This differs from T. syrtimis 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 relation- 

 ship 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.

r{ , Thagana, woods beside Ukikuya ; 2 > 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.

Allied to T. theogone ; the male above with the patch upon the 

 black apical area orauge-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 iU-defined unequal spots on third median and 

 radial veins (recalling the marking of female T. Mppocrene), and a 

 marginal series of hastate black spots, almost confluent : body 

 normal. Primaries below white, the costa, apex, outer margin, and
