acts as an aposeme when it is feeding [a note to this effect

a much smaller species [the manica* Trim.. 9 of etheocles, Cr. |. 



A specimen of the commonest small species [guderiana, Dew.] 



was once caught by a large Asilid fly, just as it was fluttering 



round the bait : this speaks well for the power of the Asilid.

Alcimus alamanus, Walk., $ with the c? of Char, guderiana, 



Dew., Nov. 12, 1 « > 1 7 . The Asilid bears the note " probably 



caught as it was fluttering round bait or on it, but I did not 



actually see it in act." Capt. Carpenter also sent a male of 



the same predaceous fly together with the 3 of Char, achae- 



menes, Feld., captured by it Dec. 13, 1917. Both butterfl'es 



are included in the table on p. exxi. 



Capt. Carpenter not only recognised the mimetic resemblance 



of the manica $ to the ? bohemanni the note "? mimic " 



appears on 4 examples of the former and " ? model" on an 



example of the latter taken with one of them on Nov. 20 — ■ 



but he also noted the resemblance of the females of achaemenes 



and guderiana to both sexes of saturnus, Butl. Examples 



of each female and a male of saturnus, taken Nov. 17, bear 



the note " ( mimetic relation : same spot and time." These 



and other records of the three species on the top of the 



kopje at Lulanguru afford valuable independent testimony 



to the validity of Dr. Marshall's suggestion (ibid., p. 505). 



These captures at Lulanguru in one limited area, of mimetic 



Charaxes and their models among the larger species of the 



same group, are recorded in the tabular statement on p. exxi.

It is probable from Capt. Carpenter's experience that the 



manica ,. of etheocles occurs where bohemanni is abundant 



and its female — more conspicuous than the male — commonly 



seen. Where this large species is scarcer the <3 probably 



becomes a more advantageous model than the more rarely 



seen ', . and manica is replaced by the phaeus, Hew., $ of 



the same species. y To test this conclusion we need from
