115. — Euxanthe tiberius. Smith. Coast hills. This species is never common 

 and is extremely local. It is found only in dense forest. It is a magni- 

 ficent insect. It generally settles on saplings under the shade of large 

 trees, and its flight is rather slow as a rule. 



116. — Charaxes brutus. Cram. Generally distributed. 



117. — Charaxes castor, Cram. Coast district. Taita, Taveta. Not uncommon. 

 The larva feeds on Afzelia caunzensis, which is known to the Swahilis as 

 Bambakofi. The head has four divergent horns and is green, with the 

 horns tipped with red, the outer ones with a yellow stripe on the out- 

 side. The body is green with a yellow spiracular stripe and is covered 

 with small yellow tubercles. It has a rotind greenish-yellow spot with a 

 black centre on the seventh segment, and a similar more irregular spot 

 on the ninth segment, the latter being sometimes obsolete. The pupa is 

 bluish-green with white markings. The egg is spherical with the top 

 slightly concave ; it is yellow with a dark brown ring rovmd the top. 



118. — Charaxes saturnus, Butl. Coast district. Taita, Taveta. Not uncommon 

 in some years. The larva is similar to that of Ch. castor, but has a 

 smoother appearance, and the large dorsal spots have the centre bluish- 

 green instead of black. The pupa has the white markings miich less 

 developed. 



119. — Charaxes hansali, Feld. Taita. Ukambani. I have only taken a few of 

 this rare species. 



120. — Charaxes pollux, Cram. Taita. N. Kikuyu. Not uncommon. The larva 

 is green with a small round riifous spot on the back of the seventh 

 segment, and the tips of the horns are bluish. 



121. — Charaxes tavetensis, Rothschild and Jordan. I have only obtained a 

 single specimen of this rare form which was reared from a larva found 

 at Jilore on the same kind of tree as that of Ch. castor. The larva is 

 green with an indistinct triangular mark on the seventh segment, the 

 apex pointing towards the tail. The pupa is dark green with broad 

 bright yellow spots and bands. 



122.— Charaxes boueti lasti, Smith. I have only taken this species in the Coast 

 district, where I have fovmd it fairly common. It is not quite so active 

 as most species of the genus, and females are not so scarce as in some 

 species, e.g., Ch. etheocles. 



123. — Charaxes azota. Hew. Coast hills. Taveta. This fine species is rather 

 vmcommon. The larva is of the usual Charaxes shape. The colour is 

 green, the head being bordered with brown. It has an orange spiracular 

 stripe, the tubercles being more orange and the green of the body has a 

 somewhat mottled appearance which changes before pupation into dull 

 yellow, with a row of large lateral ill-defined brown spots. The dorsal 

 spot on the seventh segment is large and triangular with the apex 

 pointing backward. It is orange brown. The pupa is pinkish with 

 chocolate brown markings.
