Larvae and Pupae of South African Rhopalocera. 51 
and before I left Umzinto, at the end of the month, every 
one I had was a butterfly, nine in number, and all perfect, 
except for a slight malformation in the wing of one ¢. 
3. Charaxes guderiana, Dew 
(Plate IX, figs. 3a, 30, 3c.) 
The remarkable dissimilarity of the sexes is the most 
striking feature in this species; as the 2 could apparently 
be classed as a small species belonging to the saturnus 
group, whereas the @ is like a glorified ethalion. I was 
unacquainted with the ?, though I had taken one or two 
specimens of the ¢ at Umtali (Rhodesia), in August 1908, 
when one hot sunny morning, in September, up the 
“Water Valley,” near Macequece (a Portuguese village 
“over the frontier,” where I was staying), Bersa and I 
simultaneously caught sight of a tawny-brown Charazes 
flying rapidly from one plant to another on the hill-side, 
evidently with a view to finding the proper food-plant, 
whereon to oviposite; so we stood quite still and watched 
her, and it was not long before, having selected the sapling 
of a kind of Acacia (Brachystegia appendiculata), she 
paused, and apparently laid an egg, then flew right away 
out of sight. But there was her egg, right enough, a 
bright green, unmistakable Charaxes ovum; and we were 
soon searching all the similar plants growing on that hill- 
side. Neither was it long before Bersa exclaimed, “ Here 
isalarva!” And there, sure enough, wasa full-fed Charaxes 
larva—quite unlike any we had ever seen before. The 
distinctive markings were crimson-pink on the irrorated 
green surface, consisting of two central pink dots on the 
fourth segment from the head, in addition to which a 
continuous line of pink splashes, one on each segment, 
ornamented this beautiful caterpillar on either side. We 
soon found some more of all sizes, though they scarcely 
seemed abundant on that hot spring morning (September 8, 
1908). This is the life-history of the green egg, which is 
now a f guderiana in my collection:—Hatched out on 
September 13, exactly like any other young Charazes 
larva to look at, of adull ochreous colour, with dark-brown, 
almost black head and tail. First moult satisfactorily 
effected on the morning of September 18. For the second 
time, again in the early morning, on September 22, head 
still dark brown in colour; but, while in this skin,
