SOUTH-AFRICAN BUTTEEFLIES. 
Larva. — Ground-colour yellow ; a median dorsal green stripe, and ! 
some narrower ones on each side, from head to tail. Both head and ' 
tail forked. About two inches long." — J. H. Bowhcr's description of 
two specimens found at Northdene, near Pinetown, Natal, feeding on i 
" Eibbon grass," May 1885. 
Pupa. — Bright grass-green throughout, semi-transparent, surface ! 
like shining wax. No markings of any kind ; rather paler on wing- 
covers. Length, 10 lines. Thick and rounded, especially the abdo- 
men, which is dorsally globose and very strongly convex. The main 
dorsal prominence highly ridged and rather acute. Head blunted, not 
bifid, but with two minute pointed tubercles on eye-covers. 
I received the pupa here described on 2 2d May 1885, from Colonel I 
Bowker, "vvlio wrote that it was developed from one of the two larvae above • 
mentioned. It was suspended by a well-developed caudal stalk to a small but 
dense silken web on the under side of a leaf of broad ribbed grass. The imago, I ■ 
a fine $ of M. diversa, appeared on May 31st. Colonel Eowker subsequently |l 
sent me a crippled M. diversa produced from the other pupa, which he retained ' 
in Natal. 
This Melanitis seems considerably rarer than M. Leda in Natal. I met 
with only a few examples near D'Urban and Verulam in February 1867; 
their hannts and habits were precisely those of Leda, and they were quite as 
difficult to see when settled among dead leaves and undergrowth in the shade 
of the woods.

Imago. — Heael rather wide, hairy ; eyes large, with a close clothing 
of short hair ; j^^^^^i long, very much flattened laterally, separated but 
not divergent, — the second joint, very long, with a few short appressed 
hairs above and a smooth dense fringe of hair beneath, — the terminal 
joint minute, slender, smooth ; antenncc short, very gradually incrassated. 
Thorax short, pilose, stout. Fore-wings in some species (Z. Europa, 
(Fab.), and allies) produced apically ; costa rather strongly arched ; 
apex rounded ; hind-margin entire or bluntly dentate ; inner margin 
straight ; costal nervure in a good many species moderately or slightly 
swollen at base ; first and second subcostal nervules given off before 
extremity of discoidal cell, not far apart ; discoidal cell of moderate 
length, wide near extremity, closed rather obliquely, the third disco- j 
cellular nervule forming a somewhat acute angle at junction with third ;
