4 THE ENTOMOLOGIST. 
Lion’s Head ; a species of Hrebia (EH. Hyperbius) and Leptoneura 
Cassus also flew there. 
I have taken four of the genus Terias in the colony, they all 
seem tolerably numerous near here. The species are T. Rahel, 
var. Desjardinsii, Brigitta, and Pulchella. 
Three species of the genus Danaus inhabit the colony; the 
most abundant being D. Chrysippus, which is to be seen all the year, 
and to be met with in all kinds of localities, gardens, fields, hill- 
sides, and forests. Some of the Acr@as mimic this species, and so 
perfect is the resemblance on the wing that many female Acr@as 
look exactly like very small specimens of D. Chrysippus. The 
female of Diadema Misippus, however, is the most perfect mimic of 
the species in question that I have ever seen. It is exactly the 
same size, the ground colour in most instances the same, in 
others slightly lighter, and it possesses the white spots near the 
apices of the fore-wings, as in D. Chrysippus. A very rare variety of 
D. Chrysippus is occasionally found without the customary white 
apical spots (var. Dorippus), and to make the mimicry perfect there 
is a similar variety ofthe female D. Misippus. The male of D.Misippus 
is utterly different, being a rich black, with, in good specimens, a 
suffusion of purple, and with a purplish violet spot in each wing. 
Specimens of D. Chrysippus are met with in the middle of summer 
that possess partially white hind wings; in one instance I met 
with a specimen identical with the West African form, Alcippus. 
Another Danaus, D. Echeria, is very plentiful in woods, and flies 
with a very graceful flight, very much hke Limenitis Sibylla at 
home. The third species, D. Ochlea (a black and white species), 
is tolerably plentiful, but in my cabinets I find it represented by 
about twenty specimens, all that I have managed to secure in 
this part of the colony. 
The Acreas are a peculiar African family of butterflies; they 
have long and narrow fore wings, and most of their females mimic 
Danaus Chrysippus. A. Horta, though plentiful at Cape Town, is 
“not abundant on the Natal coast; but in the elevated lands, twenty 
miles inland, I have taken it. It has a more lofty flight than the 
others of thisfamily. A. Dice (Querina) Ihavetakentwice; itseems 
very rare. A. Zetes is also a scarce insect, and the same remark 
applies to A. Aganice, which latter insect is the largest of the 
family. A. Violarwm is plentiful at Durban and along the coast 
to the Tugela; it is of a brick-red colour, suffused with orange. 
A. Nohara isa rather local species; its colour is fulvous-yellow, and
