On the road to Begabe’s, kraal a Naja haje was captured , and a 
T arbophis semiannulatus. In the vicinity of Gradhla I shot a black 
mamba ( Dendraspis angusticeps), but damaged it so much that only 
the head and neck were preserved. It was a large specimen, 12 feet 
3 inches in length. 
The only further catches in reptiles were two Homopholis wahl- 
bergi . Undoubtedly snakes will be plentiful in summer time, but, 
in my opinion, this country will be poor in lizards all the year round. 
The soil is too sandy and there are no stony kopjes. 
Amphibians and fishes were not caught. 
Fishing is very difficult in Maputa River so near its mouth, as the 
tidal motion is very strong and the banks are not easily accessible. 
Lake Manyene should prove a good fishing ground. The pans at 
Inguenha and near Grabene contained a good many Kurpers belonging 
to the genus Tilapia. 
My attention was chiefly directed towards the insects. Of these 
the Lepidoptera were better represented than any other order. A 
detailed description of the species caught is given by Mr. Swierstra 
in the preceding article. 
At Inguenha most of the collecting was done in the old mealie 
lands. These were excellent places for small Teracoli and Acraeids. 
In June only one species of tree was in flower, i.e. the Brachylaena 
discolor, belonging to the Compositae, and the specimens of this tree 
were swarming with acraeas, nearly all A. encedon and A. buxtoni. 
C ally dr gas florella was common, Eronia leda rather rare, Melanites 
leda rare, Eurytela dry ope rather rare, Mycalesis perspicua? common. 
At our first visit Pieris spilleri began to appear. Teracolus auxo 
and topha were absent. On our return in the beginning of July these 
two species were very common, whilst nearly all the other species had 
disappeared. 
During our stay at Gfadhla the majority of Eronia cleodora, a good 
many Teracolus regina , T. annae, Acrea oncaea, and Charaxes brutus 
were captured. 
At Lake Manyene the majority of the butterflies were caught. 
On the northern shore of this lake are high banks, thickly wooded. 
On the margin of the forest were three trees absolutely covered with 
the Asclepiad creeeper (Sarcostemma mminalis), which was in full 
flower, and these thousands of flowers — clustered together in a small 
space, free from thorns — offered the best collecting spot imaginable. 
Pieris mesentirba , P. severina, Teracolus eris, T. mutans, T. 
regina, T . ione, T . auxo, T. topha, Callidryas floreila, Precis clelia 
were swarming, a few Papilio demoleus, Ilerpaenia eriphia came 
accidentallv, and once a fine Amauris was seen. The orange-tipped 
Teracoli did not settle on the flowers, but were plentiful in the vicinity 
and mostly alighted on the ground. Quite near to this place three 
Melanites leda and a Charaxes jahlusa were captured. Contrary to 
my expectations this Charaxes settled on the dead flower head of a 
Composite, and the Melanites showed themselves much more in open 
spaces than they generally do. 
Another good collecting ground was found in the lands at Gadlila 
in the neighbourhood of fhe water holes. A few Pedaliaceae 
( Sesamum alatum and indicum ), some Cucurbitaceae, and several 
Hibiscus were flowering, and more specially these last ones attracted 
butterflies, beetles belonging to the Mylabrinae ( Ceroctis warshalli) ,
