second nervules originating at some distance apart, before extremity of 
discoidal cell, — tlie third and fourth together about midway between 
extremity of cell and apex, — the fourth terminating at apex ; in the ^, 
an ill-defined smooth patch over the median nervules at their origin ; 
hind-wings with very short discoidal cell ; subcostal nervure branched 
considerably before middle. Zegs short, scaly, not hairy ; tibia3 very 
much shorter than femora, and without terminal spurs ; fore-legs alike 
in hoth sexes, those of $ having the tarsi distinctly five-jointed and with 
a pair of terminal curved claws. 
Abdomen long and thick, — in $ bulky. 
The three known species of this singular genus, whicli is confined 
to South Africa, bear much resemblance to the more robust members 
of the section of the genus Zeritis represented by Thyrct, Linn., but the 
characters above given — especially the full development of the fore- 
tarsi in the $ — amply serve to distinguish Arrugia. With the excep- 
tion oi Lackmcnema, and apparently also JDeloneura, both endemic South- 
African genera, I do not know of any other form of Lyccenidm in which 
the fore-tarsi are equally developed in both sexes, — a feature indicative 
of approach to the Pierincc in the family Parpilionidce. 
Wallengren created the genus for the reception of his Basuta and 
Linne's Protnmnus. To these I have added a third, A. hrachyeera, 
which, to some extent intermediate between them, is distinguished from 
both by the extreme shortness of the antennae. The colouring of all is 
very dull, and A. hrachyeera is particularly dingy, the paler specimens 
of A. Protumnus only presenting on the upper side a considerable space 
of ochre-yellow. On the under side the tint is mainly a hoary-grey 
varied with darker markings. The sexes of Protumnus and Brachycera 
are much alike, but those of Basuta very different, owing principally 
to the exceptional size and mass of the thorax of the $ and the 
general suffused fuscous-ochreous of his wings, in contrast with the 
moderately robust thorax and darker conspicuously white-spotted wings 
of the 
A. Protumnus is widely distributed over both the Eastern and 
Western Districts of Cape Colony, and has occurred in the Transvaal ; 
while A. Basuta has a large eastern range over Kaffaria, Natal, and 
the Transvaal, but is not known within the limits of the Cape Colony 
except in Basutoland. A. hrachyeera seems to be exceedingly local ; 
it was numerous at Knysna on the southern coast of Cape Colony, but 
elsewhere I know only of its very rare occurrence, and that as a small 
dark variety, at Cape Town. 
I have not met with Basuta in life, but have frequently captured 
Protumnus and Brachycera. The latter both frequent the hottest and 
driest spots, resting on the bare ground after the manner of many 
species , of Zeritis ; they are with difficulty roused, and then only shift 
their position by a very short though rapid flight.
