LYC^NIDiE. 227 



second nervules originating at some distance apart, before extremity of 

 discoidal cell, — the 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 ; 

 Idnd-ivings with very short discoidal cell ; subcostal nervure branched 

 considerably before middle. Legs short, scaly, not hairy ; tibiee very 

 much shorter than femora, and without terminal spurs ; fore-legs alike, 

 in hoth sexes, those of $ having the tarsi distinctli/ fivc-jointcd and with 

 a pair of terminal curved claics. 



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 TJiyra, 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 of Lachiiocnemci, and apparently also Deloneura, both endemic South- 

 African genera, I do not know of any other form of Lycccnidcc in which 

 the fore-tarsi are equally developed in both sexes, — a feature indicative 

 of approach to the Pierinoi in the family Pcqnlionidoi. 



Wallengren created the genus for the reception of his Basuta and 

 Linne's Protumnus. To these I have added a third, A. hrachycera, 

 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. hrachycera 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. Protummis 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. Irachycera 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.
