irrorated under-surface differs widely from all those that I 

 have examined in this family. D'Urbania seems more nearly 

 allied to Pentila than to any other Genus of Lycaenida, but 

 is at once recognized by the much longer palpi and short 

 abdomen (wrn'ch latter is elongate in Pentila, and thickened 

 at its extremity).* As frequently happens in cases of this 

 nature, the habits of this Genus tend to support its analogy 

 with the Satyridae, Mr. D'Urban having constantly taken it 

 settling on rocks and large stones, not on flowers, like the 

 great majority of the family.

 Exp. 1 in. 2 lin. 1 in. 6 lin. [p. 401. 



Dark-brown, inclining to fuscous : each wing with a 

 submarginal, curved, transverse row of orange-yellow spots. 



$ . Fore -wing : row of six spots, forming almost a 

 semicircle, extending from subcostal to submedian nervure, 

 sometimes indistinctly marked. Hind-wing : somewhat paler 

 than fore-wing ; only four spots in transverse row, which is 

 not markedly curved, extending from second subcostal to 

 third median nervule. Cilia of both wings conspicuously 

 chequered brown and white. UNDER-SIDE. Fore-wing : 

 before transverse row of spots thinly, beyond it thickly, 

 irrorated with whitish ; row of orange spots increased to a 

 broad macular stripe ; the irrorations immediately succeeding 

 stripe forming a series of acute, rather indistinct lunules. 

 Hind-wing : universally and densely irrorated with whitish ; 

 the position of the transverse row of upper-side faintly 

 indicated by some scarcely distinguishable whitish spots, 

 followed by some indistinct fuscous lunules. Cilia not so 

 conspicuously chequered as above. 



? . Orange spots in both wings enlarged and confluent, 

 forming a broad band, which in fore-wing widens at its 

 lower extremity. Cilia as in $ . UNDER-SIDE. Quite 

 similar to that of $ : orange band of fore-wing paler than 

 on upper-side. 



"November and January; common, sitting on rocks and stones." 

 D'Urban, in litt. 



" Eound in " open " on rocky bills ; easily caught." -J. H. Bowker, in litt. 



This remarkable butterfly seems to be local in its haunts, but not 

 uncommon where found. The orange bands present considerable variation 

 as regards their width, curvature, and the contiguity or confluence of the 

 spots composing them.
