i submarginal series very distinct (in one specimen larger than in the 
i other) and of equal size throughout ; no spot beneath basi-cellular one. 
I Hind-wing : a distinct basi-cellular spot ; median band resembling that 
; of Diomus, Hopff., but not curved, more oblique, more macular (the 
I crossing nervules forming strongly-marked interruptions) ; suhmarginal 
series of spots more complete than in any of the allied forms, there being 
a series of three (rather smaller than the rest) somewhat obliquely placed 
between first subcostal and third median nervules. Under side. — 
;j Rind-wing and costal and apical lorder of fore-wing glossy yellowish- 
: hrown ; all spots very distinct; hind-wing with median hand not so 
macular as on upper side, hut continuous from costa to suhmedian nervure, 
and with a suh-hasal curved series of four conspicuous spots. Fore-wing : 
1 an elongate small whitish spot immediately below discoidal cell near 
i base (followed in one specimen by a second similar spot) ; four upper 
spots of submarginal series much larger and more elongated longitudi- 
nally than on upper side. Hind-wing : a white spot at base ; first and 
second spots of sub-basal row rather large and pyriform, third spot 
very small, fourth spot narrow and elongate, adjoining greyish-white 
of inner-marginal fold ; seven spots in median band (which is irregular 
in outline on both edges), the two lowest spots almost touching the 
fourth spot in sub-basal series ; spots of irregular submarginal row 
considerably larger and more elongated than on upper side. 
This is a very distinct little species, at once to be recognised by 
the thickly maculated under side of the hind-wings, owing chiefly to the 
unusual separation and definition of the sub-basal spots, and (to a less 
degree) of those forming the median band, and to the number and large 
size of the spots of the submarginal series. 
Only t\YO examples have come under my iiotice ; one sent to me from the 
Transvaal by Mr. T. Ayres in 1878, and the other in a collection made by the 
same naturalist in that country, and acquired by the South- African Museum in 
the following year.
