submargiual series very distinct (in one specimen larger than in the 

 other) and of equal size throughout ; no spot beneath basi-cellukr one. 

 Hind-winij : a distinct basi-cellular spot ; median band resembling that 

 of Diomus, Hopff., but not curved, more oblique, more macular (the 

 crossing nervules forming strongly-marked interruptions) ; submarginal 

 scries 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. Undek side. — 

 Hind-iving and costal and apical border of fore-wing glossy yelloiuish- 

 hroion; all spots very distinct; hind-wing ivith median hand not so 

 macular as on iip)per side, hut continuous from costa to suhmedian nervure, 

 and ivith a suh-hasal curved series of foiir conspicuous spots. Fore-wing : 

 an elongate small whitish spot immediately below discoidal cell near 

 base (lollowed in one specimen by a second similar spot) ; four upper 

 spots of suhmarginal series much larger and more elongated longitudi- 

 nally than on upper side. Hind-tving : a white spot at base ; first and 

 second spots of sub-basal row lather 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 chielly 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 two examples have come under my notice ; 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.
