72 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, 



amba-Oamatako (January), Six male and six female examples 

 (four males and two females belonging to the var. lygus, Druce). 



The male specimens are more warmly tinted above than the more 

 southern examples, and this is especially the case in two (from 

 Otierabora and Humbe respectiA^ely) of the var. lygus, where the 

 hind wing and the inner-marginal border of the fore wings were (in 

 July 1888) of an exquisite pink with a slight primrose bloom or 

 gloss. The variety was also met with at Ehanda. 



In two males of the variety (and also in a typical male from 

 Bechuana-land) two additional black spots, corresponding with those 

 usually possessed by the allied A. natalica, Boisd,, occur near the 

 hind margin between the second median nervule and the submedian 

 nervure ; the lower of these tw^o spots is faintly represented in two 

 females of the variety. In one of the typical males from Otiembara 

 an aberration in marking occurs in both fore wings, on both upper 

 and under sides, in the shape of a straight longitudinal blackish 

 streak uniting lower part of terminal discocellular spot with the 4th 

 spot of the subapical macular bar \ 



In three females of the typical form the white abdominal spots of 

 the posterior segments are so enlarged as to be coalescent, making 

 the posterior half of the abdomen as white as in the male,

 (1865). 



Ehanda (August-September). One female specimen. 



This solitary example is an aberration, presenting in the fore 

 wings a wide suffusion of black, which includes the subapical black 

 bar, the whole of the discoidal cell (except a small space between 

 the basal and middle cellular black spots), and the costal border to 

 the base ; the basal area below the cell is also fuscous as far as the 

 origin of the first median nervule, and the two inferior discal black 

 spots are enlarged and somewhat diffused. The hind wings are 

 more rufous than usual, and without dorsal white clouding ; their 

 basal markings are remarkably distinct, and the hind-marginal black 

 border is well defined and completely encloses the series of ochreous 

 spots. On the underside the same peculiarities prevail in the fore 

 wings, w^here also the subbasal black spots below the median 

 nervure are much enlarged ; while the ground of the hind wings is 

 almost wholly pinkish red, with very little white scaling on the 

 disk,

 Humbe (October). Six male and one female examples. 

 These specimens are all of the typical dull-rufous form, none ex- 

 hibiting any tendency to the pale colouring of the var. ii/cia, Fabr.
