Show 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 Otiembora and Humbe respectively) 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 two 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 bar1. 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. 12. ACRCEA ACARA, Hewits. 8. Acrcea acara, Hewits. Exot. Butt. iii. pi. viii. ff. 19, 20 (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, where 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. 13. ACBJEA ENCEDON (Linn.). Papilio encedon, Linn. Mus. Lud. Ulr. Reg. p. 244. n. 63 (1764). Humbe (October). Six male and one female examples. These specimens are all of the typical dull-rufous form, none exhibiting any tendency to the pale colouring of the var. lycia, Fabr. 1 Vide infra, p. 73, for an exactly corresponding instance in A. rahira. |
