G, H (1781). Omrora (August) and Omaramba-Oamatako (January). Three male examples. 106. PYRGUS DROMUS, Plotz. Pyrgus dromus, Plotz, Mitt, naturw. Ver. Neu-Vorpomm. u. Riigen, 1884, p. 6. n. 13. Ehanda (August-September). One male example. 107. PYRGUS MAFA, Trim. Pyrgus mafa, Trim. Trans. Ent. Soc. Lond. 1870, p. 386, pi. vi. f. 12. Ehanda (September). One male. The single specimen that I believe is referable to this species is smaller than usual, expanding barely 11 lin. The upperside differs in no respect from ordinary P. mafa, but on the underside of the hind wings the ground-colour is duller and paler, and the subbasal and median white stripes are rather narrower, more widely interrupted (so as to present a more macular appearance), and (in common with the submarginal series of white spots) with much broader and darker brownish-grey edging. 108. PYRGUS DIOMUS, Hopff. Pyrgus diomus, Hopff. Monatsb. Akad. Wissensch. Berl. 1855, p. 643 ; id. Peters, Ueise nach Mossamb., Ins. p. 420, t. xxvii. ff. 9, 10 (1862) \ Ehanda (August-September) and Omaramba-Oamatako (January)- Ten examples ; nine males and one female. The two Ehanda males differ from the rest (and from all other specimens that have come under my notice) in the narrowness of the median white oblique band on the underside of the hind wings, which in one example is not more than half the usual width. 1 I have not seen any specimen that entirely agrees with Hopffer's figure of the underside, the white bands of the underside of the hind wing being in every instance more oblique. The direction of the bands in this figure is intermediate between that found in P. dromus, Plotz, and the decidedly oblique course just referred to. |
