Show 102 MR. R. TRIMEN ON BUTTERFLIES [Jan. 20, 109. PYRGUS SECESSUS, n. sp. (Plate IX. fig. 22, 8 • ) Allied to P. sataspes, Trim. 8 • Exp. al. 11 lin. to 1 inch. Fuscous brown, with small dull white spots ; in submarginal series the spots are minute and obsolescent, except two in hind wing (respectively above and below 2nd median nervule). Fore wing : three discocellular spots, of which the middle one is very small and situated close to subcostal nervure; discal series of spots in number and arrangement as in P. sataspes, but 5th spot largest and more quadrate, while 6th and 7th are much reduced in size. Hind wing : a small suhbasal discocellular spot; median marking reduced to a moderate-sized terminal discocellular spot, with a rather smaller spot immediately below it. U N D E R S I D E . - H i n d wing and apex of fore wing dull yellow-ochreous with a reddish-brown tinge, the former with the median band very dull creamy fin one of the two examples much darker, scarcely distinguishable from basal groundcolour), rather broad, oblique, almost straight, irregularly denticulated externally, and bounded internally by three separate brown marks. Fore wing : middle discocellular spot quite as large as the two others. Hind wing : subbasal cellular spot, and two others above and a little beyond it (in one specimen obsolescent), indicate an irregular subbasal transverse band ; median band externally bounded by dark brown, which gradually shades off into yellow-ochreous ; a submarginal sinuated series of minute paler spots very faintly indicated. Among the more marked distinctions of this form from P. sataspes are (besides the dull tint, straightness, and even width throughout of tbe much broader median band of the underside of the hind wings) the presence in both fore and hind wings of a subbasal discocellular spot, the different relative sizes of the lower spots of the discal series in the fore wings, and the ill-defined, narrow, interrupted (instead of dark, continuous, well-developed) internal border of the median band of the hind wings on the underside. The possession of a subbasal cellular white spot in both fore and hind wings is usual in the genus, but P. sataspes, P. nanus, and the aberrant P. sandaster, Trim., want this feature.
