)02 MR. R. TRIMEN ON BUTTERFLIES [Jail. 20, 



109. Pyrgus secessus, n. sp. (Plate IX. fig. 22, c? •) 

 Allied to P. sataspes. Trim. 



(S . Exp. al. 1 1 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 

 modprate-sized terminal discocellular spot, with a rather smaller 

 spot immediately below it. Underside. — Hind wing and apex of 

 fore wing dull yellow-ochreous with a reddish-brown tinge, the 

 former with the median band very dull creamy (in one of the two 

 examples much darker, scarcely distinguishable from basal ground- 

 colour), rather broad, oblique, almost straight, irregidarly denticu- 

 lated externally, and hounded internally by three separate brown 

 marks. Fore wing : middle discocellular spot quite as large as the 

 two others. Hind iving : 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 the much broader median band of the underside of the hind 

 wings) the presence in both fore and hind wings of a subbasal disco- 

 cellular spot, the different relative sizes of the lower spots of the 

 discal series in the fore wings, and the ill-defined, narrow, inter- 

 rupted (instead of dark, continuous, well-developed) internal border 

 of the median band of the hind wings ou 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.
