1 84 SOUTH- AFRICAN BUTTERFLIES. 



fifth, and sixth sometimes obsolete ; blue usually extending as far as 

 discal row ; liind-marginal blackish border linear, usually obsolete or 

 fragmentary below third median nervule. Cilia only slightly mixed 

 with whitish between nervules. Under side. — Hincl-wiiuj, and modc- 

 ratehj-ioide costal, apical, ami hind-marginal border of forc-iving, dull 

 g^'cyisli ochrcy-ycllou\ without or with very faint markings. Fore-wing : 

 all the spots as in Thyshc, those above median nervure and its third 

 nervule similarly centred with silvery ; submarginal macular streak 

 indistinct, ferruginous, with a broad blackish inferior termination above 

 submedian nervure ; hind-marginal border unvaried by any crossing 

 streaks. Hind-iving : markings either absent altogether or very faintly 

 exhibited in outlines indicating the characteristic darker clouding and 

 silvery lituras of Thyshc. 



$ Blue very much pcdcr and duller, and not extending to middle 

 in either wing ; spots of discal row larger, especially in hind-wing, 

 where all six are well developed ; cilia more whitish between nervules. 

 Under side. — As in ^ ; but in hind-wing the darker cloudings and 

 silvery litura3 more apparent — especially the latter, which are faintly 

 metallic. 



Hind-margins not so dentate as in Thyshe ; the angulation in fore- 

 wing blunter, not so prominent. 



It is doubtful wlietlier tljis form is really more than a variety of Tlvjshe, 

 especially as the only 5 s (two) I have seen, and also one $ taken near Malmes- 

 bury and another at Port Nolloth, in the Cape Colony, indicate with some clear- 

 ness on the under side of the hind-wings the characteristic markings of that 

 species. At the same time, the smaller size, blunter outline of wings, usually 

 more extended silvery-blue in the $ , and (even in the examples just specified) 

 obscureness of the under side, render Osbecld easily recognised. The character 

 last named approximates this form to Pyroeis, Trim., in which, however, the 

 spots indicated are rounded. 



Mr. Aurivillius sent me for inspection the type of this species from the 

 Stockholm Museum; it is a ^. He notes (Joe. cit.) that it bore the un- 

 doubtedly wrong label of "India orientalis." It agreed very nearly with the 

 (J mentioned beneath as having been taken by myself at Elaauwberg. 



I took a $ and a very small $ (exp. only 10 lines) at Port Xolloth in 

 August 1873, and did not meet with the form again until September 1879, 

 when Colonel Bowker and myself each captured a $ near Malmesbury. At 

 Blaauwberg, on the coast of the Cape District, I met with a fine pair in the 

 following January ; and Mr. L. Peringuey gave me four similar ^ s which he 

 captured rather farther to the north, at Paternoster Bay, Malmesbury District. 

 Thus far, therefore, it would appear to be a form peculiar to the "Western 

 Coast Districts of the Cape Colony. There is nothing in its habits to distin- 

 fruish it from its nearest allies.
