November 1963)NEWAFRICAN BUTTERFLIESByR.H. CARCASSONYPTHIMA RHODESIANACarcasson (Coryndon Mem.Mus.Oc.Pap. No.7, 1961)(Satyridae, Satyrinae)Several more specimens of this species were collected recentlyin the Mpanda district of western Tanganyika by Mr.J. Kielland ofOldeani, Tanganyika. They belong to the wet season form and areconsiderably darker and brighter than the Holotype. This smallseries includes a specimen of the hitherto unknown female which isdescribed below.FEMALEWings more rounded than male. Head, body and legs as in Holotype,but a little darker.Upperside.Ground colour darker and glossier than in Holotype, with a faintcoppery tinge in some lights. Outer ring enclosing ocellus of fore-wing very distinct, pointed towards tornus, reaching cellule lb.Area enclosed by outer ring somewhat paler than remainder of wing.Distal edge of outer ring parallel with outer margin. Dark submar-ginal and marginal lines of hindwing better defined than in Holotype.A faint, dark evenly curved medial line from vein 2 to vein 6 ofhindwing.67New African ButterfliesUndersideSimilar to Holotype, but brown irrorations darker and moredistinct; proximal and lower portions of outer ring enclosing ocellus,clearly visible. Medial line of hindwing more distinct than above,somewhat bent at vein 5 and continued from inner margin to costa at apoint 2/3 from base.

Uniform sepia (R). A submarginal series of interner-vular hazel (R) spots with diffuse edges, particularly well developedin cellules 3 and 4, reduced to a few red brown scales in 2,5 and 6,sometimes enclosing a small black ocellus with a single white pupilin cellules 2 and 3.Underside.Forewinq.

Blackish grey apical area and blackish grey band separatingorange basal area from distal hyaline area more sharply defined thanin other races and showing greater contrast with adjacent orange andhyaline areas. Black dots in discoidal cell, at base of cellule 2,near base of cellule lb and near centre of lb with sharp edges.Hindwinq. Entirely orange brown, the hyaline marginal band ofother races being reduced to a very narrow, sharply defined blackterminal line. Dark suffusion at base almost absent.

Basal area of forewing brighter orange than in other races.Holotvpe~. Wanzizi, Mpanda District, Western Tanganyika,6-X-l963, J. Kielland, to be deposited in British Museum (Nat.Hist.).One Paratvpe ~, same data as above, in Coryndon Museum, Nairobi.This interesting new subspecies has so far been taken only inrelic forests of the Mpanda District, some 350 miles south of thenearest recorded locality for the Uganda race and some 500 miles westof the nearest recorded locality for the nominate race (Morogoro).A.cerasa cerasa may well turn up in less distant localities such asthe Iringa, Mbeya and Njombe districts, but even so would appear tobe isolated from the habitat of kiellandi by the central Tanganyikaplain, in the same way as the range of cerita is isolated from thatof kiellandi by the low-lying Malagarasi basin.APHNAEUS FLAVESCENS Stempffer, WILLIAMSI ssp. novo(Lycaenidae, Aphnaeinae)MALEUppers ide Differs from fresh specimens of the nominate race in thebluer, less greenish tinge of the light markins, in having narrower,less conspicuous pale abdominal rings, and in the presence of orangescales and cilia near the tornus of the hindwing.Underside Differs from nominate race in having much thicker darkrings surrounding the silver spots, and in the presence of a large,bright orange spot near the tornus of the hindwing. There are alsodifferences in the arrangement of the silver spots. The spots nearthe base of cellules 5 and 6 of the forewing are in line in williamsi,their axis being parallel to that of the large spot at the end of thediscoidal cell, whereas in flavescens the spot in cellule 5 isstrongly displaced towards the base. The same difference appliesexactly to the proximal spots in cellules 5 and 6 of the hindwing.FEMALEAs above, but forewing apex slightly more rounded, blue areasabove somewhat reduced and a little darker.70J.E.Afr.Nat.Hist.Soc.

The author has had theopportunity of examining a perfect specimen of the nominate racerecently collected at Chintechi by Mr. D.
