PSEUDATHYMA NEPTIDINA Karsch, JACKSONI . ssp, nov. [Figs. 1 & 2) 

Differs from the nominate race in the much greater development of 
the white discal markings in both wings above and below, in the absence 
of dark nervular streaks in the white markings of the forewing and in 
the reduction of the white streak in the fw cell. The sexes are simi- 
lar, the 9 being larger and more rounded. 

This new subspecies was recently discovered in the Kakamega Forest 
of western Kenya by Mr, T.H.E. Jackson, the well known lepidopterist 
and small series of both sexes were secured by him and by the author. 
It is astonishing that such a conspicuous insect should have been over- 
looked for so long in a well collected area such as the Kakamega Forest, 
and this may be due to it being a surprisingly accurate mimic of Neptis 
striqata Aurivillius, 

The nominate race is known from the Cameroons and from the Congo. 
The only available East African record, other than the Kakamega speci- 
mens, is a of from the Bwamba Forest, Toro , W. Uganda, which agrees very 
well with the figure of the type in Aurivillius, "Rhopalocera 
Aethiopica", 1898.

Dr. Ansorge in 1909 in the "Nandi country", Kenya. 


Romaleosoma Sarcoptera Butler, Lep.Exot . : 81, (1871) 

Euphaedra cyparissa Cramer, var. sarcoptera (Butler) 
Aurivillius, Rhop. Aethiop. : 189, (1898) 

Although treated as a "variety" of N. cyparissa (Cramer) by 
Aurivillius in "Rhopalocera Aethiopica" and again in A. Seitz, "Macro- 
lepidoptera of the World", Vol, XIII, 1925, p. 186, it should be 
regarded as a distinct species, as its pale subapical patch differs 
consistently in shape from that of N. cyparissa ; this feature would be 
unlikely to be so generally associated with the diagnostic character 
of sarcoptera (red patch at base of fw below), if sarcoptera were a 
mere form of cyparissa . The distribution of N. sarcoptera is heavy 
forest from Dahomey and Ashanti to the Congo, with an isolated race in 
western Tanganyika, described below. 


New Lepidoptera from East Africa 

NAJAS SARCOPTERA (Butler), NIPPONICORUM ssp, nov. (Fig, 4) 

Differs from the nominate race in being larger in both sexes and 
in having a more golden, less green ground colour. The sexes are simi- 
lar, but the 5 is somewhat larger than the c?, more rounded, and has 
less green, particularly in the fw above. 
Measurements : <?, fw, base to apex, 40 mm

Province, Tanganyika, V-1964, Kyoto University African Primate

The forest relics near the eastern shore of Lake Tanganyika 
appear to be inhabited by a surprising mixture of western and eastern 
elements and this is another member of this strange mixed fauna to be 
discovered by the Japanese expedition. See : J.E.Afr.Nat.Hist.Soc .

Differs from other species of the genus in the straight, somewhat 
concave outer margin of the fw, in the rounded hw and in the presence 
of a well developed precostal spur; this species may be wrongly placed 
in Psilocerea . but it would be unwise to erect a new genus to accommo- 
date it without knowledge of the 5 and until the African Ennominae 
have been more adequately studied.
