NEWBUTTERFLIES FROM THE KIGOMA AREA OF WESTERNTANGANYIKAByR.H. CARCASSONA large collection of Lepidoptera from-Kabogo Head, south ofKigoma, on the eastern shore of Lake Tanganyika has been submittedfor identification by Dr. J. Itani and Mr. S. Azuma of the KyotoUniversity Primate Research Expedition.The material examined so far was collected during the years1961, 62 and 63 and a comprehensive account of the Lepidoptera ofKabogo Head will be published when the expedition has completed itsfield work in Africa. In the meantime some general notes on theLepidopterous fauna of the area, together with the description ofsome new forms, would appear desirable.The bulk of the collection has been assembled near a streamwhich runs into Lake Tanganyika between Kigoma and the Kungwe MahareMountains. There is some riverine forest on the banks of the stream,but. the surrounding country is mainly Brachvsteqia woodland. Thealtitude is approximately 800 m. above sea level and the latitudeabout 5. 6' South.The material collected so far is a surprising mixture of easternand western elements as well as including many of the species charac-teristic of Brachvsteqia woodland which also occur in Angola, Katanga,N. Rhodesia and southern Tanganyika.There are also a number of new, very distinct and apparentlyendemic species and subspecies, some of which are described below.The following are some of the more interesting eastern speciesand subspecies which have turned up at Kabogo Head:Charaxes protoclea azota HewitsonCharaxes pvthodorus nesaea Grose-SmithCharaxes brutus natalensis StaudingerPrecis natalica natalica FelderGraphium porthaon HewitsonPapilio ophidicephalus ophidicephalus OberthUrCoeliades seiuncta Mabille & VuillotThere is a large number of species typical of the equatorialforest of the Congo and West Africa; the following have not beenpreviously recorded from any part of East Africa, not even fromUganda, which is very rich in Congo species:Palla publius StaudingerBematistes vestalis conqoensis Le DouxBematistes epiprotea ButlerNOTE: In the following text, the initials K.U.A.P.E. are an abbrevi-ation of "Kyoto University African Primate Expedition".62J.E.Afr.Nat ..Hist.Soc.

A rowof dark brown internervular dots from cellule lb to cellule 6, edgedproximally with whitish scales; a whitish dot at costa halfway frompostmedial band to apex. A submarginal series of internervular darkbrown arrow shaped markings with apex pointing outwards, from cellulelb to apex. Ground colour outside postmedial band, from vein 3 toinner margin darker (Saccardo's umber (R)) than elsewhere.

Someblackish scales outside blackish line in cellules 2 and 3 and adiffuse whitish spot mixed distally with blackish scales outsideblackish line in cellule Ie. A complete, evenly curved series ofblack internervular streaks edged proximally with a few paler scalesfrom vein 8 to vein Ib, followed distally by a parallel series ofsubmarginal blackish arrow-shaped markings, as in forewing.
