The agricultural and forest products of British West Africa

[1]Hinchley Hart, in Cacao, 1892, pp. 48-52, discusses the three varieties mentioned here, and shows that intermediate forms exist which connect all three. The Forastero class includes all the cocoas which have thick skins and large pods with rather flat beans.

[2]S. singularis, a nearly allied insect, is common in certain localities and does similar damage.

[3]Cf. Bull. Ent. Res., vol. i. (1911), p. 83; Bull. Imp. Inst., vol. viii. (1910), p. 150; vol. xiv. (1916), p. 174; vol. xviii. (1920), p. 319.

[4]This has since been identified with Gelechia gossypiella, Sanders, an insect which subsequently effected such enormous damage in Egypt.

[5]These names are substituted for Bauchi and Nupe in the old system.

[7]Ibid., p. 209.

[8]Included in Southern Nigeria exports.

[9]Including copal resin.

[10]Including dressed skins.

[11]Identical with what is termed E. biplaga at Ibadan, but probably a local form of E. insulana.

[12]For the most recent information respecting cotton cultivation here and elsewhere in West Africa, Professor Dunstan’s Reports to the Brussels Congress of Tropical Agriculture (1910) should be consulted.

[13]Since named S. guineensis var. robustum, Stapf.
