As far as can be ascertained, but few opportunities have 

 occurred for a study of the Lepidopterous insects found in 

 the ultra-forest zone of the West African region north of 

 the equator. This is probably accounted for by the fact 

 that the forest zone is so rich in species, in comparison 

 with the drier tracts, that more attention has been generally 

 given to the former. The genus with which this paper 

 deals is almost entirely a dry country or desert one, and 

 is but poorly represented within the forest limits. Dr. 

 Aurivillius in Seitz, " Macrolepidoptera of the World," 

 vol. xiii, supplies a general account of the distribution of 

 the known species, and the following list gives the actual 

 records in the West African region to as recent a date 

 as at present available. The present paper adds some 

 further species to the list. 



Species in Seitz, " Macrolep." : — 



T. chrysonome Klug. Bornu (N. Nigeria). 



T. doubledayi Hpff. Sierra Leone. 



T. amelia Lucas. Senegal.

Through the courtesy of Capt. Armitage, the Chief 

 Commissioner, I have recently had the opportunity of 

 examining several small collections made by himself in 

 the Northern Territories of the Gold Coast, a country 

 similarly conditioned to parts of Upper Senegal and 

 Northern Nigeria, where thick bush growth does not exist, 

 except in proximity of the large rivers, and where the
