The range of this beautiful butterfly extends from S.E. Africa to S.W. Africa, 

 and north to Teita and Equatorial Africa. It was originally described by Dr. Trimen 

 from the region of Lake N'ganii, but there can be no doubt that T. anax of Grose 

 Smith, and my own T. eliza, described from East Africa, are identical with Dr. 

 Trimen's species from S.W. Africa. It is one of the finest of the purple-tipped 

 section of the genus Teracolus, and both sexes have some purple on the apical area 

 of the primaries. There is not very much diflerence in tlie appearance between the 

 so-called " wet " and " dry " season forms, but in the latter phase the black markings 

 are more restricted and the purple patch in the male is more brilliant and scin- 

 tillating. 



Dr. Trimen in his celebrated work vol. iii. p. 1 13, writes : " Mr. T. Ayres informs 

 me that he met with the species ' in numbers for a very short time in December 

 1875,' among the mountains in the Lydenburg District of the Transvaal, and several 

 examples (including one $ of Var. a.) taken near the junction of the Marico and 

 Limpopo Rivers have reached me from Mr. Selous and Mr. Erikson. Mr. John 

 A. BeU, who in 1862 made me first acquainted with the butterfly, brought down
