134 LLOYD'S NATURAL HISTORY. 



figured in Grose Smith and Kirby's " Rhopalocera Exotica," 

 and several additional species have appeared in the works of 

 other authors. In most cases, the wings are rounded and 

 entire, or but slightly scalloped. 



Many of these species are tawny, with broad black borders, 

 and have much resemblance to species of Acrcein, which they 

 evidently mimic. Thus, the species of Mimacrcea, Butler, 

 expand considerably over two inches across the wings, which 

 are yellowish or reddish beneath, with radiating black and 

 yellowish streaks on the outer half of the wings, and with 

 numerous black spots towards the base of the hind-wings. 



The typical species of the genus Liptena, Westwood, are 

 smaller than Mimacrcea, not attaining two inches in expanse of 

 wing. They are red or tawny, with broad black borders, and a 

 transverse white or yellow transverse fascia towards the tip of 

 the fore-wings, while the border of the hind-wings is spotted 

 with white beneath, both above and below. On the under side, 

 they are reddish or yellowish, with transverse black and white 

 markings towards the costa of all the wings. These Butterflies 

 appear to mimic the common African Moths belonging to the 

 genus Atetis, Westwood. 



Other genera with black and red, or black and tawny 

 markings, but containing smaller species, are Pseuderesia, 

 Butler, Alcsna, Boisduval (long included in the Acrccince, not- 

 withstanding its very different appearance), and Durbania, 

 Trimen. 



There are three genera of blue Butterflies of this group, re- 

 placing in Africa the species of Theda, &c., which are so 

 numerous in other parts of the world. They vary in size from 

 an inch and a half to over two inches in expanse. These 

 genera are Phytala and Epitola, Westwood, and Heivitsonia, 

 Kirby. Epitola contains a considerable number of rather dis- 

 cordant species, and will ultimately require sub-dividing. The
