pale yellow band, divided by the nervures, which are scarcely seen ; 

 posterior wiug with a loug tail, deutated and traversed by a sub- 

 marginal series of five green-yellow spots, the two spots nearest the 

 base of the tails large. 



Under-side : as above, except that it is paler, with the base of the 

 anterior wing and the inner margin of the posterior wing ochreous- 

 yellow ; that the posterior wing has a black spot, bordered above with 

 carmine, near the costal margin above the central band ; that there is 

 a carmine spot, marked with black, at the end of the cell, and two 

 linear carmine spots between it and the inner margin ; and that it is 

 crossed by a series of large black spots beyond the midde, and by a 

 sub-marginal series of linear black spots irrorated with lilac-white. 



Expan. 3i inches. Hab : Gold Coast. 



Nearly allied to P. Kirlyi, and, like it, remarkably different from 

 any other African butterfly which we have seen before. It was taken 

 by Mr. Henry Rogers, on his way to St. Paulo de Loanda, where he 

 has gone on a collecting expedition. Mr. Sogers, making a long and 

 tedious voyage profitable, contrived to collect and send home nearly 

 700 insects taken during his passage. 



DiADEMA Chapmajs'i, sp. n. 



Upper-side : rufous-brown, with the margins broadly dark brown ; 

 the nervures black, the fringe marked by small white spots between 

 the nervures. 



Under-side : as above, except that the base of the anterior wiug 

 and the costal margin of the posterior wing are brightly ferruginous ; 

 that both wings have a sub-marginal series of very minute spots, in 

 pairs ; and that the anterior wing has a large bifid white spot between 

 the median nervures. 



Expan. 3to inch. Hab : Calabar. 



I have given myself the pleasure of naming this species after Mr. 

 Chapman, of Glasgow, an ardent admirer of the Lepidoptera, who has 

 kindly added it to my collection. It is quite unlike any other species.
