VII. On Butterflies recently received by Mr. Swanzy from 

 West Africa. By A. G. Butler, F.L.S., &c. 



[Bead 21st February, 1870.] 



I HAVE derived much pleasure from the examination of a 

 small collection of Butterflies recently sent from West 

 Africa by Mr. Ussher to my friend Mr. Andrew Swanzy. 



Amongst the interesting species in this collection may 

 be mentioned a very fine example of Papilio Zalmoxis of 

 Hewitson, and two well-preserved specimens of Harma 

 Jodutta of Westwood. There are also five species which 

 appear to be new, belonging to the genera laera, Aterica, 

 Romaleosoma, Philognoma, and Mycalesis ; the first two 

 species will require further comparison, the others I 

 describe as follows. 



Genus Romaleosoma, Blanchard. 

 Romaleosoma Lahuma, n. sp. 



? . Wings above, olive-brown : the front-wings tipped 

 with white, and with a narrow, oblique, subapical ochreous 

 band, beginning upon the costa, and terminating upon 

 the third median branch ; the costa deep blue ; a narrow 

 squamose blue stria beginning upon the inner margin, 

 near the anal angle, and terminating just below the first 

 median branch : hind-wings with a discal blue streak, 

 running parallel to the outer margin, beginning upon 

 the abdominal margin and tapering to the first subcostal 

 branch. 



Wings below, golden-green : front- wings tipped with 

 white ; a pale whitish oblique bar, answering to the ochre- 

 ous band of the upper surface; black discoidal spots and 

 submarginal chain-band, as in B. Eupalus : hind-wings 

 with a broad angulate whitish band beyond the cell, be- 

 ginning upon the costa and tapering to the third median 

 branch; otherwise as in B. Eupalus. 



Expanse of wings, 3 inches, 9 lines. 



Hab. — Gold Coast. Coll. Swanzy. 



Allied to B. Eupalus of Fabricius, and B. Harpalyce 

 of Cramer, but agreeing with neither.
