V.—Revision of the Lepidopterous Genus Azelina, with 
Descriptions of new Species in the Collection of the British 
Museum. By Artuur G. Butter, F.L.S8., F.Z.8., &e. 
THE genus Azelina was founded in 1857, by M. Guénée, for 
the reception of a number of New-world Geometrites with 
the external aspect of the European genus Odontopera; to 
the latter group he added two African and one Brazilian 
species. He remarks with justice, “Il a beaucoup de rap- 
ports avec mon genre Azelina, et je ne serais pas étonné que, 
par la suite, quand beaucoup de nouvelles espéces se joindront 
4 l'un et A l'autre, la séparation n’en devienne trés-délicate.” 
O. edentaria, which we have from Rio Janeiro, certainly 
might be placed with equal satisfaction in either genus ; how- 
ever, for the present I leave the question of the probable 
identity of these two groups, and proceed, in the first place, to 
criticise the material wrongly placed under Azelina, and, in 
the second place, to enumerate the remaining species. 
The following species are wrongly placed in Azelina by 
Walker and others :— ; 
“Azelina”’ peplaria=Gonodontis peplaria, Hibn., agrees 
far better with Hindropia. 
“Azelina”’ neonaria, Walk., is a Hyperetis close to H. 
nyssaria and nearly allied to Selenia esionaria (= Macaria 
laticincta). i
