222 MR. A. G. BUTLER ON NEW OR RARE LEPIDOPTERA. [Mar. 20, 



nigris, linea interrupta transversali ad angulum ant posticarum 

 continuatis : fascia marginali nigra, anticarum quoque lineas duas 

 undatas (internam vix visam) exhibente. 



Alee maris subtus roseo-aurantiaccp , stria media argentea posticarum 

 regvlari bene expressa, anticarum autem subtriangulari diffusa, 

 fulvo utrinque limitata ; striolis quinque basalibus, fascia submar- 

 ginali undata bene expressa et margine externa fulvis ; punctis 

 tribus lunulatis subapicalibus argenteis diffusis : posticcB punctis 

 sex nigerrimis postmediis, fulvo late cinctis : ulce femince subtus 

 roseo-cinereis, area discali virescente ; fasciis omnibus brunneis ; 

 aliter velut in mare. 



Exp. alar. tine. 1\^-2\^. 



Hah. Malacca {Coll. Boberts). 



This beautiful species is allied to C. bajadeta and C ravana of 

 Moore, but is very distinct from both. 



Genus Crenis, Doubleday (1849). 



Crenis amulia, Cramer. (PL XVII. figs. 3 & 4.) 



Papilio amulia, Cramer, Pap. Exot. ii. pi. 180. figs. C, D (1779). 



Papilio amalia (sic), Fabricius, Ent. Syst. iii. pt. 2, p. 129, n. 398 

 (1793) ; Donovan, Nat. Rep. ii. pi. 40 (1824). 



Hub. Sierra Leone and Old Calabar {Coll. Druce). 



This beautiful species is little known, and is very rare. Mr. 

 Hewitson has, I believe, three specimens in his collection ; and Mr. 

 Druce lately picked up in an Old-Calabar collection a shattered ex- 

 ample, from which I have made my figure*. Cramer's figure is 

 scarcely recognizable. 



Genus Euryphene, Westwood (1850). 



EURYPHENE SWANZYANA, Sp. nOV. (PI. XVII. figS. 7, 8.) 



5 . AlcB supra fusccB, apice anticarum niveo ; fascia discali cceruleo- 



violacea, anticis abbreviata interno-anali. 

 Al<E subtus roseo-cinerece, squamis viridibus, prmcipue apud basin, 

 adspersce ; puncto anticis et macula posticis discoideis, nigris ; 

 maculis tribus anticis et quinque posticis niveis discalibus : anticis 

 quoque macula velut supra apicali : corpus supra nigro-fuscum, 

 subtus lateribus viridibus, thorace medio ochreo ; palpis ochreis ; 

 antennis nigris, ochreo clavatis. 

 Exp. alar. unc. 3~. 

 Hub. Gold Coast {Coll. Swanzy). 



This remarkable species seems almost to link the two genera Ro- 

 maleosoma and Euryphene ; it has the discoidal cells almost entirely 

 open, and in form, size, and the coloration of the upperside appears 

 to be nearly allied to R. eupalus of Fabricius ; on the underside it 

 more nearly approaches R. losinga of Hewitson. I believe, however, 

 * Mr. Druce has since obtained a second example in somewhat better condition.
