In the collection of Mr. Hewitson. 



11. EUPTYCHIA USITATA, Sp. n. (PI. XXXIX. fig. 2.) 



Alee supra /usees linea media fuscescente continua post cellas posita, 

 tribusque marginalibus undatis ; anticce ocello apicali parvo nigro, 

 fiavo cincto et albo bipupillato ; posticce ocellis duobus similibus 

 analibus, inferno majore. 



Alee subtus pallidiores, lineis duabus mediis fuscis distinctis lituraque 

 ad cellce extimum, area apicali pallida ad apicem anticarum fus- 

 cescente, lineis marginalibus velut supra distinctioribus ; anticce 

 ocello apicali consueto punctisque minimis argenteis, macula 

 magna subanali indistincta ; posticce ocellis velut in E. myncea, 

 minoribus.

12. EUPTYCHIA SIMILIS, Sp. 11. 



Alee supra fuscce ; posticce lineis tribus marginalibus fuscescentibus, 

 media latiore, ocello uno subanali nigro ochreo cincto cceruleoque 

 pupillato : corpus fuscescens. 



Alee subtus pallidiores cinereo variee, lineis mediis velut in E. usi- 

 tata; area apicali cinerascente lineis tribus tenuissimis margina- 

 libus undatis, media ad angulum analem posticarum dilatata ; 

 fascia submarginali lata ochreo-fusca ; posticce macula subanali 

 nigra ochreo cincta, punctisque tribus submarginalibus fuscis: 

 corpus pallidum ; antennis supra fuscis nigro acuminatis, subtus 

 pallidioribus rubro nigroque acuminatis. 



Exp. alar. unc. 1-j-jt. 



Hab. Guatemala (central valleys) {Coll. Salvin). 



Allied to the preceding species, but very distinct. 



Var. Alee subtus pallidiores nee cinerascentes, lineis marginalibus 

 margini propioribus, anticce ocellis tribus fuscis pallidis valde in- 

 distinclis, posticce ocellis quinque majoribus {secundo et quinto 

 maximis) nigris.
