Alia brunneis ; anticis plaga magna discali ochraeeo-brunnea ; posticis, lobulo anali medialiter rufo : subtus 

 fuscis, lineola ad cellularum fines fusca albido extrorsum limbata, linea communi discali fusca in posticis 

 extrorsum albo introrsum umbrino limbata ad ramum mediannm fracta ad marginem internum angulata, 

 linea altera communi submarginali in posticis lunulata fusca ad angulum analem nigricante ; posticis 

 lobulo anali nigro, macula nigra juxta eum albo atomata, macula nigra inter ramos medianos introrsum 

 umbrino cincta. 



$ mari similis, sed alis supra brunneis fere unicoloribus ; subtus omnino pallidioribus.

This species was founded upon a female specimen forming part of Van Patten's 

 Costa Rican collection, from which country Mr. Sogers has sent us several males, 

 which agree with others of that sex from Nicaragua and with the figure of Thecla 

 catena in Hewitson's ' Illustrations of Diurnal Lepidoptera.' T. denarius appears to be 

 a common species in those countries. 



157. Thecla sethon, sp. n. (Tab. LVII. figg. 14, 15 6 .) 



T. denario similis, sed anticis macula ochraeeo-brunnea nulla, area costali, prsecipue ad apicem, obscuriore ; 

 posticis margine externo ipso nigro : subtus brunnescentioribus ; posticis fascia discali rufescente (haud 

 umbrino) limbata. 



Hah Mexico, Milpas (Forrer), Jalapa (W. Schaus) ; Guatemala, Chisoy valley 

 (F. D. G. 6c 0. S.), San Geronimo, Duenas (F. B. G. & 0. S. 9 Champion), Calderas 

 (Champion); Costa Rica, Cache (Rogers). 



This is apparently an upland species, Mr. Forrer's specimen having been taken at 

 an altitude of nearly 6000 feet, and the Calderas examples (one of which, a male, we 

 figure) at a still higher elevation. The costal margin of the primaries is rather dark, 

 and there is no discal patch. These points seem to distinguish T. sethon from the 

 closely-allied T. denarius. 



158. Thecla plusios, sp. n. 



T. denario similis, sed alis undique brunnescentioribus, anticis area discali haud fusco adumbratis forsan 

 distinguenda. 



Hah Mexico, Jalapa ( W. Schaus) ; Guatemala, Zapote, Tucuru (Champion), Polochic 

 valley (F. D. G. & 0. S.), Coban ( Von Turckheim) ; Panama, Chiriqui (Ribbe). 



This is perhaps a doubtful species, but we have separated it, as we do not think our 

 specimens agree satisfactorily with either T. denarius or T. sethon. It appears to be a
