This insect is not closely allied to any other known species ; in 

 general coloration it most nearly resembles the Honduras form of E. 

 myncea, but differs from it in many particulars. 



7. EUPTYCHIA TERRESTRIS, Sp. n. (PI. XXXIX. fig. 1.) 



AIce supra fuscce, fasciis duabus mediis obliquis, linea una submar- 

 ginali undata duabusque marginalibus directis nigro-fuscis ; pos-

Alee subtus pallidiores, fasciis mediis fuscis rufescentibus ; lineis 

 marginalibus velut supra fuscis ; anticce ocello apicali consueto 

 maculisque duabus argenteis; posticce maculis quinque ocellatis, 

 primo secundo quintoque nigris ochreo cinctis argenteoque bipu-

Underside uniform greyish brown ; central ocelli of hind wings

This species may readily be distinguished from E. myncea by the 

 distinct apical ocellus in the front wings above ; below by the bril- 

 liance and number of the silver spots, which are almost destitute of 

 iris, the pale hind marginal edge, and doubly dentated submarginal 

 lines.

This species, although closely allied to several acknowledged 

 Euptychia, has been placed in the genus Neonympl\a. It appears
