366 EHOPALOCEE^. 



We have specimens of several unnamed species in our collection, apparently congeneric 

 with Eracon biternata. Arteurotia bitfonia, Moschler, of which we have recently 

 examined the type, also belongs to the same genus. 



1. Eracon biternata. (Tab. LXXXIII. %g. 1, 2 s .) 



Arteurotia biternata, Mab. Le Nat. xi. p. 217, f. 4 (1889) \ 



Alis brunneis, fasciis tribus communibus margini externo plus minusve parallelis obscurioribus ; anticis punctis 

 tribus subapicalibus triangulum formantibus et tribus ad medium costse linea recta positis (duobus in 

 cellula in macula nigra sitis), omnibus semihyalinis : subtus magis ferrugineis, fasciis indistinctis, punctis- 

 hyalinis ut in pagina superiore : palpis segmento apicali fusco, reliquis subtus et corpore infra albidis. 



Hab. Panama, Chiriqui (Bibbe, in mus. Staudinger 1 ). 



Dr. Staudinger has lent us the type of this species, which was taken in Chiriqui by 

 Eibbe and described by M. Mabille in 1889 1 . It is the only specimen we have seen, and 

 from it our figure is taken. 



GORGOPAS, gen. nov. 



This genus is proposed for a small group of species having the antennae and the 

 general shape of the wings like the members of Bellicia, but in which the males have 

 a distinct costal fold and no tuft of hairs near the base of the costal margin of the 

 secondaries. There is no tibial tuft on the hind legs, nor are the tibial spines fringed. 

 The upper portion of the head and prothorax is usually bright metallic green, and in 

 some cases, as in G. chlorocephala (Latr.), the same colour spreads over the bases of the 

 wings. Telemiades hybridus, Mabille, also belongs to this genus. The harpes of the 

 male genitalia are symmetrical. 



l. Gorgopas viridiceps. (Tab. LXXXIII. figg. 3, 4, 5 s .) 



Achlyodes viridiceps, Butler & Druce, Cist. Ent. i. p. 115 (1872) l ; P. Z. S. 1874, p. 370 \ 



Alis nigricanti-brunneis fere unicoloribus ; anticis ad apicem vix pallidioribus, punctis tribus in linea recta 

 positis subapicalibus semihyalinis : subtus pallidioribus, posticis ad angulum analem pallide brunneis,. 

 fasciis tribus indistinctis margine externo subparallelis notatis : palpis supra, capite inter oculos, pro- 

 thorace supra, et tegulis nitide aureo-viridibus, palpis infra griseis. 

 2 mari similis, sed alis pallidioribus dimidio distali pallide brunneo, fasciis indistinctis obscurioribus notatis :. 

 subtus posticis ad angulum analem pallidis, fasciis indistinctis notatis. 



Hab. Nicaragua, Chontales (Belt) ; Costarica (Van Batten 12 ). —Colombia; Vene- 

 zuela; Amazons; E. Peeu. 



This species, of which we have the type from Costa Rica before us, is closely allied 

 to Hesperia chlorocephala, Latr., which we now refer to this genus, but differs constantly 

 in the darker colour of the wings and the absence of the shining green colour which 

 overspreads the base of the wings of the latter species. The ranges of the two are to- 

 some extent coincident, but G. chlorocephala has not been detected within our limits.
