PAPIAS.— MNASINOUS. 561 



3. Papias microsema, sp. n. (Tab. c. figg. 14, 15, s .) 



Alis fuscis, unicoloribus : subtus pallidioribus et rufescentioribus, anticis angulum analem versus dilutioribus, 

 punctis duobus, uno inter ramos medianos primum et secundum, altero ultra id, uno quoque subapicali, 

 posticis quatuor in serie curvata ultra cellulam (omnibus frequenter absentibus), albidis ; palpis subtus 

 pilis ochraceis et fuscis intermixtis vestitis. 



$ mari similis. 



Hab. Mexico, Teapa (H. H. Smith) ; Costa Rica, Irazu (Rogers) ; Panama, Chiriqui 

 (mus. Staudinger). — Brazil, Chapada. 



Dr. Staudinger has lent us three specimens of this insect for examination, two under 

 the name of Pamyhila microsema, Mabille, and one under that of P. phceomelas, 

 Hiibner, and we possess others from Mexico, Costa Rica, and Brazil, apparently 

 agreeing with them. 



We cannot find that Mabille's name has been published, and the identification of 

 Hiibner's species is very doubtful. 



P. microsema is exceedingly like P. phainis, but has differently formed genitalia in 

 the males. The spots on the underside of the wings are quite distinct in two of the 

 three specimens seen from Chiriqui, which we are unable, unfortunately, to dissect ; 

 they are absent or barely indicated in the others. We have dissected several examples 

 from Teapa and Chapada, and we find they agree perfectly, see Tab. C. fig. 15. A 

 Chiriqui specimen of the insect is also figured. 



4. Papias phainis, sp. n. (Tab. C. fig. 16, s .) 



Alis nigro-fuscis, unicoloribus : subtus ut supra, sed rubescentioribus, anticis angulum analem versus pallidi- 

 oribus ; palpis pilis fuscis et aureis intermixtis vestitis ; ciliis fuscis. 

 2 mari similis. 



Hab. Mexico, Atoyac (H. H. Smith), Misantla (F. I). G.) ; Guatemala, San 

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



We have about a dozen examples of this species, which can only be separated from 

 the immaculate form of P. microsema by the structure of the genitalia of the male (see 

 Tab. C. fig. 16). P. phainis is also extremely like Pamphila simjjlicissima, H.-S., 

 which is here referred to a different genus, but may be distinguished from that insect 

 by the stouter terminal joint to the palpi and by its larger size. 



MNASINOUS, gen. nov. 

 The single species from Central America that we refer to this genus is of a uniform 

 nigro-fuscous colour, like those of Papias, Methion, Methionojpsis, and other Tropical- 

 American genera of Pamphilinie. It appears to be an isolated form, differing in its 

 male-characters from all its allies. The brand is not unlike that of certain species of 

 Eutychide (E. asema), but the lower arm of the >-piece is absent, and the upper arm 

 is much more elongate.
