MEGISTIAS. 575 



Hah. Mexico, Presidio de Mazatlan (Forrer), Mazatlan {G. Mathew), Acapulco, 

 Dos Arroyos, and Rio Papagaio, all in Guerrero {H. H. Smith), Paso de San Juan 

 {coll. Schaus), Atoyac {Schumann & H. II. Smith), Valladolid in Yucatan (Gaumer); 

 Hondueas, Ruatan I. {Gaumer). — Venezuela, Puerto Cabello, La Guayra 2 ; Guiana. 



This is a fairly common species in Mexico, from which country we have received 

 numerous examples, from both the Atlantic and Pacific slopes. 



Our series shows considerable variation ; the small spots at the middle of the costa 

 of the primaries (as well as those beyond the cell) are sometimes very indistinct above, 

 but they are always conspicuous beneath, where they are confluent. The underside 

 of the secondaries in some individuals is darker than in others, and the ferruginous 

 markings are paler, approaching to fulvous. Our figures are taken from Mexican 

 specimens. For the genitalia of the male, which are not unlike those of Cobalopsis 

 dyscritus (Mab.), see Tab. CI. fig. 15, the insect in this respect differing from all others 

 of the genus. 



c. Primaries usually with an oblique series of ochreous spots. 



8. Megistias epiherus. (Tab. ci. figg. 16, 17, 18, s .) 



Pamphila epiberus, Mab. Le Nat. 1889, p. 134, f. 2 '. 



Alis fuscis, aiiticis costa et maculis, venis divisis, serie obliqua inter ramos medianos, ochraceis, posticis squamis 

 et pilis coloris ejusdem vestitis : subtus ochraceo-ferrugineis, anticis dimidio interiore a basi usque ad 

 ramum medianum nigrescentibus et maculis duabus discalibus flavis.

 Hob. Mexico, Misantla, Vera Cruz {F. D. G.), Coatepec {coll. Schaus), Atoyac, Teapa 



(H. H. Smith); Guatemala, San Geronimo {Champion); Honduras {Dyson); Panama, 



Chiriqui 1 {ex Staudinger).— South America to Brazil; Trinidad. 



Of this very variable species we have examples of each sex, from Atoyac and 

 Teapa, which are dark fuscous on the upperside, with no spots, and, again, we have 

 others from the same localities with a well-marked oblique tapering series of ochreous 

 spots on the primaries ; they vary also in a similar manner in the colour of the under- 

 side of the wings. Between these two extremes we have intermediate forms. We 

 have dissected four males, and the genitalia show no difference of any importance, 

 see Tab. CI. fig. 18. Our figure of the insect is taken from a specimen from 

 Chiriqui. 



9. Megistias leucone, sp. n. (Tab. CI. figg. 19, 20, 21, <$ .) 



Alis fuscis, maculis duabus distinctis in linea obliqua inter ramos medianos, ochraceis, costa dense, alitor sparsim 

 squamis flavis tectis, posticis inter ramos ultra cellulam quoque squamis coloris ejusdem dense vestitis : 

 subtus ut supra, anticis dimidio interno a basi usque ad ramum medianum secundum obscure fuscis.
