COB ALUS. — COBALOPSIS. 537 



hyaline spots on the primaries, these being almost obliterated in several specimens. 

 The females have larger spots, and are usually more brightly coloured. We have 

 dissected the genitalia of a male from Atoyac, Mexico, and of another from Manaure, 

 Colombia, and these no show no difference (see Tab. XCVIII. fig. 27). The primaries 

 have in this sex a pencil of long hairs below the origin of the first median branch, and 

 also some long hairs below the middle of the submedian nervure.

Hab. Costa Rica, Irazu (Rogers).— Guiana, Surinam 1 2 . 



Mr. Rogers obtained a single male in Costa Rica which we refer to this species, but 

 Salvin, who compared it with Moschler's type from Surinam, found that the white at 

 the base of the secondaries beneath was rather more extensive. 



COBALOPSIS, gen. nov. 

 The two Tropical-American species (Carystus dyscritus, Mab., and Pamphila edda, 

 Mab.) we place under this genus agree with Cobalus in the neuration of the wings, as 

 well as in their other general characters; but they have the male genitalia so remark- 

 ably formed that we think it best to separate them. We take P. edda as the type. 

 The harpes in the males of both species are greatly elongated, so that they project 

 considerably beyond the apex of the abdomen, and can be seen without dissection. 

 As in Cobalus, there is no trace of a brand on the primaries in this sex. Hesperia 

 pelora, Plotz, from Brazil, must also belong to Cobalopsis.
