 Rica, Cache (Bogers); Panama, Chiriqui (mus. Staudinger), Taboga I. (G. Mathew). — 

 Colombia 2 3 4 ; Venezuela 1 . 



Dr. Staudinger has lent us the types of Carystus erebina and C. kasus, Moschler, 

 from Colombia, and these do not differ from that of Hesperia cynea, Hew., from 

 Venezuela. We possess several specimens of the same species from Central America, 

 all of which are males. C. kasus represents a small form, and we have others like it 

 from Taboga Island and Colombia. C. tersa, Moschler, based upon a single female 

 example from Colombia, probably belongs here. A male of B. cynea from Atoyac is 

 figured. For the genitalia, see Tab. XCVIII. fig. 3. 



3. Rhinthon alus, sp. n. (Tab. XCVIII. figg. 4, 5, 6, 6 .) 



E. cynea similis, sed anticis maculis discalibus angustioribus : capite et tborace fuscis (nee viridibus) : subtus 



anticis ad angulum analem pallide fuscis ; palpis obscurioribus.

Hab. Panama (Bibbe, in mus. Staudinger). — Guiana ; Amazons ; Bolivia. 



Dr. Staudinger has lent us two male specimens of this species from Panama under 

 the MS. name of Carystus alus, Mabille, and we have several others from South 

 America agreeing with it. B. alus is exceedingly like B. cynea, Hew., and the male 

 has a similar brand on the primaries, but the head and thorax are clothed with fuscous 

 (instead of green) hairs above, and the hyaline spots are narrower. The genitalia of 

 the two species are very similar : for those of B. alus, see Tab. XCVIII. fig. 6. 



c. Primaries immaculate above.

 in plica abdominale posticarum, pilis longis penicillatis : subtus obscurioribus et purpureo tinctis, anticis 

 ad angulum analem multo pallidioribus, apice et margine externo grisescentibus ; posticis margine externo 

 et interno coloris ejusdem; palpis et corpore subtus griseis.
