The species are so much alike that they can only be separated for certain by the 

 structure of the genitalia of the males ; four specimens of each have been dissected.

We are indebted to Dr. Staudinger for the loan of a male specimen identified by 

 Moschler as Hesperia infuscata, Plotz. It is the commonest of several extremely 

 closely allied Central- American species, the males of which are without a brand on the 

 primaries. In this sex the fore wings are more pointed than in many of its congeners. 

 Dr. Staudinger has also sent us specimens of the same species under the names of 

 Cobalus umber of Herrich-Schaffer and Pamphila Integra of Mabille. 



We have dissected four males, including one from Para, and they show no difference 

 in the form of their genitalia, for which see Tab. C. fig. 11. 



2. Papias dictys, sp. n. (Tab. C. figg. 12, 13, 6 .) 



Alis brunneo-fuscis, puncto minutissimo indistincto subapicali albido (interdum obsolete*) : subtus rufescenti- 

 oribus, anticis angulum analem versus pallidioribus, area mediana obscuriore, posticis punctis tribus fere 

 obsoletis in area discali quoque albidis ; palpis subtus pilis flavis et fuscis intermixtis vestitis. 

 5 mari similis, sed punctis subtus magis distinctis.

 Chisoy Valley (F. I). G. & 0. S.), Panima and San Geronimo in Vera Paz, Zapote 

 (Champion); Costa Rica, Cache (Rogers); Panama, Chiriqui (mus. Staudinger). 



Very like P. infuscatus, but smaller and much redder beneath, and usually with a 

 minute whitish subapical spot on the primaries, the primaries less pointed at the tip 

 in the male. The genitalia in this sex are also differently formed, as will be seen by a 

 reference to our Plate. 



We have dissected four males from different localities, and these show no differences 

 whatever in their structure, see Tab. C. fig. 13. 



Our series contains twelve specimens, half of which are from San Geronimo. 

 Dr. Staudinger has also sent us two examples from Chiriqui for examination.
