THEMESION. 615 



more or less pointed at the tip in the males, blunt in the females, with the costa 

 arched towards the base ; the cell is less than two-thirds the length of the costa ; the 

 discocellulars are strongly oblique, the lower one very short ; the lower radial is 

 greatly depressed at the base ; the first branch arises before the middle of the median 

 nervure, the second some distance before the lower angle of the cell. The secondaries 

 are broadly lobed at the anal angle, but they do not extend beyond the apex of the 

 abdomen ; the discocellulars are oblique and faint. The body is robust. The middle 

 tibise are without spines; the hind tibia? have two pairs of spurs, the upper pair short 

 or rudimentary. 



The males of the above-mentioned unnamed South-American species in our collection 

 have a pencil of long hairs above the abdominal fold of the secondaries. Proteides 

 mceros, Moschl., differs somewhat from the other species in the neuration of the 

 primaries, as well as in having longer upper spurs to the hind tibiae.

Hewitson's descriptions of Eudamus lebbceus and Hesperia lota appear to have 

 been taken from the same specimen, a female, as the type of the latter lent us by 

 Dr. Staudinger is ticketed E. lebbceus in what we believe to be Hewitson's own hand- 

 writing; this insect does not differ from the type of Hesperia certima, a male, in the 

 British Museum. No locality was mentioned by Hewitson for H. lota 3 . Dr. Staudinger 

 has also lent us two other females from Chiriqui. 



This species, as already noted, is very like Tisias myna in general coloration, but 

 differs from it in the absence of the submedian hyaline spot on the primaries and in 

 having some small black spots on the underside of the secondaries. In the type of 

 Hesperia certima, as in one of the females from Chiriqui, the primaries beneath have 

 three minute dark spots towards the apex.
