Bab. Panama, Chiriqui (mus. Staudinger). — Guiana 1 ; Amazons. 



There is a specimen of this well-marked Tropical-American species in Dr. Staudin- 

 ger's collection from Panama, and we therefore include it here. For the genitalia of 

 the male, see Tab. XCVI. fig. 36. 



THESPIEUS, gen. nov. 



This genus includes numerous Tropical-American forms : Hesperia dalmani, Latr., 

 which we take as the type, H. lutetia, H. himella, II. ovinia, and ff. opigena, Hew., 

 Proteides othna and P. xarippe, Butl., P. cicus, Mab., and others. It approaches 

 Mconiades, but has the secondaries much less lobed at the anal angle, scarcely 

 extending beyond the apex of the abdomen, the brand on the primaries of the male 

 very differently placed, the genitalia in this sex dissimilarly formed. From Phemiades 

 it may be separated by the stouter club to the antennas and the more oblique brand on 

 the primaries in the male. Three species only enter within our limits. All of them 

 have hyaline spots on both wings, and the underside of the secondaries peculiarly 

 coloured. //. ovinia and II opigena, however, differ somewhat in this respect. 



The antennas are about half the length of the costa, with a stout club, terminating 

 in a moderately long crook. The palpi are densely scaled, the third joint very short 

 and almost concealed. The primaries are somewhat pointed at the tip, and usually 

 with the outer margin more or less concave ; the cell is nearly two-thirds the length 

 of the costa, and considerably produced at the apex ; the discocellulars are strongly 

 oblique, the lower one extremely short, not half the length of the third median 

 segment ; the lower radial is greatly depressed at the base ; the first branch arises 

 a little before the middle of the median nervure, and the second near the lower angle 

 of the cell. The secondaries are feebly lobed at the anal angle, reaching about as far 

 as the apex of the abdomen ; the discocellulars are faint. The body is robust, very 

 hairy beneath. The middle tibia? are spined and the hind tibiae have two pairs of 

 spurs, the hind tibiae clothed with long hairs on their outer edge. The primaries 

 of the male have a narrow, conspicuous, oblique, interrupted brand, extending from 

 the base of the second median branch to about the middle of the submedian nervure.
