from it by the oblique (not transverse) discocellulars of both wings, the slightly- 

 depressed lower radial nervure of the primaries, &c. The males have a fringe of long 

 hairs along the upper edge of the abdominal fold of the secondaries. 



The antennae are rather more than half the length of the costa, and have an 

 elongate club, terminating in a long crook. The third joint is very short and almost 

 concealed. The primaries (Tab. C. fig. 22) are moderately elongate, arched on the 

 costa, and blunt at the tip ; the cell is less than two-thirds the length of the costa ; 

 the discocellulars are oblique, equal in length, the lower one being considerably longer 

 than the third median segment ; the lower radial is very slightly depressed at the base ; 

 the first branch arises from about the middle of the median nervure, the second from a 

 little distance before the lower angle of the cell. The secondaries are rounded at the 

 anal angle ; the discocellulars are oblique, long, and very faint. The body is slender. 

 The middle tibiae are not spined, the hind tibiae have two pairs of spurs.

Eight specimens of this species are before us. It perhaps most nearly resembles 

 Pqpias dictys, but the wings are darker above, and there is no trace of the minute 

 spots on either their upper or lower surface, and the hairs on the underside of the 

 palpi and body are darker ; the genitalia of the male, too, are quite differently formed 

 M. melas is also very like Mnasinous patage, but it is considerably smaller and differs 

 in other respects. For the genitalia of the male, see Tab. C. fig 23 



THARGELLA, gen. nov. 



The single obscurely coloured species referred to this genus differs from all the other 

 American Pamphilinse known to us in the very strongly arched costa. The primaries 

 are comparatively short and broad, with a short cell, the discocellulars oblique, aud the 

 lower radial depressed at the base. The neuration is very like that of the genera 

 Methion, MetMonopsis, and Epeus (the last two of these being branded in the male) 

 except that the first median branch arises from nearer the lower angle of the cell' 

 Amongst the Hesperiinee it closely approaches some of the species of Achlvodes 

 [A. calamus, &c), from which the oblique discocellulars and the depressed lower radial 

 nervure separate it. The antennas are almost as long as in the genus Falga 



The antenna are about two-thirds the length of the costa, and have an elongate 

 club, terminating in a long crook. The third joint of the palpi is short The
