angle ; the cell is less than half the length of the wing ; the discocellulars are faint 

 and transverse. The body is moderately stout. The middle tibiae are conspicuously 

 spined, and the hind tibia? have two pairs of spurs. The primaries (Tab. CII. fig. 22) 

 are without a brand.

Hab. Panama, Chiriqui (Eibbe). — Guiana ; Amazons ; Brazil. 



We have nine examples of this species, one only of which is from our country. 

 P. hypargyra is very like P. menetriesi (Latr.) and P. koza (Butl.) on the upperside, 

 but the secondaries are very differently coloured beneath. 



Dr. Staudinger has sent us specimens of this insect from the Amazons under the 

 name of Pamphila hypargyra, H.-S., and we have a single male from Chiriqui agreeing 

 with them, as well as others from Brazil. 



Our single female from Ega is much paler and shows a distinct series of greyish 

 streaks on the secondaries above towards the apex. For the genitalia of the male, see 

 Tab. CII. fig. 23. 



ZEN IS, gen. no v. 

 We take Hesperia minos, Latr., as the type of this genus, which will probably also 

 include Carystus ozota, Butl. ; the former is a widely distributed insect in Tropical 

 America, the latter inhabits Venezuela and Brazil. It differs from Carystus in having the 

 primaries narrower, with the outer margin concave, the first branch arising from nearer 

 the base of the median nervure, and the second median segment very elongate ; the 

 males are without a brand (as in Carystus), but have a pencil of long hairs beneath the 

 first median branch. 



The antennae are less than half the length of the costa, and have a moderately stout 

 club, terminating in a long crook. The palpi have their third joint short and erect. 

 The primaries are narrow and elongate, concave on the outer margin, blunt at the 

 apex ; the costa is slightly arched at the base, then straight to the apex ; the cell is a 

 little less than two-thirds the length of the costa ; the discocellulars are' very oblique, 

 the upper one three times as long as the lower, the latter of the same length as the 

 third median segment; the lower radial is depressed at the base; the first branch 

 arises considerably before the middle of the median nervure, the second close to the 

 lower angle of the cell. The secondaries are slightly lobed at the anal angle ; the cell 

 is not quite half the length of the wing ; the discocellulars are faint. The body is
