METISCTJS.— METHION. 563 



concealed. The primaries are elongate, blunt at the tip, and arched on the costa at 

 the base ; the cell is nearly two-thirds the length of the costa ; the discocellulars are 

 strongly oblique, the upper one about twice as long as the lower, the latter equal to 

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

 arises from the middle of the median nervure, the second shortly before the lower 

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

 cellulars are faint. The body is moderately stout. The middle tibiae are spined, and 

 the hind tibiae have two pairs of spurs. The primaries of the male (Tab. C. fig. 20) 

 have a conspicuous, oblique, curved brand, extending from the base of the second 

 median branch to the first at some distance from its origin, beneath which is a short 

 oblique piece.

Eab. Mexico, Teapa (H. H. Smith) ; Guatemala, Coban {Champion); Costa Rica, 

 Cache (Rogers) ; Panama, Chiriqui (mus. Staudinger). — Amazons ; Trinidad. 



Of this species we have several examples of both sexes from Teapa, and a male from 

 Trinidad, and Dr. Staudinger has lent us a male of it from S. Paulo, on the Amazons ; 

 all those from Guatemala, Costa Rica, and Panama are females, so that their determi- 

 nation is not quite certain. We had at first identified it as Hesperia immaculata, 

 Hew., but on examining the specimens so labelled in the Hewitson collection in the 

 British Museum we find that the males have a differently shaped brand. 



We also possess a female, from the Kaden collection, labelled Celmnorhinus 

 phceomelas* Hiibn., but this identification is very doubtful, our insect being much 

 larger. The females are so like those of Papias infuscatus that they are scarcely 

 distinguishable, except perhaps by their having a shorter and less conspicuous terminal 

 ioint to the palpi. Our descriptions and dissections have been made from a Teapa 

 specimen. For the genitalia of the male, see Tab. C. fig. 21. 



METHION, gen. nov. 

 The Central-American species placed by us in this genus agrees very nearly with 

 Methionopsis in the neuration of the primaries, and it is of a similar uniform nigro- 

 fuscous colour above ; but the terminal joint of the palpi is very short, the primaries 

 are without trace of a brand in the male, and the genitalia in this sex are very peculiar 

 in structure, the tegumen being formed by a single long slender piece. M. melas is 

 not unlike Achlyodes calavius, G. & S.*, of the group Hesperiinae, but may be known 



* This species (anted, p. 395) was doubtfully referred by us to Achlyodes ; we have since seeu a specimen 

 of it from Costa liica in Dr. Staudinger 's collection.
