562 EHOPALOOEEA. 



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



terminating in a long crook. (The palpi are missing.) The primaries are moderately 



elongate, blunt at the tip, and arched on the costa towards the base ; the cell is a little 



less than two-thirds the length of the costa ; the discocellulars are strongly oblique, 



the upper one more than twice the length of the lower, the latter equal to the third 



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



arises from the middle of the median nervure, the second near the lower angle of the 



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



long and faint. The body is rather slender. The middle tibiae are without spines ; 



the hind tibiae have two pairs of spines. The primaries of the male (Tab. C. fig. 18) 



have an inconspicuous treble brand, which is hidden by the coarser scales : (1) a very 



slender streak extending along the whole length of the second median segment to its 



base, and there filling the angle between it and the first median branch ; (2) a short 



longitudinal streak just below this ; (3) a longer one above the submedian nervure 



towards the base. 



The genitalia of the male are not unlike those of some of the species of the genus 

 Rhinthon (R. megalops), in which genus the primaries have the brand formed of a 

 single streak along the upper edge of the submedian nervure.

Hab. Mexico, Orizaba (F. D. G. & H. J. Elwes) ; Panama, Chiriqui (mus. Staudinger). 



Mr. Elwes and myself captured a pair of this insect at Orizaba, and there is a male 

 of it from Chiriqui in Dr. Staudinger's collection. The form of the brand is exactly 

 similar in the two males, this character separating M. patage at once from the species 

 here referred to Euty chide umber (H.-S.). For the genitalia of the male, see Tab C 

 fig. 19. 



METISCUS, gen. nov. 



The Tropical-American species referred to this genus is one of the numerous forms 

 allied to Cobalus, but differs from it in having the primaries conspicuously branded in 

 the male, this brand again being peculiar in shape and position. The genitalia in this 

 sex are also very different from those of any of the allied insects known to us. In the 

 uniform fuscous coloration of the wings, M. atheas does not differ from many other 

 American Pamphilinae. The brand is not unlike that of the species of Lerema, except 

 that the lower piece is absent. 



The antennae are about half the length of the costa, and have an elongate club, 

 terminating in a long crook. The third joint of the palpi is very short and almost
