DAMAS.-— OESES. 621 



DAMAS, gen. nov. 



A single Tropical-American species, Goniloba clavus, H.-S. (=Proteides ampyx, 

 Mab.), is referred to this genus. Damas is allied to Thracides, the type of which is 

 T. phidon (Cram.), but differs from it in having a conspicuous and very dissimilarly 

 shaped brand on the primaries of the male. 



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

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

 and concealed. The primaries are elongate, somewhat pointed at the tip, arched on 

 the costa and straight on the outer margin ; the cell is less than two-thirds the length 

 of the costa ; the discocellulars are very oblique, the upper one longer than the lower, 

 the latter longer than the third median segment ; the lower radial is slightly depressed 

 at the base ; the first branch arises before the middle of the median nervure, the second 

 a little before the lower angle of the cell. The secondaries are produced at the anal 

 angle; the discocellulars are very oblique, the upper one very faint. The body is 

 robust. The femora are very hairy. The middle tibiae are furnished with spines, the 

 hind tibiae with two pairs of spurs. The primaries of the male have a conspicuous 

 brand formed of two pieces, the upper one somewhat triangular and extending alono- 

 the second median segment to the base of the second median branch, the other in the 

 form of a short longitudinal streak immediately below it.

Eab. Panama, Chiriqui 2 (Tr'oUch, in mm, Staudinger). — Amazons, Para. 



Dr. Staudinger has lent us a male specimen (the type) of P. ampyx, Mabille, from 

 Chiriqui, which agrees with three others from South America in our collection ; one of 

 these we believe to be the type of Herrich-Schaffer's Goniloba clavus. We also have 

 another male from the Amazons, evidently belonging here, but the spot in the cell of 

 the primaries is not visible on the upperside. 



Our figures are taken from South -American examples. For the genitalia of the 

 male, see Tab. CV. fig. 4. 



ORSES, gen. nov. 



This genus, of which we take Eesperia cynisca, Swains,, as the type, is a very 

 remarkable one, inasmuch as the sexes have the primaries not only dissimilarly marked
