EUDAMUS. 281 



Though Hewitson described l this well-marked species from specimens obtained by us 

 in Guatemala, it had long been represented in the Berlin Museum by examples procured 

 by Deppe in Southern Mexico. In the latter country we now know it to be common 

 in the lowlands bordering both oceans, and ascending the mountains to a height of 

 4000 feet. 



In Guatemala it occurs under similar circumstances. The most southern point of its 

 range appears to be Costa Rica, where Van Patten found it. 



The well-defined straight snow-white band on the underside of the secondaries renders 

 this species easy of recognition. 



In Mr. Schaus's collection there is a specimen taken at Coatepec in which the 

 primaries are wholly without the usual diaphanous spots. 



The male genitalia of this species differ both from those of E. zilpa and E. catillus. 

 The harpagones terminate in an upturned truncate lobe, ending in diverging spines — 

 one directed outwards, the other inwards. (See Tab. LXXV. fig. 11.) 



8. E. algous section. No dark subtriangular spot near the apex of the primaries.

Described by Hewitson from a Nicaraguan specimen, and now known to be generally 

 distributed over a large portion of Central America from Southern Mexico to Panama. 

 There is a specimen in the Hewitson collection said to have come from Ecuador. 



This species has no near allies that we are acquainted with, the position of the white 

 discal patch near the base of the tails on the underside of the secondaries and the 

 arrangement of the hyaline spots of the primaries render it easy of recognition. 



E. alcceus is a species of the lowlands, and is probably limited in its range to an 

 altitude of 2000 feet and under. 



The male genitalia have the harpagones very truncate, an upturned spine proceeds 

 from the further edge of the dorsal fissure, beyond which the harpagones terminate in 

 a slightly concave, almost perpendicular, edge. (See Tab. LXXV. fig. 12.)
