110 HELICONID.E. 



nervure continued for some distance into the cell. Lower disco-cellular nervule very 

 slightly curved, directed very little outwards, joining the third submedian nervule where 

 it is bent at a slight angle. 

 Anterior Legs of the males slender, clothed with scales, and long, delicate, loosely scattered hairs. 

 Tibia about one third longer than the femur, nearly cylindric. Tarsus one-jointed, about 

 one fourth the length of the tibia, nearly cylindric, a little enlarged beyond the middle, 

 the apex tapering almost to a point. Anterior Legs of the females stouter. Tibia not quite 

 so long as the femur, smooth. Tarsus about one half the length of the tibia, five-jointed ; 

 the basal joint nearly cylindric, not quite twice as long as the rest combined, slightly spiny 

 beyond the middle, the apex with a stout spine on each side; second and third shorter, 

 nearly as broad as long, spiny below, with a stout spine on each side at the apex, and a bunch 

 of stiff hairs on each side at the base ; fourth joint narrower than the third, spiny, with a bunch 

 of stiff hairs on each side at the base ; fifth joint small, tapering, mucronate at the apex. 

 Middle and Posterior Legs rather elongate. The tibia? longer than the femora, very spiny, 

 the spurs distinct. Tarsi nearly as long as the tibia?, very spiny all round, the spines not 

 placed in rows below ; first joint quite as long as the rest combined ; second, third, and fourth 

 progressively shorter ; the fourth only two thirds the length of the fifth, which is equal in 

 length to the third, and broader than the preceding joints. Claws curved, grooved below. 

 Paronychia bilaciniate ; the outer lacinia not quite equal in length to the claw, strap-shaped, 

 fringed with hairs especially at the apex ; inner lacinia nearly triangular, shorter than the 

 claws. Pulvillus jointed, not equal in length to the claw. 

 Abdomen elongate, clavate, much longer than the inner margin of the posterior wings. 



Larva and Pupa unknown. 



This genus appears to be confined to Venezuela, where it occurs chiefly in the warmer regions, though sometimes 

 it is found on the higher country, to an elevation of six thousand feet, The only species known to me, is the one 

 figured; and the only specimens I have seen of it are those taken by Mr. D. Dyson, who informs me that it is an 

 insect of very slow flight. The males have a patch of long delicate hairs on the costa of the posterior wings above.
