108 HKLICONHXE. 



Anterior Legs of the male moderately stout, the tibia and tarsus clothed with scales and 

 thinly placed spreading hairs. Tibia about one third longer than the femur. Tarsus 

 about one third the length of the tibia, somewhat fusiform, tapering each way from the middle. 

 Anterior Legs of the female much longer than those of the male. Tibia slender, rather 

 longer than the femur. Tarsus about half as long as the tibia, five-jointed ; the basal joint 

 cylindric, longer than the rest combined ; second, third, and fourth short, transverse, nearly 

 equal; the fourth smallest; fifth much smaller, truncate; first, second, and third joints with 

 a spine on each side at the apex ; second, third, and fourth with a tuft of stiff hairs on each 

 side at the base, resting on the spine of the preceding segment. 

 Middle and Posterior Legs with the femora, tibiae, and tarsi of about equal length. Tibias 

 spiny, the spurs small. Tarsi very spiny all round, the spines at the sides longest, not 

 placed in rows beneath ; first joint not so long as the rest combined ; second about two fifths 

 the length of the first ; third about three fourths the length of the second ; fourth one half the 

 length of the second; fifth but little longer than the fourth. Claws curved. Paronychia 

 bilaciniate ; the outer lacinia not so long as the claw ; inner short, broad, subtriangular. 

 Pulvillus jointed, about as long as the claws. 

 Abdomen considerably longer than the inner margin of the posterior wings, slightly clavate. 



Larva and Pupa unknown. 



Olyras may readily be known from Lycorea by its longer antennas, and the very different neuration of its 

 posterior wings, and other less conspicuous characters. It is much more nearly allied to the following genus, and I 

 have hesitated for some time as to whether it would not be more advisable to consider Olyras and Athcsis as sections of 

 the same genus. The very distinct facies, and several marked though minor differences in structure, have led me to 

 separate them. The males have a space on the anterior margin of the posterior wings covered above with minute 

 scales, possessing a selenitic lustre, and furnished with a long patch of very long delicate hairs. 



Olyras Crathis was met with by Mr. Dyson in the mountains of Venezuela, up to about eight thousand feet 

 elevation, in the month of August : and in the lower country near La Guayra in December.
