218 NYMPHALID.F. 



simple, curved forward. Discoidal nervure arising from the base of the second median 

 nervule, sometimes bent at a considerable angle soon after its origin. Cell sometimes open, 

 sometimes closed by a rudimentary nervide, terminating at the origin of the third submedian 

 nervule. 



Anterior Legs of the male with the femur, tibia, and tarsus nearly equal in length, the first 

 being slightly the longest ; all clothed with scales and very delicate long hairs. Tibia slender, 

 broadest at the base, nearly cylindric, slightly curved. Tarsus slender, nearly cylindric, 

 tapering to a point at the apex. Anterior Legs of the female scaly. Femur rather longer 

 than the tibia. Tibia cylindric, rather longer than the tarsus, armed internally with one or 

 two scattered spines. Tarsus nearly cylindric. First joint more than equal in length to the 

 rest combined, armed with some scattered spines below, and two stout spines on each side 

 at the apex ; second joint little more than one fourth the length of the first, armed below 

 with several spines, and with two on each side at the apex ; third joint rather shorter and 

 slenderer, armed below with two or three scattered spines, and with a long spine on each 

 side at the apex ; fourth joint shorter than the third, armed with a stout spine on each side 

 at the apex ; fifth joint smaller, but rather longer than the fourth, mucronate at the apex. 



Middle and Posterior Legs moderately robust ; the femora of the former longer than those of the 

 latter, equal in length to the tibia. Tibiae thinly spiny externally, densely so laterally. 

 Spurs stout. Tarsi with all the joints thickly spiny below and laterally ; the first joint, and 

 sometimes one or more of the other joints, with a few spines above. First joint one fourth 

 longer than the rest combined ; second not quite one fourth the length of the first ; third 

 shorter than the second ; fourth one eighth the length of the first ; fifth slightly longer than 

 the second. Claws curved, grooved below, moderately large. Paronychia with the outer 

 lacinia hairy, slender, about equal in length to the claw; the inner lacinia rather shorter, 

 broader, very hairy. Pulvillus about as long as the claw ; the second joint broad. 

 Abdomen rather slender, about three fourths the length of the inner margin of the posterior wings. 



Larva and Pupa unknown. 



From the preceding this genus differs in so many characters that I have hesitated to place them together ; yet 

 I can find no other position for it and its allies, without equally breaking the regular succession of the genera. In 

 truth, the more we known of any group, the more difficult it becomes to range the specie? in a direct series. This 

 may, to a certain extent, be done, if we are confining ourselves to the species from one country, or to those of countries 

 in the same parallels of latitude ; but, if we extend our observations to the whole species of a large group, we find 

 them so interwoven in their affinities and analogies, that it becomes impossible to unravel them and draw them into a 

 line. 



Cybdelis and the following genera have many of the characters of Vanessa and its allies ; at the same time they 

 exhibit a marked resemblance to the Hipparchiaj, in the swollen nervures of their anterior wings. 



Cybdelis Mnasylus presents a character occurring in the previous genus, the contact of the costal nervure and the 

 first subcostal nervule; but there is not the same absolute blending of the nervure and nervule which occurs in 

 Anartia Jatrophas. 



I had considered that the second section of this genus ought to be looked on as generically distinct; but a more
