EUREMA. 19? 



Anterior Legs of the male densely clothed with long hairs. Femur and tibia about equal in length : 

 the former compressed ; the latter subcylindric, narrowed near the base. Tarsus shorter than 

 the tibia, nearly cylindric, somewhat narrowed beyond the middle, conical or rounded at the 

 apex. Anterior Legs of the female less densely hairy, and rather longer than those of the male. 

 Tibia scarcely so long as the femur, subcylindric, unarmed. Tarsus rather shorter than the 

 tibia ; all the joints spiny below, and, except the fifth, with a stout spine on each side at the 

 apex, which is sometimes covered by a tuft of hair at the base of the next joint. First joint 

 three or four times the length of the second ; this nearly double the length of the third ; fourth 

 shorter than the second, very much broader on its lower, than on its upper, surface ; this nearly 

 covered by the fifth joint, which is scarcely visible from below. 



Middle and Posterior Legs rather large. Femora about the same length as the tibiae. Tibia? 

 spiny externally and internally ; the spines long, especially the inner ones, which are arranged in 

 two lateral series ; spurs long, stout. Tarsi with all the joints nearly cylindric, spiny above, 

 laterally, and, except the fifth, below ; the lateral spines longest ; those of the lower surface 

 not disposed in a regular series, those of the upper surface widely scattered. First joint 

 nearly ecpial to the rest combined ; second joint about one third the length of the first ; 

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

 of that joint. Claws short, curved, grooved below. Paronychia bilaciniate. Outer lacinia as 

 long as the claw, slender, obtuse at the apex. Inner lacinia short, narrow, subtriangular. 

 Pulvillus short, two-jointed ; the second joint broad. 

 Abdomen moderately robust, about two thirds the length of the inner margin of the posterior win^s. 



Larva and Pupa unknown. 



Eurema is very closely allied to the preceding genus, of which it is the Western representative. It may be known 

 from that genus by the different proportions of the joints of the palpi ; some slight difference in the neuration of the 

 wings ; and its more robust middle and posterior legs, of which the tibia; are spiny externally, and the tarsi spiny on the 

 upper surface ; the spines on the inside of the tibia? are also much longer. The form of the posterior win"-s varies 

 considerably, approaching in some species that of the preceding genus, in others presenting one or two distinct tails a 

 character most developed in the West Indian and African species. 



Eurema Delius offers some differences from most of the other species, especially in its more caudate posterior wind's ■ 

 but it much resembles, in all its characters, the female of Eurema Paullus. 



The general colouring of the upper surface is fulvous ; the apex of the anterior and outer margin of both pairs of 

 wings being black, the apex of the former marked with a white or transparent spot ; the disc itself is sometimes 

 marked with black. Eurema Kefersteinii is of a deeper hue than most of the species. Eurema Dione is remarkable 

 for its umber-coloured upper surface banded with black. The lower surface, in all the species, is beautifully varied 

 with different shades of brown or ochreous yellow. 



The Geographical Kange of the species, with one exception, is limited to the intertropical parts of the New World. 

 Two species appear confined to Brazil, and to be most common in the southern provinces ; two range over the northern 

 part of South America, extending along the eastern range of the Ancles to Bolivia ; one beautiful undescribed species 

 is found in Mexico ; Eurema Paullus is found in the Antilles and Jamaica ; and Eurema Delius in Western Africa 

 but its facies is so American, that Godart, who did not know its true habitat, suspected that it came from the New 

 World.
