second branches (0. Emilia) ; the discoiclal cell being open in the former species, but imperfectly closed in the 

 latter at about one third of the length of the wing. 



Hind Wings broadly subtriangular-ovate. Outer margin entire, scarcely scalloped. Costal vein extending to 

 the outer angle of the wing. Precostal vein short, erect, slightly curved. Postcostal vein branching at a 

 moderate distance from the base. The upper disco-cellular vein short, branching off very close to the origin 

 of the branch of the postcostal, forming the slightly curved branch of the discoidal vein: the _ lower_ disco- 

 cellular either obsolete (0. Azeca), or very slender, and uniting mth the median vein at a little distance 

 before the origin of the third branch (0. Emilia). 



Fore Legs of the male very minute and slender. Tibia and tarsus clothed with long hairs. 



In their peculiar colouring, especially on the under surface of the wings and the flisciated bodies, the few butterflies composing 

 this genus bear a certain resemblance to" some of the species of Limenitis ; whilst their elongated fore wings give them an apparent 

 relatVon to the Heliconiidaj. I regret that the only specimens I have seen of this genus are in so imperfect a state, that I can give 

 but the preceding short generic character. The two species, O. Azeca and O. Emilia, although agreeing in general appearance and 

 colouring, differ from each other in the condition of the discoidal cell in both pairs of wings ; it being entirely open in the former, 

 whereasit is closed in the latter. The lower disco-cellular vein, in all the wings of the latter species, is, however, much more slender 

 than in the preceding or following genera, where it occurs.

Body and wings moderate-sized ; the latter scalloped ; fore wings angulated below the apex. 

 Head moderate-sized, with a tuft of hairs at the base of each antenna. 



Eyes pi-orainent, hairy in E. Hiarbas (naked in E. Ophione). 



Labial Palpi elongated, rather slender, finely hairy, porrected further than the length of the head, and elevated 

 to about the middle of the eyes; terminal joint "about half the length of the preceding, slender. 



Antenna; not quite half the length of the fore wing, slender; terminated by a slight, gradually formed, but very 

 short club, obtuse at the tip. 

 Thorax of moderate size, woolly in front and behind. 



Fore Wings moderate-sized". The costal margin but slightly arched ; apical angle subtruncate. Apical margin 

 scalloped, angulated below the apex at the" extremity of the upper discoidal vein. The veins arranged as in 

 Cystineura. Upper disco-cellular very short, rather oblique : middle disco-cellular scarcely longer, slightly 

 curved : lower disco -cellular nuich longer, straight, transverse, but very slender, uniting with the median vein 

 exactly at the origin of the third branch. 



Hind Wings moderate-sized, subtriangular-ovate. Outer margin strongly scalloped. Veins arranged as in Olina. 

 The upper disco-cellular vein arising very close to the base of the branch of the postcostal vein : the outer 

 disco-cellular transverse, very slender in E. Hiarbas, and uniting with the median vein at a little distance 

 before the origin of the third branch. In E. Ophione the outer disco-cellular is obsolete, so that the discoidal 

 cell is open in this species. 



Fore Legs of the male very slender and short. The femur very delicately hahj. The tibia and tarsus of equal 

 thickness, and of nearly" equal length, being together about one fourth longer than tlie fenuir. Fore Legs of 

 the female considerably longer than those of the male, but equally slender. Tarsal portion dilated into an 

 elongate-oval mass, with the three intermediate joints armed at the tip within with a pair of long sharp spines ; 

 terminal ioint very small and oblique. 



Four Hind ^ Legs rather short, thickly scaly. Tibia armed beneath with rows of short spines. Tarsus _ more 

 thickly clothed beneath and at the sides with rows of short spines. Claws small, curved, acute, simple. 

 Paronychia very slender, bifid ; the outer division almost setaceous.
