Genus Erycina. 99 



From Bogota, in the Collection of the British Museum. 



'J'his species most nearly resembles Z. Amazon, but is imme- 

 diately distinguished from it by tlie shape and smaller size of the 

 crimson spot on the hinder wings. From Z. Batesii it is distin- 

 guished by its larger size and the shape of the hinder wings, which 

 have a transverse black band. 



Zeonia Batesii, W. W. Saund. (PI. X. figs. 1 and 2.) 



Anterior wings much pointed, transparent, with the base, ante- 

 rior margin, outer margin, nervures and a nearly central transverse 

 band, black. Posterior wings narrow, about twice the length of 

 the body, terminated by a long narrow tail-like appendage in con- 

 tinuation of the outer margin, and nearly as long as the wing; 

 and also by a sharp-pointed tooth-like projection in continuation 

 of the inner margin, transparent, with a black band along the 

 inner and outer margins, uniting before the apex, and forming 

 there a large black patch, which is crossed in the centre by a 

 crimson slightly curved band nearly as long as the wing is broad, 

 and having below an obsolete band of minute white spots. The 

 nervures, tail and tooth-like projection of the hinder wings* are 

 black. The underside of the wings are marked as the upper. The 

 head, antennae, body and legs are black. 



Expansion of wings 1 ^^ inch. 



Collected in the Upper Amazon region by Mr. Bates.

The female is very similar to the male in size, colour and mark- 

 ings, chiefly differing in the anterior wings being more rounded 

 on the exterior margin, making them appear less pointed, and in 

 the tails being greatly diverging and somewhat curved inwards. 

 In Mr. Hewitson's Collection. 



This is a small species, with well-marked characters, having in 

 the hinder wings no longitudinal band, as in all the other species 

 of this section. 



Zeonia Hdiconoides, Swain. $ . (PI. X. fig. 5.) 



Under an impression that the figure given in the " Zoological 

 Illustrations" of Mr. Swainson, pi. 3, 2nd Series, was that of the 

 male of this species, the female was figured in the accompanying 

 PI. X. fig. 5. Examining the details given by Mr. Swainson 

 there can be no doubt that his figure represents a female. A 

 second figure of the female of so rare an insect will not be, how-
