152 LEPIDOPTERA. 



bluish-wliite stripes, and one or two scarlet spots near the anal 

 angle of the hind wings. 



The species of Zeonia, Swains., are transparent-winged insects, 

 with black borders and stripes ; the hind wings are more or less 

 marked with crimson. 



Barbicornis, Latr., is a singular black and yellow tailed insect, 

 with pectinated antennae like a moth. Some authors include it 

 with the Lithosiidce. 



The species of Helicojns, Fabr., are very delicately-formed 

 insects, which are among the commonest of the South American 

 Lemoniidce. They are of a creamy white, yellow towards the 

 base, with black borders, and the under side of the hind wings is 

 adorned with silvery spots, Mr. Bates found two species of this 

 genus common in damp shady places near Pard, and observes : 

 " Their flight is very slow and feeble ; they seek the protected 

 under surface of the leaves, and in repose close their wings over 

 the back, so as to expose the brilliantly-spotted under surface." ^ 



The species of Emesis, Fabr., are rather dingy insects. They 

 are brown insects, with more or less pointed fore wings, near the 

 tip of which is often a white spot, and they are traversed by 

 darker lines. The under surface is generally reddish yellow, 

 with the lines more distinct. 



Lemonias, Hiibn., incJudes a number of small species, which are 

 generally of a black colour, more or less of the wings, especially 

 towards the base, being red or blue, spotted with black, at least 

 on the under surface. 



The genus Nymphidium, Hiibn., is not unlike Di/namine, among 

 the Nymphalidx, in appearance. Many of the species are white or 

 yellowish white, Avith brown or yellowish-brown borders. 



Tlieope, Westw., includes small species, with broad truncated 

 fore wings ; they are blue, more or less bordered with brown, and 

 the under surface is brown or yellowish, and is in most cases 

 absolutely uniform in colour, being often destitute of any markings 

 whatever. 



The genus Aricoris, Westw., includes several rather long- 

 winged black and yellow butterflies ; and Stalachtis, Hiibn., con- 

 tains several species not unlike Heliconince in shape and colour. 

 They are about two inches in expanse, and are black, with reddish 

 or yellowish markings ; other species are partly transparent, thus 

 resembling Ithomice.
