200 Mr. H. W. Bates on the Nymphalinze 
colour at the base, and with a long pencil of dark-brown hairs at the com- 
mencement of the abdominal margin. Beneath, same as in Cramer’s figure 
of the Q. 
Very abundant at St. Paulo, Upper Amazons; the males being 
attracted by scores to the dung of vultures, on the borders of the 
woods. 
37. Eunica Sophonisba, Cramer, 295 a. B., 2. 
¢d. Same shape as the 9. Above rich deep black, with a spot near 
the hind angle of the fore wing and a broad outer border to the hind wing 
of a fine sapphire-blue colour. Beneath same as the 2, except that the 
ground-colour is of a brighter metallic-green colour, and the central streak 
of the hind wing red, instead of yellow; the white belt of the 9 being, of 
course, absent. 
This most beautiful of all the species of Hunica resembles the Call- 
thee in the colours and markings of its under surface ; it is, however, 
a true Hunica, as shown by the swollen bases of the fore-wing ner- 
vures and the slenderness of the antennal club. It is an exceedingly 
wary insect, and one of the most difficult to capture ; so that, although 
I saw many, I did not obtain more than three or four specimens. It 
occurred at St. Paulo, Upper Amazons, and also near the mouth of 
the Rio Negro. 
Genus Lisyruina, Felder, Ein neues Lepid. p. 49. 
This genus, although agreeing with Hunica in style of coloration, 
in neuration, and in the swollen bases of the costal and median fore- 
wing nervures, must be kept distinct on account of the great elonga- 
tion of the palpi. The species constituting it differs greatly from all 
the Eunice in its habits and haunts, frequenting not the forest, but 
swampy meadows, where both sexes fly slowly about low bushes. 
38. Libythina Cuvierii, Godart, Enc. Méth. ix. 171. 6. 
Eunica Hyperipte, Hibn. Samml. Ex. Schm. 
Found, in the Amazons region, only in the neighbourhood of San- 
tarem and on the shores of the Lower Tapajos. 
Genus Eprcata (Boisd.), Westwood, in D. & H. Gen. Di. Lep. p. 256. 
This genus is very closely allied to Hunica, differing in structure 
only by the absence of inflation of the fore-wing nervures at their 
bases, and by the lower disco-cellular of the fore wing joining the 
median at a distance from its terminal fork, instead of close to the latter. 
E. Capenas seems to be intermediate between the two groups in respect 
of the position of the lower disco-cellular. The two genera form 
.
