Heliconius paraplesius. 
3d. Expanse 3”. Resembling H. Acde, Hiibn.; differs 
in having a yellow spot near the apex of the fore-wing, 
besides the broad belt behind the cell, and in the abdomen 
above being ringed with yellow, with the lateral spots 
elongated instead of round. 
Fore-wing black, with the basal third orange ; a large 
subquadrate spot at the end of the cell, a broad curved 
belt beyond it, consisting of seven elongate spots separated 
only by the black nervures, a triangular spot between 
the first and second median branches, and a spot near 
the apex, divided by four black nervures, all bright 
yellow. Beneath, the same. 
Hind-wing black, a stripe within the cell and seven 
lines between the radiating nervures orange; a series 
of whitish marginal specks between the ends of the 
nervures. UCostal portion of the wing deep black. Be- 
neath, the same, except that the white marginal specks 
are more distinct, two between the nervures respec- 
tively. 
Body black; head spotted with yellow, disk of the 
thorax with larger spots ; abdomen finely ringed with 
yellow, and having a row of elongate spots on each side. 
Antenne, brown, beneath and the club tawny rufous. 
Although closely resembling the common and well- 
known H. Acde, this species is most nearly allied to 
H. Xanthocles, Bates (Trans. Linn. Soc. xxi. 561), the 
two agreeing in the length but not in the colour of the 
antenne, and in the hind wing beneath presenting a 
marginal row of whitish specks. H. Xanthocles has not a 
continuous row of yellow spots on the side of the abdo- 
men. 
Olina Stalachtoides. 
@. Expanse 2” 10”. Similar in shape to O. Emilia, 
Cramer, but the wings are rather broader. 
Fore-wing above, black, with a shght bluish gloss, 
three triangular spots in the cell, an elongate spot be- 
tween the first and second median branches, a smaller 
one between the second and third, a belt of four spots 
across the apical portion of the wing, and a small spot | 
near the apex, all grayish-white, semi-transparent. Be- 
neath, the pale spots im the same position, but the apical 
spot elongated into a short belt; the black ground
