yellow spots. Beneath : same pattern as above, but the orange-tawny 
colour replaced by pale reddish-brown, changing into lilac on the disc 
of the hind-wing; a row of small whitish spots close to the outer 
border of the hind- wing. 
Table land of Guatemala, near Duenas. 
96. — Heliconius fokmosus. 
Closely resembling H. octavia, having the same elongated shape 
of fore-wing with elongated yellow spots and outer margin, destitute 
of white edging ; but the base of the fore-wing wholly blackish-brown, 
and the dark border of the hind-wing gradually increasing in width 
from the anal angle to the apex. The hind-wing beneath is of the 
same ruddy colour as above, with the exception of a lilacine stripe 
across the disc : the row of pale spots is close to the outer margin, as 
in H. octavia. 
Isthmus of Panama. 
97. — Heliconius melicerta. 
Exp. 3" 9'". Closely allied to H. sylvana (Cramer) ; but lai'ger, 
fore-wing broader, more broadly rounded at the apex, without incurvure 
of outer margin ; outer margins of all wings slightly scalloped, and 
with short white fringe in the sinuses. Black ; basal third of fore- 
wing, to the middle of cell and first median branch, orange-tawny ; to 
this succeeds a large yellow spot deeply indented in the middle of its 
outer edge, and distant from the outer margin, where (near the anal 
angle) are two or three yellow spots ; there is also a line of three yellow 
spots near the apex. In the middle of the cell is a large black sjjot, 
over the end of the cell another rather smaller spot, and between the first 
and second median branches a very small spot. The hind- wing has the 
basal half orange-tawny and the outer half black, with a yellow spot 
near the apex. Beneath : the same, except that the hind- wing has the 
base of the costa yellowish, and a series of short white marginal streaks, 
two between each nervure ; also two larger white spots near the apex 
and distant from the margin. Antennae black ; club and apical part 
of the shaft, beneath, pale tawny. 
The separation between the orange-tawny and black portions of 
the hind-wing is well defined in some examples, but rather broken in 
others, and showing, near the middle, traces of the black, discoidal, 
macular stripe, as in H. sylvana. 
Isthmus of Panama ; also found in the neighbourhood of Santa 
Martha, New Granada, whence Mr. I^ouchard recently sent home
