H. Astydamia of Erichson differs from the type in wanting the radiating lines of the 
hind wing. We have already seen that this is a common form of aberration in the 
Heliconii of this group. .

A common and well-known species. It appears to he distributed throughout the 
whole of the northern part of tropical America. It differs in habits from the other 
species of the genus, inasmuch as it frequents the skirts of woods, semicultivated 
grounds, and gardens. Its antennae are short, and strongly clavate : in this feature, as 
well, indeed, as in size, shape, and habits, it approaches the genus Eueides.

Papilio Isabella Nereis fulva Dianasa, Hiibn. Samml. Exot. Schm. (slight var.). 
This is a common and abundant species throughout the Amazon region It does not 
inhabit the forest, but frequents open bushy places on the skirts of woods, flying in the 
usual sailing manner of the Heliconii. like the species of Heliconida? which have the 
same style of coloration {Heliconius Numata, Mechanitis JPolymnia, &c.)» it is a variable 
insect on the Upper Amazons, although constant in its specific characters at Para. H. 
Dianasa of Hiibner is a slight variety.

Ega, rare. Although very closely allied to Eu. Isabella, this is a well-marked form, 
which probably maintains itself distinct from that species. It differs somewhat in the 
shape of the wings ; the pale central crossbelt is divided into separate spots ; the 
antennge are black, with the club pale beneath. It is an approximation towards Eu. 
Cleobaa (Hiibn.) of Mexico.

2 3". Fore wing broader, the costa more arched than in Eu. Isabella : above, orange- 
tawny ; a small portion at the apex, a narrow outer margin, and a broad stripe near the 
hind margin, extending from the base to near the hind angle, black ; there are also four 
black spots on the disk, viz. a large wedge-shaped spot within the cell near the base, a 
small one over the disco-cellulars, a large rounded one between the 2nd and 3rd, and an 
indistinct one between the 1st and 2nd median branches; close to the apex are two 
whitish spots. Beneath, the same, except that there are three white apical spots. 
Hind wing : above, orange-tawny ; a line along the basal half of the subcostal nervure, 
a broad central stripe of six elongate spots behind the cell, and a broad hind border
