562 MR. H. W. BATES ON THE HELICONIDE LEPIDOPTERA 



E. Astydamia of Ericlison 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 be 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, semiciiltivated 

 grounds, and gardens. Its antennse are short, and strongly clavate : in this feature, as 

 well, indeed, as in size, shape, and habits, it approaches the genus Euekles.

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, iiying in the 

 usual sailing manner of the HeUconii. Like the species of Helicomdce which have the 

 same style of coloration {Heliconius Numata, Mechanitis Folymnia, &c.), it is a variable 

 insect on the Upper Amazons, although constant in its specific characters at Para. H. 

 Bianasa of Hlibner is a slight variety.

Ega, rare. Although very closely allied to En. Isabella, this is a weU-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 

 antennse are black, with the club pale beneath. It is an approximation towards Eu. 

 Cleobcea (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
