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



n. Asti/ddmid 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 

 Ileliconii of this group.

A common and well-known species. It appears to be distriljuted througliout 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 antcnnte are short, and strongly clavate : in this feature, as 

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

This is a common and abundant species throughout the Amazon region It does not 

 inhal)it the forest, but frequents open bushy places on the skirts of woods, flying in the 

 usual sailing manner of the Helicoiiii. Lilvc the species oi Helicon idee which have the 

 same style of coloration {Htdiconins Niimata, Mefdniuitis Foli/miiia, &c.), it is a variable 

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

 Dianasa of Iluljucr is a slight variety.

Ijga, rare. Although very closely allied to En. IsabrUa, this is a well-marked form, 

 which prol)ably 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 

 antenna^ are black, with the club pale beneath. It is an approximation towards Ek. 

 Cleohd'a (llubn.) of ]\[exico.

+ o". lu>r(' loing broader, the costa more arched than in En. Isabella : above, orange- 

 inwiiy ; a small portion at the apex, a narrow outer margin, and a broad stripe near the 

 hind margin, extending from tin; base to near tlu^ hind angle, black; there are also four 

 black spots on the disk, viz. a largo wedge-sliapcd spot within the cell near the base, a 

 small o]io over the disco-cellulars, a large rounded f)ne between the 2nd and 3rd, and an 

 indistinct one 1)etweon the 1st and 2n(l median branches; close to the apex ai'c two 

 uliitisb spols. licncalli, the same, ('\(r[)t that there are three white apical spots.
