282 Lloyd's natural history. 



The East Indian species, O. erithonius (Cramer), has the 

 central band much broader and more irregular, especially on 

 the hind-wings, where the eye-spot on the costa is very slightly 

 marked, and that on the inner-margin has become a large red 

 spot. 



[xLi.] This genus has not yet received a name. It includes 

 some handsome West Indian tailed Butterflies, among which is 

 Papilio hofjieriis, Fabricius, a very local Butterfly in Jamaica, and 

 one of the largest of all the American Equi/id(C, expanding 5^2 

 or 6 inches. It is black, with a very broad yellow band on all 

 the wings, bifld towards the costa of the fore-wings. The 

 fore-wings have two or three yellow spots towards the tip ; and 

 beyond the yellow band on the hind-wings is an outer row of 

 blue dusting, and some orange-red sub-marginal lunules. 



[xlil] Heraclides^ Hiibner. This is another genus peculiar 

 to America. It includes large and handsome Butterflies, 

 measuring from four to six inches across the wings. The type is 

 H. thoas (Linn.). The fore-wings are rather long and pointed, 

 the hind-margin being slightly concave, as well as oblique, and 

 the hind-wings are strongly dentated, with a broad spatulate 

 tail. The wings are black, with a broad yellow band, more or 

 less macular, at least on the fore-wings, where it often bifurcates 

 towards the costa, and broadest on the inner-margin of the 

 hind-wings. The hind-wings have a curved row of yellow 

 lunules on the disc, followed by a more or less distinct black, 

 blue, and red eye-spot towards the inner-margin \ the tail is 

 ofien streaked with yellow. On the under side the yellow 

 markings are more extended, and the principal black band on 

 the hind-wings is marked with blue and reddish crescents. 

 The larva of H. crcsphontes (Cramer), the common North 

 American species, in which the yellow band is narrower and 

 more broken into spots than in the Southern species of the 

 genus, feevls on orange, like so many of the American Equitidce.
