CYDIMON. 45 



We must notice several species of this beautiful Sub-family. 

 The typical species (C. leilus} was first figured by Madame 

 Merian, in her work on the Insects of Surinam, as early as 



1705- 



CYDIMON LEILUS. 



Papilio liilus, Linn. Syst. Nat i. p. 462, no. 25 (1758); id. 

 Mus. Ludov. Ulr. p. 206 (1764); Clerck, Icones, pi. 27,

 Lars heroicus leilaria, Hiibner, Samml. Exot. Schmett. i. pi. 



197 (1806?). 

 Leihis surinamensis, Swainson, Zool. Illustr. (2) iii pi. 125 



(1833). 



The present species, which is common in the northern parts 

 of South America, much resembles the next, but the green sub- 

 marginal markings on the hind-wings are broader, and form a 

 continuous band, here and there marked with black. The white 

 markings towards the anal angle are also more extended, and 

 the tail is almost wholly white, often with scarcely as much as 

 the line of the intersecting nervure remaining black. The 

 earlier stages are unknown, for it is not possible that the larva 

 figured by Madame Merian, with long branching spines as hard 

 as iron wire, can belong to a Cydimon, in view of Macleay's de- 

 scription and figures of the transformations of C. boisduvalii. 

 Bates describes C. leilus as flying in flocks over the tops of the 

 trees at daybreak.
