PLATE XVIII. 



bod y in P. Acamas is dark brown above and pale beneath : in P. 

 Laodocus, on the contrary, the body beneath as well as above is 

 black, with a longitudinal line each side the body. 



We have been thus minute in pointing out precisely the diffe- 

 rences that prevail between these two Papiliones, from a persuasion 

 that they might perhaps be otherwise confounded together, either 

 as the same species, or as varieties of each other. There is assuredly 

 a general approximation in the appearance of those two insects, 

 although they prove so very distinct upon a close and attentive 

 comparison. 



Papilio Acamas is a native of Jamaica: Papilio Laodocus of 

 South America. A fijjure of P. Laodocus occurs in the v/ork of 

 Cramer, under the name of Papilio Glaucus.
