joins to a streak about three-fourths of an inch long, running from these edges towards the centre of the 

 wing, near to which is placed two darkish round spots. Posterior wings having a row of dark crescents 

 placed along the external edges, which becomes double near the abdominal corners ; and a row of faint 

 whiteish streaks crossing them from the anterior to the abdominal edges, meeting about an inch below 

 the body. 



Under Side. Palpi, legs, breast, and abdomen white. Wings coloured as on the upper side. The two 

 round spots on the anterior ones are black ; and the row of faint-coloured streaks crossing the posterior 

 ones are here very strong ; each streak being white, and placed on a brown ground, edged with yellow. 

 Margins of the wings slightly dentated. 



Fabricius, in the Entomologia Systematica, described two butterflies under the name of 

 Papilio (N.) Laertes, No. 226. from Surinam figured by Cramer, and No. 262, from South 

 America, figured by Drury. As the former species had the priority in point of date, 

 Fabricius, in the alphabetical index to that work, altered the name of Drury's insect to 

 Epistrophus. By the establishment, however, of the genus Morpho, comprising the insect 

 figured by Drury, the difficulty is obviated, and as the species is universally knowTi under 

 the name of Laertes, it does not appear requisite to adopt the name of Epistrophus.
