cases, to some of the numerous South American species of 

 Lyc(X7iid(c aUied to Theda. The most remarkable of all, how- 

 ever, are one or two tawny species, such as E. opakscens and 

 O. prcEclara^ of Hewitson, which are shot with a most splendid 

 and delicate mother-of-pearl iridescence, for which we may 

 seek in vain elsewhere in Butterflies, except in Ornithopfe?'a 

 magellaniiSy Felder, Morpho sulko'cvskyi^ KoUar, and in the 

 crimson spots of some of the South American Equiticles. 



According to Messrs. Godman and Salvin, "all the species 

 of this genus have the habit of resting on the under surface of 

 leaves within a few feet of the ground." 



The type is indicated by Dr. Scudder as — ■ 



EUSELASIA GELON.

A rather inconspicuous brown Butterfly, with rounded wings, 

 expanding about an inch. There is a fulvous blotch towards 

 the anal angle of the hind-wings, both above and below. The 

 under surface is pale yellow, with three parallel brown lines. It 

 is found in Surinam. Dr. Scudder remarks that the larva "is 

 said by Bar to be nocturnal in habits, and processional, the 

 caterpillars following one another in a single rank; it is covered 

 with pile (velvet), and ' wholly resembles the caterpillar of a 

 small Boinbyx! The chrysalis somewhat resembles that d. 

 Theclar This processionary habit has previously only been 

 observed in the case of certain Moths {Bomhyces). 



As an illustration of this genus we have selected
