INTRODUCTION. V 
At the commencement of the work, I expressed an opmion that the butterflies 
which formed the genera of Epicalia and Myscelia, were near enough to form one 
genus. ‘They have since proved to be the sexes of the same species. Myscelia 
Samaria of the plate is the female of Epicalia Sabrina of the same plate. 
Epicalia Pierreti (Pl. 29) and Myscelia Chromis (27), both of the “ Genera of 
Diurnal Lep.,” are male and female of the same species. 
Epicalia Numilius (Cram., Pl. 81) and Myscelia Micalia (P. Mic., Cram., Pl. 108) 
are sexes of one species, and I believe that Epicalia Autinoe Godt, is the male of 
Hpicalia Penthia of this work. 
Although great care has been taken by Mr. Standish with the Plates, some of 
the delicate Ithomias of Plate VII. are rather too highly coloured; figs. 38, 39, and 
40, are sometimes quite white. 
N.B.—An Index is given, by which the binder will be enabled to arrange the 
Plates, as in the “ Genera of Diurnal Lepidoptera.” 
A second Index, alphabetically arranged, is given for the benefit of those who 
will take the trouble to number the Plates (from 1 to 60), and the letterpress (from 
1 to 120), after the book has been arranged by the first Index.
