INTRODUCTION. 
This specimen of a Catalogue of Butterflies of the family Lyccenidce includes the 
description of those of the genus Amhlypodia chiefly ; not only of such as are in the 
f 
British Museum, but of some examples representing species not there, and known to 
be in other collections, with the view of indicating desiderata for the National Museum 
to persons who may have the opportunity and disposition to supply them. 
Mr. Hewitson observes : — Beeling the impossibility of pointing out satisfactorily, 
by description only, the nice distinctions which characterize the species of the genus 
Amhlypodia, figm^es of every new or undescribed species have been given. 
‘‘ Bor this reason the author has not attempted to describe each species in detail. 
On the upper surface, with two or three exceptions, they are of a blue (varying 
infinitely in tint), sometimes intense, sometimes of the lustre almost of Morpho 
Oypris and M. Ulietenor. On the underside, where almost every species has a cer- 
tain number of spots near the base of both wings, as well as at the end of the discoidal 
cell, their absence only has been noticed in the descriptions ; whilst the form of the 
band which crosses the anterior wing, and is one of the most distinctive charac- 
teristics of the group, has been particularly referred to. In consequence of expe- 
rience gained during the progress of the work, two or three alterations have been 
made in the nomenclature of the plates. 
“Bare and unique species have, with much liberality and kindness, been lent 
[to make this specimen of a Catalogue more complete] from the collections of 
Dr. Boisduval, the East India Museum, from Mr. Wallace, Mr. Saunders, Dr. Eelder 
of Vienna, and the Hope Museum at Oxford.” 
The figures of the new species are from Mr, Hewitson’ s pencil, and have been 
coloured under his superintendence by Mr. Standish.
