I have not thought it worth while to give both male and female of A. Adippe, as they are very similar, the male being merely a little 
smaller, of a somewhat richer colour, and having two of the nervures of the anterior wings slightly thickened. At first sight, the insect appears 
very like A. Aglaia, but, upon examination, it will be found that the markings are much more open; and on the under side the difference is 
rendered more distinct by the brown ocellated spots of the posterior wings, in which it more nearly resembles A. Lathonia, A. Lathonia is, 
however, very distinct from every other species of this genus, both by the fine regular spotting of the wings on the upper side, and also by the 
profusion of metallic marks on the under side of the posterior wings, which in some brilliant varieties taken on the Continent, form one united 
plate of silver. A. Tiathonia is from a specimen in my own possession; A. Adippe from the collection of Mr. Westwood ; and the Caterpillars 
are from Godart. H. N. H.

This exquisite insect is generally about two inches in expanse. The upper surface of the wings is fulyous- 
orange, with numerous very distinct and mostly rounded black spots; those of the apex of the fore wings 
uniting with the dark margin and inclosing several small paler buff patches. The anal and median veins are 
not dilated in the males. Beneath, the fore wings are marked nearly as above, except that the apex of the wing 
has a broad ferruginous patch, at the base of which is a silvery spot, succeeded by two small eyes, between which 
and the margin are several oval silver patches; the hind wings on this side are pale buff varied with 
reddish brown, ornamented with numerous silvery patches, varying greatly in size and form, of which there are 
about fourteen between the base of the wings, and a row of seven dark brown ocelli with silvery pupils, between 
each of which and the margin of the wing is a large silvery patch. 
The caterpillar, according to Godart, is greyish-brown, with a white dorsal line spotted with black, 
and with two brownish-yellow lines on the sides ; the spines and legs pale yellow; it feeds on heartsease, 
sainfoin, and borage. The pupa is varied with brownish and greenish, and ornamented with metallic spots. The 
perfect insect appears in August and September; but, according to Godart, the later specimens survive the 
winter, and again appear in Spring. Mr. Dale says there are two broods (Ent. Mag. i. 356). By Petiver it is 
recorded as occurring again in May ; but Mr. Stephens’ specimens captured in the middle of August were much 
faded, so that he is led to believe that the species is double-brooded. This butterfly, although still accounted a 
great rarity, occurs in numerous situations wide apart. The following are some of its localities :—Gamlingay, 
Cambridgeshire ; Stoke-by-Nayland, near Wisbeach ; Halvergate, Norfolk ; Battersea Fields, Dover, Colchester ; 
Birch Wood, Kent ; Hertford.

This species varies in the expanse of the wings from 2! to 2? inches. The upper surface is uniformly of a
