(Argynnis Lathonia), 
ARGYNNIS ADIPPE (the High-brown Fritillary) strongly resembles, at the first glance, the 
last described species, A. Aglaia, but a closer examination enables the observer to detect the 
more angular character of the black markings. The colour also is different, being of a more 
orange tawny tone, which is the same in both sexes; the female being, however, rather paler, 
and larger in size, while the male is distinguished by thickening of the three posterior veins of 
the front wings. On the under side (No. 2), it may be distinguished at once from Aglaia by 
the absence of the rich green from the hind wings, which are only varied with tones of buff 
and brown, and nearly alike in both sexes. 
The Caterpillar (No. 3) is, when young, red underneath, but in its later stages assumes an 
olive green colour. It feeds on the Heartsease and Violet, on the foliage of which it should be 
sought in May and early in June. 
The Chrysalis is reddish brown with silver specks, and the perfect insect appears in June 
- and July, in woods, and also on heaths. It is much less common than 4. Aglaia, but has been 
taken recently in some abundance at Lyndhurst, at York, and in other northern districts, 
though it was formerly considered to be almost exclusively confined to the southern counties, 
where, in fact, it is still found more generally distributed than in the north. There are varieties, 
as in the preceding species, in which the black markings run into each other, giving the wings 
a darker appearance. 
Argynnis Lathonia (the Queen of Spain Fritillary, No. 4) is by far the rarest of our large 
British Fritillaries, and is in some respects the handsomest, though far inferior in size to the 
three species previously described. 
The males may be distinguished by the dilation of the posterior nervures of the front wings ; 
in other respects the colouring and markings are alike, or very nearly so, in both sexes, 
The under side (shown at No. 5) has the pearly patches more symmetrically distributed 
than in any of the other species, and of a more brilliant character, both as to their gloss and 
their more metallic appearance. In some Continental specimens which I have seen, these mark- 
ings are enlarged so as to cover the whole of the surface of the hind wings, which thus assume 
the aspect of a burnished plate of silver, marked at intervals with dark streaks formed by the 
nervures. 
The Caterpillar feeds on the Borage, and also on Heartsease and Violet. There are said to 
be two broods, one most probably appearing in April or early in May, the other in July.
