VAEIETY. 
Caucasica, Stauclinger, Cat. p. 21. — Larger than the type, 
the male lighter. 
Habitat. — Armenia and Turkey. 
16.* — A. Lathonia (rect. Laionia), Linn. Syst. Nat. x. 481; Faun. 
Suec. 282; Esp. 18, 2; Hiih. 59, 60; 0. I. 1, 80; 
Fit. 13, 25. 
Expands from 1-80 to 2.15 in. Hind margin of fore wings 
distinctly concave; hind wings dentate, less rounded in outline than 
in the other species. All the wings bright fulvous, with distinctly 
rounded black spots, two rows running parallel to the hind mar- 
gins ; the base is blackish. Under side : Fore wings yellowish, 
with black spots, and with several silvery spots at the apex ; hind 
wings fulvous, inclining to yellow, with a row of large oval silvery 
spots placed parallel to the margins ; internal to these is a row of 
reddish brown spots, each enclosing a central silvery dot; there are 
large basal and central silvery spots, more or less oval in shape, 
and very brilliant. PI. XLIX., 2. 
Time op Appearance. — May to September. 
Habitat. — The whole Palsearctic territory, excepting the Polar 
and Higher Alpine Piegions — that is, all Temperate Europe and 
North Asia, North Africa, Persia, &c. It is rare in Britain, 
occurring principally in the South of England. It inhabits woods, 
meadows, roadsides, gardens, &c., and is generally common. 
Larva. — Greyish brown, with a white dorsal line. It has sixty 
spines, four on the first and last segments and six on each of the 
others, those of the first two are shorter than the rest, the central 
ones being the longest. Feeds solitarily on Viola tricolor and Ono- 
brychis in May and August. 
Pupa. — Grey anteriorly, green posteriorly, with gold spots. 
* The statement on p. 195 that the genus Argynnis only occurs in the 
Nearctic and Patearctic Eegions requires some modification, since one if not two 
species occur in Chili which are closely allied to A. Lathonia; another species 
also occurs in Buenos Ayres. Some zoologists, however, consider the temperate 
portion of South America to form part of a region which includes the Palasarctic 
and Nearctic Eegions of Wallace, &c.
