trunks in inaccessible positions ; but the flight is not strong or 
sustained like that of the larger Niimphaluke. The colour of the 
wings is brown, varying from light fulvous to nearly black ; the 
wings have broad submarginal bands of a lighter colour, sometimes 
white. There is always at least one ocellated spot near the apex 
of the fore wing, and generally one near the anal angle of the hind 
wing. The under side of the hind wings nearly always has a cha- 
racteristic coloration and pattern of grey and whitish blended in a 
most pleasing manner, like that seen in Satyrus Seinele (the Kock 
Underwing) ; this pattern is protective, from its assimilating to the 
objects on which the butterflies settle. The antennae are rather 
long, with distinct clubs of an elongated ovate shape, rounded at 
the apex. Palpi not longer than the head, covered with stiff hairs 
placed close together at their base, having the last articulation very 
short, conical, and more or less pointed. The eyes are smooth. 
The anterior legs are short and slender, very hirsute in the male, 
in the female more sparingly covered with hair, and have the tarsi 
single-jointed. The anterior wings are rather pointed at the apex, 
the hind margins are scarcely if at all dentate. Hind wings 
rounded, and nearly always slightly dentate along the hind 
margins. The costal nervure very much dilated at the base, the 
median sometimes very strongly, sometimes only slightly so ; the 
submedian not sensibly dilated. The males of this genus have a 
thickened patch of scales beneath the median nervure of the fore 
wings. 
This genus contains about forty known species. Europe 
proper possesses less than half of these, and they occur principally 
in the southern and south-central parts. Only one species, S. 
Semele, L., occurs in Britain, and only one or two more in the 
immediately adjoining countries. Armenia, Asia Minor, Syria, 
North Africa, and generally the more southern parts of the Palse- 
arctic region furnish many species ; several are found in the 
Himalayas, Northern India, and Japan. The Nearctic region has 
about eight species, and several more are found in Chili.
