Imago. — Head with, usual small tuft of hairs close to origin of each 
antenna : 2^^h^^ lo^ig? — the second joint densely hairy, — the third 
long, ascendant or erect, or horizontally porrected, clothed with short 
appressed hairs ; anUnnce short, with a gradually-formed sub-cylindrical 
club, thinner and slightly curved towards tip (which is blunt). 
Thorax robust and hairy. Wings with neuration as in Pamphila, 
Fab. Fore-wings more or less pointed apically ; discoidal cell about 
three-fifths the length of the wing, its very slender closing nervules 
forming an inwardly oblique line ; ^ in some species with a lower 
discal linear groove running obliquely from second median nervule near 
its origin to submedian nervure before middle. Hind-ioings small, 
bluntly rounded, usually rather prominent (sometimes much so) anal- 
angularly ; discoidal cell very short, from one-third to less than half 
the length of the wing, — its closing nervule angulated inwardly in the 
middle. Legs rather short and thick ; femora (especially hind ones 
superiorly) more or less hairy ; appendage to tibiae of first pair incon- 
spicuous, often with difficulty perceptible among the scaly hairs ; tarsi 
spinulose beneath. 
Abdomen rather long, — in $ laterally compressed and slightly tufted 
at extremity. 
Larva. — Slender, gradually attenuated anteriorly, rather abruptly 
pointed posteriorly ; head small ; no hairs on tubercles. 
Pupa. — Slender and elongate ; frontal spike of head short ; ex- 
tremity of abdomen very attenuated and acute ; case of haustellum 
extending freely to about half the length of abdomen. 
(These characters are those of the early stages of Thaumas (Linea) 
and Lineola (European species), as figured and described by Hiibner, 
Duponchel, and Boisduval.) 
There is little to distinguish this genus from Pamphila, Fab., 
except the blunt unhooked club of the antennae, and the much longer 
and usually more erect terminal joint of the palpi. In the former
