Walsingham. 
Characters. — Head smooth; ocelli rather large, posterior; tongue developed. Antennae 5/6, 
in G' simple, basal joint moderately elongate, without pecten. Labial palpi long, recurved, second joint 
smooth-scaled, compressed, terminal joint as long as second, slender, acute. Maxillary palpi rudimentary. 
Posterior tibiae more or less rough-scaled above. Forewings with 15 furcate, 2 and 3 stalked, 7 absent, 
11 from beyond middle. Hindwings nearly r, trapezoidal, termen slightly sinuate, cilia 2/3-1; with 
cubital pecten; 3 and 4 connate or short-stalked, 5 somewhat approximated, 6 and 7 closely approximated 
at base. 
Remarks. — The imagos are described as restless, turning in circles on leaves in shaded places, 
a habit probably shared by the nearly allied genera, which are characterised by bright blue-metallic or 
silvery markings, apparently adapted for display.
