Antennas the length of the thorax, pectinated in- 
ternally ; two distinct, three jointed palpi ; and the 
size of the upper wings, which ai'e much larger than 
the under pair, afford marks sufficient to distinguish 
this conspicuous genus. The figure referred to re- 
presents the only species knoum to inhabit Europe. 
The expansion of the wings is from three inches to 
three inches and a half ; the colour of the superior 
pair ashy-white, clouded with broum, and maiiced 
uith niunerous narrow black streaks, which are 
waved and frequently cross each other, fonning irre- 
gular meshes j hinder wings brouTi, uith faint re- 
ticular streaks posteriorly. Tlie head and back of 
the thorax are brovrn, the latter ochre-yellow in 
front and whitish behind, with a trang^’erse band 
of black j the abdomen broun, each segment bor- 
dered behind with greyish- white.
