ANTENNA the length of the thorax, pectinated in- 

 ternally ; two distinct, three jointed palpi ; and the 

 size of the upper wings, which are much larger than 

 the under pair, afford marks sufficient to distinguish 

 this conspicuous genus. The figure referred to re- 

 presents the only species known 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 brown, and marked 

 with numerous narrow black streaks, which are 

 waved and frequently cross each other, forming irre- 

 gular meshes ; hinder wings brown, with faint re- 

 ticular streaks posteriorly. The head and back of 

 the thorax are brown, the latter ochre-yellow in 

 front and whitish behind, with a transverse band 

 of black ; the abdomen brown, each segment bor- 

 dered behind with greyish- white.
