9 S . — A mutdi smallei', less pilose species than the Mnropean /'. jularia, 

 with the pectinations of the antenna' mutdi shorter. Pale ash with hlaekish- 

 hrown specks and lines Head while on the vertex, iirown on the front. 

 Thorax whitish with a hlack eoUai-, not extending, however, to the base ot' the 

 wings. Two rows of lilack spots along the ahdonieii. Fore wini^s pale ash, 

 speckled with dark l)rown : three blackish lines, the two inner ])arallel, the

 the two outer lines on tin' hind edge of the lore wiiiirs, in some the two 

 touching each other on the edge of the win<r. It dillers from Aiil.wpteri/x
