Expanse 46 rnni. Length of body 18 mm. 



The eyes are naked. The collar rounded. The thorax is pro- 

 vided with a small prothoracic tuft. The abdomen has a slight tuft 

 at the base. The markings are jagged and rough. The ground 

 color is uniform bluish-gray. The half-line is present. The exterior 

 line is simple, oblique and uneven; to it is attached a black shade line, 

 representing the claviform spot. The ordinary spots are concolorous 

 and encircled with black. Orbicular spot very small ; the reniform of 

 the usual size. The median shade is present, at first oblique, and 

 parallel with the interior line to the base of the reniform, then turn- 

 ing at right angles, and continuing parallel to the exterior line to the 

 inner margin. The exterior line is denticulate, of the usual form. 

 The subterminal line is very prominent, inwardly jagged, each tooth 

 filled with black. A series of triangular dots at the base of the 

 fringe. Posterior wings gray, with a discal dot and median line.
