6 . ? . — Head brown, a few scattered reddish hairs on the vertex. 

 Palpi brown, slightly red at base and beneath. Antennae whitish. 

 Prothorax brown, edged behind with red, and in front margiiied with 

 white. Patagia brown, white iti front and on the outer edge. Thorax 

 brown, reddish orange behind. Abdomen orange-vermillion with four 

 or five transverse black dorsal spots. Femora reddish, remainder of 

 the legs brown. 



Primaries coffee brown, marked with creamy white as follows : A 

 large basal patch, enclosing a brown patch on the costa, and a smaller 

 dot below the median vein. The basal patch is produced into a longi- 

 tudinal streak below the median vein, which is sometimes connected 

 with the transverse band. This band originates on the inner margin, 

 two-thirds from the base of the wing, runs somewhat parallel with the 

 outer margin to the second median nervule, and is thence sharply 

 angulated backward to the costa. Outside this band is the usual Arctian 

 marking, arising at the inner angle and running direct to the angle in 

 the transverse band, thence, nearly parallel with the costa, to near the 

 outer margin, thence backward at an acute angle, thence at right angles, 

 terminating on the costa midway between the apex and the transverse 

 band. There are, in addition, two spots on the costa, between the basal 

 patch and transverse band, sometimes produced into more or less com- 

 plete transverse bands, but not passing the longitudinal streak. Fringes 

 brown.
