 fourth, another near the costa at the basal third, and a transverse 

 white line at the apical third of the lobe. The first lobe with a 

 dark longitudinal spot half-way between the costa and hind mar- 

 gin ; second lobe dark at the anal angle. Fringes whitish, with a 

 patch of dark scales before and another just behind the apex of

Expanse of wings, 23 mm. Head, thorax and abdomen tawny

Fore wings tawny yellow, fissure extending in about one-fourth 

 of the length of the wing ; triangular spot dark brown, its outer 

 margin slightly concave ; three dark diffuse longitudinal spots, one 

 on the basal third of the wing near the costa, one near the hind 

 margin, nearer the base than the latter, and one on the outer third 

 of the hind margin. Two paler transverse lines cross the outer 

 portion of the wing, one bordering the triangular spot behind and 

 curving across the lower lobe towards the anal angle, the other 

 very near and parallel to the outer margin. The space between 

 these two lines usually darker than the ground color. Fringes
