scattered points, which sometimes resolve themselves into larger 

 blotches, russet. Wings hyaline with the veins of the anterior field 

 very pale russet and of the posterior field Vandyke brown, the 

 coriaceous portion of the costal margin buffy. Limbs and ventral 

 surface pale clay color, the latter finely speckled with vandyke 

 brown and with larger paired lateral patches of the same color, the 

 former darkening in color distad, the spines tawny.

In addition to the type, we have examined six paratypes (taken 

 January 1, February 8, October 1, and December, 1910) which differ 

 little from the type. The size shows almost no variation, while color 

 differences are wholly in the degree of density of the fine brownish 

 punctations on the tegmina. In this respect the type represents one 

 pale extreme, from which the series grades to the other extreme, 

 represented by one specimen, in which these small spots are much 

 more abundant and generally distril:)uted on the tegmina, being well 

 marked on the costal field. The larger maculations of the tegmina 

 of the type are represented in the darker individuals by smaller, 

 Vandyke brown, more sharply cut ones, while the lining of the humeral 

 trunk is broader, solid, and decidedly striking.
