scries of smoky faint venular spots, as well as the double discal dots on tlic 

 under side, one of which faintly reappears on the upper side of both pairs 

 of wings. 



Although the spotted forms which I had regarded as distinct from M. 

 GueneVs herminiata do not agree with his description, as he only mentions 

 the two black discal spots on the under side of the wings, I am inclined to 

 unite biseriaia with lierminiata, as two specimens of the latter in my possession 

 agree exactly in other respects with M. Gucnec's description of herminiata, 

 and D. rariolaria is sometimes entirely white on the wings. I am also inclined 

 to regard Gucnce's albata as a variety of herminiata.

Head with a square front; the palpi a little larger than in Corycia, and 

 extending a little beyond the front; third joint a little longer than broad, 

 pointed. Male antennae well pectinated nearly to the tips; in female, simple. 

 Apex of lore wings as well as that of the hind wings inclined to be somewhat 

 produced, and there is a slight angle in the outer edge of the fore and 

 hind wings. Venation much as in Corycia, but the first subcostal is farther 

 from the costal, and less sinuous than in Corycia; while the second subcostal 

 arises half-way between the origin of the third and filth subcbetal venules, 

 much as in Acidalia. The posterior discal venule is oblique, as in Corycia. 

 Hind legs with the tibiae not much swollen, the tarsi nearly as long as the 

 tibiae. Coloration: the wings white or cchreous, with two parallel ochreous 

 diffuse lines, more or less distinct, common to both wings, and usually a basal 

 line on the fore wings. 



The species are distinguished from Corycia by the pectinated antennae, 

 the two common lines, and the generally ochreous tint, though the females 

 of variolaria are with difficulty separated from those of Corycia. From 

 Acidalia, it differs in the pectinated antennae, the want of a decided band in 

 the hind wing:-., and the larger palpi.
