The species shows a rather remarkable tendency to varia- 

 tion. In some specimens the defining lines are almost obso- 

 lete, the bands being defined simply by a varying depth of the 

 ground color. In some the apical oblique line is indicated 

 only by a few brown scales. In one specimen the defining 

 lines are deep velvety black and extend only from the inner 

 margin to the subcostal vein. 



L. switzeraria n. var. swettaria. 



A series of six males of the above species is remarkable in 

 having a nearly white band running through the mesial brown 

 band from costa to inner margin of the primaries. The va- 

 riety is separated on the advice of Mr. L. W. Swett, to whom 

 I dedicate it. 



Type, one male, February 21, 1912. Paratypes, three males 

 in the author's collection, two in Mr. Swett's collection, one 

 in Mr. Field's collection and two in the American Museum of 

 Natural History, New York. 



This species has many of the characters of Hydriomena, 

 and it was so placed until Mr. Swett called my attention to 

 the fact that the antennal structure threw it out of that group. 

 No genus could be found that seemed to fit, and we are not 

 sufficiently acquainted with the European genera to make sure 

 that none of them will fit, so we have decided to follow our 

 European friends and place it in a genus that will serve for 

 the present, or until a close study of related genera either 

 finds the right one or makes necessary the erection of a new 

 one. Laurcntia seems to be the nearest genus to the Hydrio- 

 uiena-like. group, so here it is placed tentatively. 



Melanolophia unipunctaria n. sp. 



Alar expanse 32 mm. Antennae of male with short blunt pectinations 

 finely ciliated beneath. Head rufous gray. Thorax darker, specklol 

 with black. Abdomen gray, speckled with black, showing dense patches 

 of black scales on some of the joints dorsally. 



Primaries white, evenly densely speckled with dark brown and 

 blackish scales. Basal line dark brown, at inner quarter gently curving 

 outward from costa to median, then straight to inner margin. A sec- 

 ond line at the half subparallel to first line, evenly dentate and zigzag. 

 A third line at about the two-thirds, starting from a heavy blackish
