species is there any doubt as to the group in which they naturally 

 fall, and I have in a sort of a way made Hydriomena the refuge of 

 species whose $ I have not seen, and whose exact reference cannot 

 therefore be given. The species under it are yet in i-espect to palpi, 

 antennae, thoracic tuftings, and the position of vein (> of fore wings 

 very variable, but I hesitate to make any further divisions, as the 

 bulk of species lie midway between the extremes. Trifasciata, the 

 type of Hydriomena, has very long palpi, and is in some other re- 

 spects rather an extreme species.

H. !i>iiiiiliiri!i« n. sj). — Expauds 28-31 mm. Palpi blackish firay ; front dark 

 gray; thorax same color with more of gray, with a posterior tufting blackish at 

 end. Abdomen fuscous; fore wings base gray, mixed with scattered black scales, 

 limited by a black line somewhat oblique, angled at cell, then a broad band of 

 blackish, lightened with gray scales which run in the form of two narrow broad 

 cross-lines; this band reaches only to the discal point, the outer limiting black 

 line i)assing through the discal point rounding out to it from costa thence in- 

 wardly to below cell, then outwardly to inner margin ; then comes a compara- 

 tively narrow grayish band, not distinctly limited outwardly, having near its 

 outer edge the outer black cross-line which is wavy dentate, with its two most 

 prominent and equal protuberances between veins 2 and 3 and 3 and 4 ; outer 

 space dark, much liglitened behind middle, and with two or three subapical 

 black daslies ; hind wings light fuscous; all margins blackish ; beneath, color of 

 bind wings above, on fore wings darker along costa and outwardly towanls apex"
