and obsoletely cut with pale, distinctly on under side. Hind wings 

 pale smoky, veins marked, alike in both sexes, with white interlined 

 fringes. Thorax gray, the tuffcings tipped with ochreous. Beneath 

 whitish, with double outer lines and discal lunule on hind wings; prima- 

 ries fuscous, with indistinct open discal mark. Expansion, 45 milli- 

 metres. 



Hab. — Nevada (Dr. Bailey). 



This is a stout species, nearest to arciica, from which it may be known 

 at first sight by the gray color and the drawing-in of the transverse 

 posterior line on vein 2 to within the r.eniforra. 



Hadena devastatrix (Brace). 



A specimen sent me by Dr. Bailey from Nebraska has the primaries 

 very pale, setting off the ornamentation. It bears some resemblance to 

 my material of exuUs from Labrador. 



Hadena flava, Grote, Proc. Ent. Soc. Phila. Sept. 1874. 



The type of this species is from British Columbia. A specimen col- 

 lected by Belfrage in Texas hardly differs. Anotber ( 9 ) collected by 

 Eidings in Colorado (which I took to the British Museum, in 1867, to 

 compare) has the fore wings paler, but else seems the same species; the 

 ovipositor is exserted. I now receive from Mr. Henry Edwards a speci- 

 men of his Pseudanarta crocea, and I find it much the same as the Colo- 

 rado specimen collected by Eidings. The eyes are naked, and I do not 

 think the moth can be generically separated from Hadena, although the 

 yellow hind wings give it a very distinct appearance, to which 1 have 

 alluded in my original description. The tibiae are unarmed, and its 

 resemblance to Anarta merely lies in the yellow secondaries, which it 

 shares with cordigera. 



Dryobota opina, n. s;p. 



^9. — Eyes naked, lashed. Antennae of the male rather lengthily 

 bipectinate. Dark brown. Primaries with the median space shaded 

 with black. Claviform blackish. Orbicular spherical, filled with pale 

 powdering. Eeniform moderate, with pale interior annulus. T. p. line 

 even. Subterminal space red- brown. S. t. line preceded by a blackish 

 shade, forming interspaceal, cuneiform marks and followed by short, dark, 

 linear dashes. Fringes paler than the wing. Hind wings soiled yel- 

 lowish-white, with a mesial fuscous line, discal point, and terminal line; 

 fringes pale. Thorax obscure brownish. Beneath pale, powdered with 

 brown ; distinct discal marks and an exterior common line. Expansion, 

 30 millimetres. California {Mr. Behrens, and Mr. Henry Edwards in 

 October). 



The Bryolota californica of Dr. Behr's MSS. has hairy eyes, and had 

 been described by myself under the genus Xylomiges, to which it belongs.
