mesial vein, then bends sharply outward to vein 3, then inward to vein 2, 

 then outward to inner margin, where it ends in . a large black blotch. 

 Mesial space light ash with reddish shading, discal spot small, black and 

 linear. The mesial band is narrower than any of the other species, not more 

 than 3 mm. in widest portion. Outer black line of mesial space bends 

 sharply outward from costa to vein 7, then sharply inward towards discal 

 point, sending a black streak almost to it, from which it doubles back 

 towards outer margin in two scallops to vein 3, whence it runs almost 

 straight to inner margin, ending in a black spot. The usual smoke- 

 coloured irregular band between this line and outer margin, beyond which 

 the wing is clear, except for intervenular spots, also the usual black apical 

 streak ; fringe short and light ash-coloured. Hind wings pale ash, discal 

 spots showing plainly. The inner characteristic line of this group showing 

 in dots on veins which is rather unusual, the outer pale line being normal. 

 Beneath, fore wings pale ash, and showing same markings as above, 

 except that the extradiscal line shows quite plainly at costa as a black 

 patch, discal points visible on fore and hind wings. Hind wings light ash, 

 inner band showing in dots on vein as above. 



Types, 2 <$ 's, Huachuca and Chiricahua Mts., Arizona, from Dr. 

 Barnes. 



This species may be known by the peculiar narrow mesial band, the 

 course of third line, and three black patches on inner margin and by the 

 dotted line on hind wing. 



Hydriomena Edenata, n. sp. — Expanse, 30-34 mm.; palpi long, 2 

 mm., rather bushy, black scaled ; front of head yellowish-ash ; thorax and 

 abdomen light ash. Antennae minutely ringed with white. Fore wings 

 long and narrow, ash-gray, with rust-red shadings in mesial band and outer 

 border. Base of wing clear ash. There is no basal line as in ruberata, 

 European or North American forms. At a distance out from the body 

 the first black line of mesial band starts from the costa, diagonally across 

 wing to inner margin, with a slight bend outwards at median vein, which 

 is shaded with red. Next the usual wide irregular bluish band from costa 

 to inner margin, shaded outwardly with red ; the third line is almost 

 thread-like, and runs zigzag on each vein from costa to inner margin. 

 From this line on inner margin to the first line there extends across the 

 entire mesial band a wide black bar, which is extremely striking. The 

 mesial space is pale ash tinged with red, with a black linear discal spot. 

 The extradiscal line is black and narrow, runs outward to apical dash, 

 then inward, forming a sharp-pointed tooth, bending outward to median
