wing being a little less falcate. Fore wings white at base, and traversed by 

 three white zigzag lines, the basal one on the inner fourth of wing, with a 

 large angle on the submedian space, the apex of the angle filled in with a 

 few black scales, as also the outer side of the line (widest here) in the discal 

 space ; from the submedian angle is thrown out a narrow white line, running 

 through the middle of an oval ochreous patch. A longitudinal white streak 

 in the discal space, and beyond a large, lunate, transverse, white spot, the two 

 forming a very distinct exclamation-mark. Beyond, two parallel zigzag white 

 lines, the inner scalloped deeply below the first median venule ; the outer is 

 curved at the apex, and with a broad angle on the independent vein. Fringe 

 white, checkered with dark brown. Hind wings white, fringe white. 

 Beneath as above, but the hind wings are crossed by two irregular, rather 

 distinct and broad bands of ochreous with black scales, and. the base of the 

 wing is faintly peppered with dark and ochreous scales. 



Length of body, 0.66 ; of fore wing, 0.82 ; expanse of wings, 2.30 inches. 



Nevada (Edwards) ; Arizona (Dr. Palmer, from the Museum of the 

 Department of Agriculture at Washington). 



An exceedingly elegant moth, at once recognizable by the three white 

 lines, the mark of exclamation in the discal space and the narrowly-pectinated 

 antenna?. The specimen from Arizona is in bad condition, but does not 

 seem to differ from the Nevada example. 



EUASP1LATES Packard. Plate 2, fig. 2. 



This genus is intermediate in some respects between Aspilates and 

 Sterrha, with characters of its own. The head is like that of Sterrha, but 

 much fuller in front, with short palpi not projecting beyond the front. The 

 antennae are pectinated as in Sterrha, much less so than in Aspilates. The 

 fore wings are long, triangular, much produced toward the apex. The costa 

 sinuous, slightly curved in before the apex. The outer edge much longer 

 than in either of the two other genera, and very oblique. Hind wings 

 rounded, much as in Sterrha. The venation differs from Sterrha and is 

 much as in Aspilates. There is one subcostal cell and one subcostal venule 

 less than in Aspilates. Two large, unequal, stout spines on th? base of fore 

 tibiae, wanting in Sterrha and Aspilates. Legs much shorter and stouter 

 than in either of those two genera.
