and thorax bluish Avhite, liberally sprinkled with black and dark fus- 

 cous scales. Forewing-s elongate slender, apex deflexed; g-round 

 color bluish white, but so thickW overlaid with black and fuscous as 

 to appear dark, each scale being mottled with white and black or dark 

 fuscous. On the basal and apical one-third the light color prevails so 

 as to make these parts light pearl gray to the naked eve; the middle 

 part of the wing appears without a lens blackish, but under a lens is 

 disclosed the composite coloration. On the middle of the cell is a 

 short deep black perpendicular dash slightly edged with brown scales; 

 at the end of the cell is another similar larger oblique velvety black 

 dash, also edged with light brown. Parallel with the dorsal edg-e and 

 just within this is a row of three equidistant large tufts of erect scales. 

 Hindwings dark fuscous, cilia a shade lighter. First two abdominal 

 segments are light ochreous above, rest of abdomen light irridescent 

 gray; legs light gray on the inside, black on the outside; tarsal joints 

 slightly tipped with white.

Type of this easily recognized species is found in the Museum of 

 Comparative Zoology, where J have examined it and compared it with 

 an identical specimen from Las Vegas, New Mexico, belonging to the 

 National Museum. 



1 have also examined and received identical specimens from Dr. 

 Dietz, collected at Denver, Colorado, from where Chambers' type came. 



This species represent the extreme development of the genus, hav- 

 ing the distinguishing palpal characters accentuated, as described l>y 

 Chambers.
