 ered l)y a delicate iiieiidiraiie which is usually lelt in the I'ollicit' 

 in removing the scale. Tiie shaft ol' tlie scale is lilled with medul- 

 lary substance resemhling that of the human hair, and towards the 

 l)road expanded part of the scales this medullary sul)stance separates 

 and runs into the tiliments. In the body of the scales are a num- 

 ber of pigment cells.. 



'^riie hairs at the base of the wing are inserted in the same wav 

 and are a})parcntly of the same structnre as of tht long cells, but 

 bifurcate at one fifth of the distance of their length. The scales on 

 the veins of the wings ai'c com[)act and thick and resemble those on 

 the fringe, but are much longer and have more pigment ])atches. 



The scales on the body magnified to 050 diameters are covered 

 with nnmerons lines of e<iual distances apart with sjiaces of the 

 width of each line intervening, and these lines are apparently tubes 

 filled with medullary substances all connecting at or near tlie stem. 

 Those on the body have numerous patches of pigment cells.

 more continuous, subterminal shade across the fore wings. TIu' foi-e 

 wings are a bright Idackish gray, like the darkest gray relida: with- 

 out any admixture of ochery or brown. Anterior line dentate, filled 

 with white. Snbreniform white, free from the onter line ; a white 

 shade on the cell before the reniform which is edged with white. 

 Sul)terminal space wider than in brisi^is, white. Posterior line more 

 dentate than in hri.^eis. Fringes tipped with white. Secondaries 

 bright pink, lighter and gayer colored than brisels. ^fedian band 

 tolorably even, abbreviate. IS'o dark scales at base or along internal 

 margin. Fringes white. Thorax dark gray. Beneath much as in /jriscis, 

 bid the median fascia on hind wings does not reach the margin. This 

 form seems larger than lin'seis and expands three and one eighth 

 inches. ]\[y s})ecimen is a S iii good condition and was taken in
