cuous only as a band bordering the middle band, broadest next the costal 

 border, the latter generally entirely obscuring the rest of 

 the basal field and sometimes quite or almost obliterating 

 the grayish band, the middle band very broad, colored 

 A more uniformly than in most of the allied species, and 

 darker in proportion to the rest of the wing than is usu- 

 ally the case in the other species, marbled with blackish 

 and grayish-fuscous, occasionally tinged slightly with ochraceous, the 

 black condensing along the borders into narrow hands, the rest of the 

 band generally nearly uniform in tint and not often deepening in color 

 from the middle ; the inner border in passing from the costal margin 

 is generally bent outwards before reaching the subcostal nervure with 

 a slight generally angular pit, and then passing the subcostal nervure 

 by but a little space is bent very deeply into a V-shaped, occasionally 

 U-shaped depression, extending nearly to the inner border, the hot. 

 tom of the depression reaching nearly, very seldom ([uite. to the origin 

 of the first median nervule ; I have one specimen where the inner 

 border crosses the wing with but a slight trace of any depression ; the 

 usual direction of the outer border may be said to be that of two nearly 

 or quite straight creuulate lines, bent upon the third median nervule 

 as far beyond the extremity of the cell as the width between the ner- 

 vules at this point, at an angle of about 85 — 90 degrees, occasionally 

 projecting into a slender tooth at this point, one end of the band strik- 

 ing the costal border at such a point that a line drawn from it at right 

 angles to the margin would strike about midway between the origin of 

 the second and third subcostal nervules, the uther striking the inner 

 border at a point as far from the tip of the first median nervule as that 

 is from the middle of the interspace between the tips of the second 

 and third median nervules ; this angle is, however, often obscured by 

 a more or less regular curve to the whole line, which again is now and 

 then indented in a similar manner to C. Oeno, but it almost invariablv 

 shows a tendency to return to this angular appearance, and the con- 

 tinuous baseward direction of the border as it approaches the costal 

 margin is quite a peculiar feature in this species. 



Beyond the middle band the wing is marbled with blackish-brown, 

 grayish-ochraceous and grayish-white, the latter almost always condensed 

 and connected next the middle band to form a band bordering it, rarely 

 tinged faintly with bluish ; sometimes the blackish-brown is condensed 

 into spots sitting upon the outer border; very seldom indistinct whitish 

 dots are present in the interspaces halfway between the middle band
