feature of the wing. Along the inner edge of the black hind marginal border, is 

 a series of very prominent interspacial white spots, running from costa, close to 

 apex, down to the lower submedian nervule. 



Upper side of hind wing has a broad hind marginal border of black one- 

 quarter inch wide. This extends from upper angle area to the lower sub- 

 median nervule, and then dwindles abruptly to a point at anal angle. In its 

 centre, downward from costa, is a series of five interspacial white spots, a con- 

 tinuance of the line of white spots of fore wing. The central portion of the 

 wing is transparent with a yellow tinge, the portion touching hind marginal 

 black area being transparent, with a blackish tinge. The nervures and nervules 

 of this transparent area are bright yellow at its centre, turning to black out- 

 ward. The anal angle and inner marginal areas are bright tawny up to the 

 lower submedian nervule. This bright tawny area is the prominent feature of 

 the coloring of the upper surface. 



The under side of both wings is the same as upper surface, except that there 

 is a dash of yellow on the costa of hind wing, running one-quarter inch upward 

 from the base. 



Taken in May, 1899. It resembles closely C. praxilla Hew. 



Ithomia sarcinarius A. G. Weeks, Jr.^ 



{Plate XXI.) 

 Habitat: Bogota, Colombia. Expanse: i. So inches. 



Head black, with a white speck behind each eye and two more between the 

 eyes in front. Thorax, above, black, with a white longitudinal dash down its 

 centre ; beneath, black, with a white speck at each shoulder. Abdomen, above, 

 black ; beneath, grayish. Antennae black, with tawny club. 



Fore wing, above, transparent, with black markings. The costa is black, the 

 black turning at apex and continuing down hind margin as a narrow border. 

 The inner marginal area, up to lower submedian nervule, is black, excepting 

 a small portion at lower angle. There is a black dash extending downward 

 from the costal black border across end of discoidal space and terminating 

 in a point in interspace below. There is also a black dash crossing the 

 centre of discoidal space. This dash is broken into a succession of three or 

 four spots. In the black border at apical area and along hind margin there is a 

 mere suggestion of interspacial white spots, but so indistinct as to be almost 

 invisible. In some lights the transparent portion of wing just below costa 

 at end of discoidal space has a yellowish dash. The median nervure also 

 appears yellowish in some lights.
