SOME UNDESCRIBED BUTTERFLIES FROM COLOM- 

 BIA AND FROM LOWER CALIFORNIA. 



BY A. G. WEEKS, JR. 



Ithomia sarcinarius sp. nov. 



Habitat: Bogota, Colombia. Expanse: 1 .80 inches. 



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

 eyes in front. Thorax black, above, 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. 



The upper side of hind wing is transparent, distinctly yellowish in some 

 lights. The costa is black, and the hind margin has a border of black nearly 

 one quarter inch wide, covering anal angle and extending along inner margin as 

 a line only. The black of costa extends downward somewhat near end of dis- 

 coidal space. The yellow tinge of transparent portion is more apparent in the 

 basal area.
