ILLUSTRATIONS OF UNFIGURED LEPIDOPTERA. 13 



hind marginal white spots are more prominent, and there is a third one at the 

 end of the lowest submedian interspace. 



The under side of hind wing is the same as upper surface, ^except that the 

 three hind marginal spots of the under side of fore wing are repeated. 



This species is not in the larger collections of this country, nor in 

 the British Museum. 

 Taken in September, 1899. 



Mesene rochesteri A. G. Weeks, Jr. 1 



(Plate VIII, Figure 2.) 

 Habitat : Suapure, Venezuela. Expanse : .90 inch. 



Head black. Antennae black, with minute white annulations at base of each 

 joint. Club black with orange tip. Thorax black above, with orange hairs, 

 beneath grayish. Abdomen orange above, beneath grayish. Legs orange above, 

 beneath grayish. 



Upper side of fore wing orange. Hind margin, apical area, and costa black. 

 This black border is nearly one quarter inch broad, covering more than half the 

 wing area. 



Upper side of hind wing orange of same shade as fore wing. The hind mar- 

 gin has a broad black border the same width as on fore wing. Costa and inner 

 margin are orange. 



Under side of fore wing the same as upper surface. 



Under side of hind wing the same as upper surface, except that the black 

 border contains two white spots, one near the anal angle, the other midway to 

 upper angle. 



Variations. In the ten specimens in my collection there is 

 scarcely any variation in the width or density of the black border. In 

 some specimens the fore wing has a white spot at the inner edge of 

 the hind marginal border, midway from apex to lower angle. The 

 two white spots on under side of hind wing sometimes show on the 

 upper surface. There is also a third spot between them. It is quite 

 probable that in a large series of specimens these white spots would 

 vary in number and development. 



It bears a close resemblance to M. eeletes. Bates, the black border 

 being, however, much broader.
