212 RHOPALOCERA. 
E. dione have a very wide range over the southern continent; and E. godmant and 
E. kefersteini are found in Colombia and Venezuela. 
The genital armature of the male is rather peculiar in being much compressed ; the 
tegumen is strongly developed, and the central spine is long and stout: the harpagones 
are feeble: those of E. lethe are two-lobed, each lobe bearing a blunt spur ; those of 
E. kefersteini have a single lobe without spur, but terminated with hairs. 
The palpi are slightly hairy, the terminal joint being rather stout and about one 
third the middle joint, which is slender and but slightly swollen. The antenne have 
37 joints, whereof the terminal 10 form a moderate club, the last joint being blunt. 
The front legs of the male are hairy and slightly scaled; coxa > 4 femur-+ trochanter ; 
tibia=femur ; tarsus (suture of a joint just visible)=% tibia. Claws of the other legs 
much curved, paronychia nearly straight, pulvillus very large. The costa of the 
_ primaries is in a simple curve; the first and second subcostal branches are thrown off 
before the end of the cell, the third some distance beyond it; the upper discocellular 
is very short, and the middle about half the lower, which is well developed. The 
precostal nervure of the secondaries is nearly straight, and stands about at right angles 
to the costal. 
a. Primary wings without hyaline spots; outer margin of secondaries produced 
so as to form a slight tail. .

A common and widely ranging butterfly, which is found throughout our region, and 
just passes the northern frontier into Texas?. In Guatemala it has a mountain range 
as high as about 4000 feet at Purula, but the low-lying lands are its home. 
This species is very constant in its markings. Notwithstanding its range, we 
are unable to trace any noteworthy difference between Mexican and Paraguayan 
specimens.
