of the “Struggle for Existence,” our present variety, protected above its 
fellows by a closer resemblance to the distasteful Danais, might have given 
rise to a new species, and that, in less time than is generally assumed to be 
necessary for specific changes,; as this variety would be thought to present 
quite sufficient specific differences, were it brought from a distant 
region. 
In examining a number of butterflies offered for sale to the American 
Museum of Natural History, I found a curious variety of Limenitis ursula. 
Above, the markings are the same, but with the substitution of fulvous 
for blue, except in the marginal lunules, which are white with a faint 
bluish tinge. Below, the suffusion is very conspicuous and the secondaries 
in color and marking considerably resemble those of AZisippus. It is not 
impossible that the specimen may be a hybrid between these two, as I 
have seen offspring resulting from the union of such dissimilar species, as 
Smerinthus Tilie and Populi of Europe, showing the characteristics of 
both. Should the wrswda be merely a variety, it would furnish an excellent 
illustration of the way in which Jts¢ppus probably originated.

Male expands 1.3 inches. All the wings dark brown above. ‘The 
primaries throughout the middle and basal areas sparingly sprinkled with 
fulvous scales. ‘This color is deepest around the stigma, which consists of 
a velvetty black bar extending obliquely from near the middle of the 
submedian vein to the cell, and is often divided into two equal parts by 
the fourth median veinlet. A large square patch, not sprinkled with 
fulvous, occurs in the middle area at the termination of the cell; and x 
small detached yellow spot lies immediately below, and outward from the 
anterior termination of the stigma. The base and middle of the 
secondaries are covered with long yellowish hairs. Fringe on all the wings 
white. Underside fulvous, inclining to ferruginous; the internal half of 
the primaries smoky, shading into black at the base and inner margin ; 
two small yellowish spots near the centre (very distinct in some specimens, 
in others nearly obsolete) seem reproduced from above. ‘That nearest the 
apex is round, the other is larger and somewhat reniform. On the
