LIMENITIS II. 
of the mysterious packets much and patient watching has failed to discover, but 
their presence and the building up of the perches are very curious features in 
the history of these species.) Finally, part of the latest brood of the year make 
themselves cases in which to sleep away the short winter, while part go on to 
chrysalis and butterfly, as related above. So far as Dr. Wittfeld has observed, 
these cases are made after the second moult. The larvae of Disippus make cases 
both after second and third moults. 
The egg and chrysalis of Eros are precisely like those of Disippus ; the egg 
is like that of Arthemis also, and the chrysalis scarcely differs from that of the 
last-named species, except in coloration. The caterpillars also at all stages are 
of same general form and armature as those of Disippus and Artliemis , but 
after the first stage they differ from both these in some very important points. 
The coloring is essentially different at all stages after first moult, from that of 
Disippus , until maturity is reached ; that is, to the middle of the stage succeed¬ 
ing the fourth, and last, moult; and then, the two approach each other again, 
both changing color and becoming green. On the other hand, Eros is very like 
Arthemis , and still more, I apprehend, like Ursula, in coloration, and these species 
also change to green at maturity. But Eros differs remarkably from the two 
first-named species ( Ursula I have never bred), in the length, shape, and color 
and armature of the appendages on third segment. 
Mrs. Peart, who was making drawings of the larval stages of Eros and Disip¬ 
pus at same time, and had occasion to remark all the minor points, informs me 
that the grains on the dorsal tubercles and processes of Eros are both larger and 
in greater number than in Disippus. 
I compare the differences between the larvae in color; thus, — 
Eros , after first moult. 
Color red-brown; the appendages on 3 are .03 
inch long, tapering to top, black. 
After second moult. 
Color red-brown ; tlie appendages .05 inch long ; 
tapering, black, with separated spurs on sides. 
After third moult. 
Color deep red, or ferruginous, the anterior 
segments and dorsal patch red-buff; the appendages 
from .11 to .16 inch long, black, slender, taper¬ 
ing from base to top, bent forward near top, with 
scattered spurs over sides, which spurs are black, 
the tips tawny. 
Disippus , after first moult. 
Color mottled tawny and dark (not red) brown ; 
the appendages on 3 are .01 inch long, merely 
tubercles, with cluster of grains (as in Arthemis 
Plate, Fig. c 2 ), some of these white, some black. 
After second moult. 
Color more black, less tawny ; the appendages 
.03 inch long, thick, club-shaped, covered closely 
with grains, mostly tawny, a few black (as in Ar¬ 
themis, Plate, fig. d.). 
After third summer moult. 
Color black, the tops of all tubercles tawny ; 
the appendages .06 to .08 inch long, clubbed, as 
before, tawny.
