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 luis observed, 

 these cases are made after the second moult. The larvfe of Dlsi2)2)us malve cases 

 both after second and third moults. 



The egg and chrysahs of Eros are precisely like those of D'ts'qynis ; 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 Dlslppus and Arthemis, 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 

 Dlslppus, 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, 

 lx)th changing color and becoming green. On the otiier 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 Dlslp>- 

 ints at same time, and had occasion to remai'k all the minor points, informs me 

 that the grains on the dorsal tubercles and processes of Ei^os are both larger and 

 in greater number than in Dlslppus. 



I compare the differences between the larva^ in color ; tlius, — 



Eros, after first moult. Disippus, after fii-st moult. 



Color reil-lirowu ; the ai)pentlages on 3 are .03 Color mottled tawny and dark (not red) lirown ; 

 inch long, tapering to top, black. the appendages ou 3 are .01 inch long, merely 



tul)ercles, with cluster of grains (as in Art/wmis 

 Plate, Fig. c^), some of these white, some black. 

 After second moult. After second moult. 



Color red-brown ; the appendages .0.5 inch long ; Color more black, less tawny ; the appendages 

 tapering, black, with separated spurs ou sides. .03 inch long, thick, club-sliaped, covered closely 



with grains, mostly tawny, a few black (as in Ar- 

 themis, Plate, fig. f/.). 

 After third moult. After third summer moult. 



Color deep red, or ferruginous, the anterior Color black, the tops of all tubercles tawny ; 



segments and dorsal patch red-butl'; the appendages the appendages .OG to .08 inch long, clubbed, as 

 from .11 to .16 inch long, black, slender, taper- before, tawoy. 

 ing from base to top, bent forward near top, with 

 scattered spurs over sides, which spurs are black, 

 the tips tawny.
