Others are quite unlike these ; the head case and mesonotum are 

 yellow brown, and the rest of the dorsal side is j'ellow-brown with a pink 

 tint ; the stripe and the ridge brown ; the dorsal spots blue, and dull blue 

 spots below the ridge ; whole under side light yellow-brown. 



No butterflies from my larvae emerged the same season. But of four 

 chrysalids found in Florida nth to 13th Sept., 18S0, two gave butteirflies 

 25th and 27th Sept., and two over-wintered, the butterflies emerging 2nd 

 and 3rd Feb. 



I received 24th August, 1S80, from Dr. Wm. Wissfeld, Indian 

 River, Fla., about a dozen larvge of Palamedes in ist and 2nd 

 stages. My correspondent wrote: "On 15th I confined 2 !j^ in bag over 

 limb of Persea Carolina, or Red Bay. One began to lay eggs within a 

 short time, and in an hour had laid 26. The other was heavy with eggs 

 but would not lay till to-day, and has laid 7 eggs." These were sent me 

 with leaves of the food plant, in a tin box per mail, and I received them 

 24th, the leaves still fresh, and the larvae, which had hatched on the road, 

 feeding. As this food plant is not found here I tried the larvae with 

 leaves of orange and lemon, to no purpose. But sassafras they took to 

 at once. This is the food plant of P. Troihis, a species belonging to 

 same sub-group as Palamedes. I had no difficulty in raising the larvse to 

 chrysalis. They are sluggish, like the larvse of Troihis, and in general 

 behave in same way, at all stages resting on a lining of silk which they 

 had spun on middle of the leaf, whereby the leaf is curled or drawn 

 together so as to afford a concealment. This they. rarely leave, and then 

 only when hungry, feeding on the end of the leaf until it becomes too 

 small for a hiding place, after which they betake themselves to another 

 leaf. But these larvae do not cut into the side of the leaf and fold down 

 the cut portion, as Troihis does. This Dr. Wissfeld states in reply to my 

 inquiries. He farther says : " Pala?nedes roosts on the highest tree it can 

 find, oak or palmetto. I have seen four to six near sundown fluttering 

 about the tree, where they finally settled and remained. Sometimes three 

 or four so roost on one large palmetto leaf"

 amateur Entomologist with despair, when he first makes the acquaintance
