LEMONIAS I. 



poach and wild cherry. On 22d, it was evident that the cherry had been nib- 

 bkid at, but only one caterpillar was living, and that died two days later. 



On 26th July, came another lot of eggs and larva; from Mr. Doll. They had 

 been twelve days on the road, in the mail, in tin box, with Mesquit leaves. There 

 were half a dozen eggs unhatched, several caterpillars but lately out, and some 

 were in the act of emerging from round holes at the middle of the depressed 

 tops. I put these caterpillars in a glass with wild cherry leaves only, as the 

 former ones seemed to have eaten cherry a little, but in course of the next three 

 or four days one after another died, not liking the food. When but two were 

 left, I tried wild plum, giving the tenderest terminal leaves, and at last had liit 

 upon the right plant. One leaf had been dropped upside down into the glass, 

 and next day its edges were stitched to a leaf it had fallen upon, and they were 

 somewhat drawn together. Twenty-four hours later the upper leaf was quite 

 closed up, so that I had to slit one side of it to get a view of tlie tenant, which was 

 resting on the midrib, and had made for itself a thick bed of silk. It had not 

 eaten the leaf which conceale<l it, ))ut another at a little distance, so that it must 

 have come completely forth to feed. Two days later, on again" slitting the leaf, 

 I could see that the neck of the caterpillar was swollen, — sure sign of an ap- 

 proaching moult. The moult w\as discovered to have taken place after anothet 

 interval of two days, and the caterpillar was moving about. For the present it 

 rested on the midrib of a fresh leaf in full view, but on the third day it stitched 

 the edges together slightly, and retired. Just then I was compelled to leave 

 home, returning on 23d, and left my subject in chai'ge of a member of my family. 

 It w^as reported healthy, and the day I returned closed up the hitherto open end 

 of its leaf, and was seen no more, and evidently did not come out to feed till after 

 the 27th, on which day it passed the second moult. On 5th September, it had 

 covered itself within a leaf, both edges of which rested on the side of the glass, 

 and had fastened them to the o-lass, so that from the outside I had a good view. 

 On 9th, I saw it at a distance from its nest, and same day caught it retreating 

 into it. On 11th, it passed the third moult. Soon after, I sent this caterpillar to 

 Mrs. Peart, in Philadelphia, by express, in its glass jar, for a portrait. The dis- 

 tance is about six hundred miles, and the package was three days in reaching its 

 destination. On 21st, I received the caterpillar again, quite uninjured l)y the 

 journey, and by six days of close confinement. It was concealed when it reached 

 me, and two days later it passed the fourth and last moult. Three days later, it 

 again went to Philadelphia, for another portrait, and there remained till pupation. 

 This occurred 9th October, and the imago came from chrysalis 11th November, a 

 female, rather smaller than the average of the free females, but fully as large as 

 any male. So that it had not been much afiected by change of climate and food, 

 confinement and travel.
