like Coontie, and lilies of all kinds. Mamma lost all her longifolium 

 lilies in one night, and they ate her Sago Palm clear down into the 

 ground, fairly hollowt-d out the bulb." I was told that the eggs were 

 generally laid upon Coontie, {Zamia integrifolia, one of the Cycadacece), 

 often called Sago Palm ; but I never once found them upon this plant. 

 Nearly all I saw, and they were very many, were on the Dwarf pahiietto. 

 They were laid in patches of from one hundred and fifty to two hundred 

 eggs, arranged in regular and symmetrical rows, very close together. 

 They were nearly globuhir in form, though flattened at base, cream 

 white or palest yellow in color, parsing day by day into amber, orange 

 and red, and becoming at last dark lead color, almost black before hatch- 

 ing. This took place on the tenth day. The young larvae fed freely on 

 lettuce, eating enormously. Once, having exhausted their food supply 

 they devoured a large piece of the muslin which covered their jar, and 

 this not to make an aperture through which they miglit escape, but for 

 food, as not one ran away. On another occasion when the larder was 

 low, some of them made a raid upon some specimens on my drying 

 boards, and ate the wings of several small moths. When shaken from 

 their perch they always spun a thread by which to hang. Being quite 

 inexperienced in the examination and description of larvae I made but 

 few notes, and these are quite incomplete. I was also travelling from 

 place to place durnig the growth of the caterpillars, and lost many of 

 them in transportation. 



But I sent some eggs, on the dav they were laid, to Prof Packard. 

 These reached him safely on the eve of his departure for Europe, and 

 he placed them in the hands of Mr. Joseph Bridgham for delineation. 

 Mr. Bridgham writes me that he has drawn them, much enlarged, in all 

 stages, so that their history will be beautifully preserved. I also gave 

 two full-grown larvae, of the five 1 brought home, to Mr. Henry Edwards, 

 who described them fully and technically, as I was unable to do. The 

 larvae, when first hatched, were very pale yellow, head shining black, 

 dorsal shield very prominent, black and shming, each segment bore a 

 transverse row of tubercles from each of which sprang a single long hair, 

 those on the back being black, those on sides white. Mr. Bridgham 

 writes : "The tubercles did not change in position during any moulting, 

 but changed much in regard to size. The long hairs, at first single and 

 double from the various tubercles, soon gave place to shorter and more 

 numerous ones. The dorsal shield on first segment diminished in size 

 at each change and the color of head and face also changed. I have 

 mounted a few c)f the hairs for examination under the microscope, as 

 they seem barbed peculiarly. 



The following is Mr. Edwards" description of adult larva.
