 very active habits, running briskly when disturbed. 



Hand-picking is the best remedy for these also : go carefully over 

 the infested branches and give no quarter. 



REARING BUTTERFLIES FROM THE EGG. 



By W. H. Edwards, Ccalburuh, West Va. 



I give herewith the conclusion to my experiments with Ajax and its 

 varieties. The Telamonidcs larva spoken of in my communication of 

 27th Feb. (vol. ii., p. 163) as having lived over the winter, on the 1st of 

 April, 187 1, produced male Telamonidcs (all the rest had yielded Marcellus 

 in 1870). The Marcellus larva: were mostly lost at the burning of my 

 house in February, but one was saved and yielded Telamonides female 

 on the 10th of April, 1871. 



We have a third well-marked variety very nearly the same as that 

 figured by Abbot, and for convenience 1 designate this as " Ajax var. 

 W'alshii." It is the earliest of the species in the spring. On the 10th of 

 April last 1 confined three females of this variety, and from them obtained 

 125 eggs, which in due time gave mc 70 chrysalids. From these emerged, 

 between the 1st and 6th of June, 22 male and 34 female Marcellus, 1 

 male W'alshii and 1 male Telamonides. On the 23rd of June, another 

 female Marcellus emerged, and still another on the T2th of July. The rest 

 of the chrysalids are alive at this date. 



On the 4th day of June last, I took two female Interrogationis fluttering 

 about my hop vine, and enclosed them in a keg which was covered with a 

 cloth and placed over a portion of the vine. They immediately began to 

 lay eggs, and from them I obtained 38 larvae, which, as they hatched, 

 I transferred to a breeding case in the house. From these larvae I had 

 18 chrysalids. between the 3rd and 9th of July emerged therefrom 5 males 

 and 6 females of Interrogationis (black-winged), 1 male and 5 females 

 Fabricii (red-winged), and one died. The larvae exhibited every distinct 

 type of coloration that I have hitherto noticed in these forms, and either 

 type of larvae produced either sex or form of butterfly indifferently. 



In part ix. of the ' ; Butterflies of N. A." (to appear in October), 3 plates 

 will be appropriated to the three varieties of Ajax, and 2 to Interrogationis 

 and its variety Fabricii, with detailed statements of my experiments and 

 observations. — July 13, 187 1.
