ii. Reared the second generation from eggs of the first 

 generation. Emerged from the eggs on June 6th, 1872, 

 pupated on July Qth. The pupae were placed on ice 

 (o 1 R.) from July nth till September nth, and 

 then transferred to a hothouse, where all emerged : 



On the 1 9th of September, 3 male Prorsa, I male/V 



rima. 



2 1st 13 Porima (12 males, I 



female) 2 female Levana. 



22nd 14 Porima (12 males, 2 fe- 



males) and i female Le- 

 vana. 



23rd 10 female Levana, 3 male 



Porima. 



24th 5 female Levana. 



25th i female Levana. 



27th 3 female Levaua. 



4th of October, i male Porima. 



Total . . 57 butterflies (32 males and 

 25 females), only 3 of which were Prorsa, 32 Porima^ 

 and 22 Levana. 



It must be pointed out, however, that among those 

 specimens marked as " Levana " there were none which 

 entirely corresponded with the natural Levana y or which 

 indeed approximated so nearly to this form as did 

 some of the specimens in Exp. 9. All were larger 

 than the natural Levana, and possessed, notwithstanding 

 the large amount of yellow, more black than any true 

 Levana. In all artificially bred Levana the black band 

 of the basal half of the hind wings is always interrupted 

 with yellow, which is seldom the case with true Levana. 

 The whole appearance of the artificial Levana is also 

 coarser, and the contour of the wirigs somewhat different, 

 the fore-wings being broader and less pointed. (See figs. 

 7 to 9, PL I.)-
