we obtained the abnormally formed butterflies from. We 

 obtained in this second generation 17 females, 10 of these had 

 most of the color characters of the yellow male ; however, the 

 appendix as the male had it which we used in crossing, was 

 found in only two of these females, and only small ; the other 

 seven had some of the characters of the purple female. We 

 obtained 15 males, 12 of these had the color characters of 

 the yellow male ; and three had the ocellus of the hindwing 

 almost purple in color and some purple on the forewing; of 

 these males only one had a small appendix. In this genera- 

 tion we obtained one female with the right antenna missing; 

 another had the left one missing; and one with the left an- 

 tenna the full length, but the right one of only a quarter 

 length, and a little club on it. 



When we obtained these abnormally formed specimens in 

 the first generation, we still considered it as an open question, 

 if not possibly by accident the missing antennae were broken 

 off; however, this was never before observed, and it seemed 

 almost impossible, as these thin organs are very elastic as 

 long as the butterfly is alive. Now, however, that we got 

 this phenomena repeated, in some of the descendants, it is 

 without doubt a natural phenomena which is inheritable. 

 Especially the last one with one antenna the full length, and 

 the other only one quarter length, and still a little club on it, 

 is of some significance. 



We tried the feeding experiment once more, the first 

 emerged female, with the right antenna missing, was put 

 alone in a cage and not fed during the first 24 hours ; the next 

 morning we placed a moist white sugar cloth near it, and it 

 started to suck immediately; it must have been very hungry 

 by this time, but, all the same, it did not fail to bend six 

 times, the one antenna to the sugar cloth ; then we pushed a 

 piece of white paper over the cloth, it rolled up the tongue. 

 and never bent the antenna on the paper or unrolled the 

 tongue; after the paper was removed, sideways, it sucked 

 again, without feeling, to appease its hunger. 



As it is well known that Junonia is one of the highly 

 developed butterflies which turns, generally, its tail in the 

 direction to the sun while at rest, for the only reason, we 

 believe, to see better. To find out if the antenna had any- 

 thing to do with this habit, we turned the sugar-cloth in a 

 circle, horizontallv from left to right; this butterfly turned 

 just as quick in the opposite direction to retain its customary 

 position without interruption from feeding; we repeated this 

 turning around, but changed the direction from right to left, 

 and this butterflv also changed the direction, however, not 

 always; and it seemed to become tired, or found it useless 

 to turn anv more; after eight times repeated turning it re-
