The following notes were sent by Dr. Carpenter, dated June 

 28, 1915 :— 



" The female parent laid 9 ova on or about April 26. All 

 save one hatched — 6 on May 3, 2 on May 4. 



'■ First ecdysis. Six May 8, two May 9.

The five males and two females, together with the female 

 parent, were exhibited to the meeting. The playtemoides was 

 as typical as any specimen could be of this variable form ; the 

 trophonissa was the typical western mimic of Danaida chry- 

 sippus, L. It was probable that the female parent was a 

 heterozygote between these two forms, which, by mating with 

 a recessive or a heterozygote male, had yielded the two original 

 parent forms, one of which had of course been latent in the 

 male. We were thus led- to conclude that heterozygotes of the 

 dardanus forms may exhibit intermediate or combined patterns, 

 although as a rule they bear the pattern of the dominant. The 

 proportions of the mimetic female forms, as shown by Dr. 

 Carpenter's collection to exist in the Kakindu forest, would be 

 brought forward with the specimens at a later date. In the 

 meantime it might be said that plamemoides, niohe and tropho- 

 nissa were all present, the first-named apparently in a high 

 ratio. In view of the probability that males bearing the 

 tendency of planemoides would often pair with females of the 

 two latter forms or vice versa, it was extremely unlikely that 

 the very rare female form captured by Dr. Carpenter bore 

 the usual appearance of the heterozygote resulting from such 

 matings.
