F. A. Dixey as to whether it would be possible definitely to 

 recognise scales of Caiopsilia forella, but unfortunately the 

 scales of this butterfly are not very distinctive. The ex- 

 amination showed how rapidly all ordinarily visible traces 

 of lepidopterous remains are obliterated by the digestive 

 processes of the bird, and how useless would be the investiga- 

 tion of the contents of birds' stomachs except by careful 

 observation under the compound microscope. He had also 

 examined some faeces of a wagtail dated 16.12.19, but had 

 not found traces of Lepidoptera in same. 



The recent date of the invasion of Madagascar by 

 Hypolimnas bolina, L. — Prof, Poulton said that a few 

 weeks ago he had received the following message from M. 

 Charles Oberthiir, whose vast experience of Malagasy butter- 

 flies made the negative evidence unusually valuable. By 

 a curious coincidence M. Rene Oberthiir received an example 

 of the species on the very day when the question was asked 

 and answered. 



"May IG, 1920. Eennes. 



" My brother has received the Indian form of Hypolimnas 

 bolina, to day, from Vangaindrano, in the southern part of 

 Madagascar. I have not hitherto received the Indian form 

 from this island." 



It would be remembered that Archdeacon Kestell-Cornish, 

 now Bishop of Madagascar, considered that bolina first appeared 

 in 1912 or a little earlier (Proc. Ent. Soc, 1916, p. xxiii).
