When twelve years later, during a temporary return to Europe, I gave a lecture 

 at a meeting of the Nederl. Entom. Vereeniging on some of my experiences 

 in connection with Malayan insects, a translation of which appeared in the 

 Entomologist for November 1877, I was afraid to communicate this fact. It 

 appeared to me so incredible that I feared I should not believed and that. In 

 consequence, the reliability of my other communications might be doubted. It 

 was not until later, when I came across similar instances of the tenacity of life 

 in EuPLOEAs in Moore's Lepidopicra of Ceylon, communicated by Dr. Thwaites, 

 that I ventured to publish my own experiences in this connection. It has also 

 happened to me subsequently that I received from the mountains a tin of 

 butterflies in papers which had been lying between large quantities of naphtaline 

 powder, certainly not less than five days ; while examining them a Euploea 

 suddenly, on the paper being opened, flew out and escaped at once through 

 the window. This insect certainly had also had its thorax squeezed several 

 days previously and yet it well managed to survive its imprisonment in the 

 paper in the naphtaline-saturated atmosphere. 



On page 5 of the Trans. Entom. Soc. London igo^ Mr. John C. W. Kershaw 

 states that while in China he observed a specimen of Epeh<a maculata which 

 had captured a Euploea Amymone Gdt. and had attackned the under side of 

 the abdomen and a part of the thorax, but upon releasing the butterfly from 

 its toils and placing it upon his hand it suddenly flew off and settled on a 

 high tree. 



Trimen observed analogous cases with reference to specimens of Danais 

 and Acraea which upon being released from the pin, on which his native hunters 

 had stuck them, flew away as if nothing unusual had occurred. 



In the case of two species I have repeatedly observed a yellowish-white &g^ 

 deposited on the under surface of a leaf. I noticed the 9 placing herself near 

 the margin on the upper side of the leaf and thereupon curve the abdomen 

 round the edge and press it against the underside. 



The larvae are provided with several pairs of appendages, whose number, 

 dimensions, and mode of attachment, vary in the different species. In the majority 

 of species, whose larvae are known, these processes in the full-grown larva are 

 long and four in number but in that of E. Mazares Moore they are short, 

 straight, and only three in number, thus agreeing with the processes in the 

 genus Danais. This rather points to the larvae of Euploea originating from 

 those of the genus Danais, especially since the young lar\-ae of the former 

 genus all have these processes short and straight and those of E. Mazares 

 Moore have, therefore, not kept pace in this evolutional change in that respect, 

 although the imago has assumed the new form, a fact which, moreover, occurs
