their young ; and although the Heliconidfe swarmed in the 

 vicinity, and from their slow flight could have been easily 

 caught, not one was ever pursued, although other butterflies 

 did not escape. His tame monkey also, A\hich would greedily 

 munch up other butterflies, would never eat the Heliconidae. 

 It would sometimes smell them, but always rolled them up in 

 its hand and then dropped them. 



We have also some corresponding e^ddence as to the 

 distastefulness of the Eastern Danaida?. The Hon. Mr. 

 Justice Newton, who assiduously collected and took notes 

 upon the Lepidoptera of Bombay, informed Mr. Butler of the 

 British Museum that the large and s^Wft- flying butterfly 

 Charaxes psaphon, was continually persecuted by the bulbul, 

 BO that he rarely caught a specimen of this species which had 

 not a piece snipped out of the hind ^Yings. He oftered one to 

 a bulbul which he had in a cage, and it was greedily devoiu'ed, 

 whilst it was only by repeated persecution that he succeeded 

 in inducing the bird to touch a Danais.^ 



Besides these three families of butterflies, there are certain 

 groups of the great genus Papilio — the true swallow -tailed 

 butterflies — which have all the characteristics of uneatable 

 insects. They have a special coloration, usually red and 

 black (at least in the females), they fly slowly, they are very 

 abundant, and they possess a peciUiar odour somewhat like 

 that of the Heliconidae. One of these groups is common in 

 tropical America, another in tropical Asia, and it is curious 

 that, although not very closely allied, they have each the same 

 red and black colours, and are very distinct from all the other 

 butterflies of their respective countries. There is reason to 

 believe also that many of the brilliantly coloured and weak- 

 flying diui-nal moths, like the fine tropical Agaristidae and 

 bm^net- moths, are similarly protected, and that their con- 

 spicuous colours serve as a warning of inedibility. The 

 common burnet-moth ( Anthrocera filipendula) and the erjually 

 conspicuous ragwort-moth (EucheHa jacobeai) have been proved 

 to be distasteful to insect-eating creatures. 



1 Nature, vol. iii. p. 165, Professor Meldola observed that specimens of 

 Danais and Eupla?a in collections were less subject to the attacks of mites 

 (P/'oc. Eiit. Soc, 1877, p. xii.) ; and this was con-oborated by Mr. JeuuerWeir. 

 Entomologist, 1882, vol xv. p. 160.
