Chili and Patagonia, of several genera and species elsewhere 

 unknown in the Neotropical region, and which are isolated 

 from their congeners in North America by an enormous area 

 of country. 



" Among these Trifurcula huanaco is a remarkable species 

 which occurs in the Andes of Bolivia, at 16,000 to 17,000 

 feet, and has a marvellous likeness to Baltia shawi, found at 

 a similar elevation in Ladak. 



*^ Pliulia, a genus of three or four nearly allied species 

 also occurring at great elevations in the Andes and Chili, has 

 a striking resemblance to Synchloe hutleri, a species which 

 accompanies Baltia in Ladak. If similar conditions of en- 

 vironment do not produce similar effects, how can these 

 extraordinary cases of resemblance in remote and discon- 

 nected areas be accounted for ? " 



He hoped that entomologists who resided in places where 

 any of the supposed instances of protective mimicry occurred 

 would pay special attention to the life-history of the species 

 affected by it, as such observation alone could prove or dis- 

 prove the question. 



Mr. VfiRKiUiL : Homoeochromatism was not a phenomenon 

 confined to the tropics. Homoeochromatic resemblances 

 existed even in Europe between Diptera and Hymenoptera, 

 and it must be assumed that they stood in relation to the 

 protective armature of the Hymenoptera. 



Col. SwiNHOE : A challenge had been held out as to whether 

 the distasteful qualities of protected Lepidoptera had been 

 experimented on. As an example of a specias, of which such 

 qualities were placed beyond doubt, he instanced Banais 

 chrysippus, one of the most widely-spread protected models. 

 This insect was so free from attack, owing to its nauseous 

 character, that the protection extended even to dried 

 examples. These would be found untouched in a box of 

 insects, although the remainder of its contents had been 

 destroyed by mites or Anthreni. He did not doubt that 

 there were many other protected Lepidoptera, including many 

 Pierine genera — for example, all the species of Teracolus 

 appeared to be inedible, 



Mr. Jacoby : If protected and inedible species were so
