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 shawt, found at 
a similar elevation m Ladak. 
‘“Phulia, 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 butleri, 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. Verratt : Homeochromatism was not a phenomenon 
confined to the tropics. Homcochromatic 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. Swrrnor: A challenge had been held out as to whether 
the distasteful qualities of protected Lepidoptera had been 
experimented on. As an example of a species, of which such 
qualities were placed beyond doubt, he instanced Danais 
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 eyen 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. Jacosy: If protected and inedible species were so
