Mimetic Relationships iii ike genus Heliconius. 141 



to possess a certain degree of distastefulness. Another 

 species of Heliconius may resemble a Melinaea or a Lycorea. 

 We know that in most cases the Melinaeas are much 

 more numerous than Heliconius, and we may suppose 

 that the former are so much more unpalatable than the 

 latter that, in spite of the degree of distastefulness in 

 Heliconius, the latter may be practically a Batesian mimic 

 of the Melinaea. At the same time it is, perhaps, inappro- 

 priate to use the term Batesian in this connection, since 

 it was the mimicry of Heliconius which Bates himself felt 

 unable to explain on his own theory. To understand more 

 fully the relationships of models to mimics in Heliconius 

 we require much more information concerning geographical 

 distribution, and also as to comparative rarity of forms 

 and other bionomic factors. S. America is a very large 

 area, and the commonest type of data on our labels is 

 " Upper Amazon," " Colombia," " Peru," and even some- 

 times " Brazil." We might as well be told that a certain 

 insect occurs in Europe. 



Including the examples figured on PL XII the follow- 

 ing is a list of some of the most remarkable instances of 

 intrageneric mimicry in the genus.
