no doubt mainly an upland assemblage, falls somewhat apart in 

 aspect from the vieljwmene-like Heliconii, but it is to be observed 

 that the latter are not entirely confined to the lowlands. Two 

 species from Ecuador here shown (//. vidcamis and H. cyrhia) 

 are from series captured at an elevation of 3500 feet, which is 

 quite high enough for any Pereute. Still more important is 

 the fact that many other forms are seen to exist which may 

 very well bind together the inhabitants of the heights and 

 of the plains in one mimetic assemblage ; the Catagrammas, 

 for instance, are stated to occur at all elevations. Another 

 fact to be borne in mind is that the distribution and move- 

 ments of the enemies have to be taken into account as well 

 as those of their prey ; and until we know for certain that 

 these enemies are similarly limited in their range, we cannot 

 well exclude the possibility of the extension of the mimetic 

 influence of a given species beyond its own area of distribution 

 ** It may be remarked, in conclusion, that the ' aposeme ' 

 shades off in various dii-ections ; one of them being probably 

 exemplified by the Erycinids exhibited, and another by the 

 Actinotes."
