exposed best when the owner is in repose, would then be a serious ob- 

 jection to such considerations. Also it is very improbable that such 

 markings are so much conspicuous as to be useful in such a manner as 

 mentioned above, when the butterflies are on the wing. It seems to me 

 that the etiological significance of the eye-spots, if any, would bt- very 

 similar to that of the ordinary markings on the upper surface, that is, for 

 their own and not for enemies. This seems to be supported by the facts 

 that one often mtets with a Satyrid, reposing in the sun, and raising and 

 lowering its wings as if it displays on purpose the eye-spots on the upper 

 surface to other members of the species, and that the diminutive varia- 

 tion of the eye-spots in the dry forms seems to be sometimes compens- 

 ated v'ith some other markings on the upper surface.
