Dear Wallace

I much regretted that I was unable to call on you, but after Monday I was unable even to leave the house. On Monday evening I called on Bates & put a difficulty before him, which he could not answer, & as on some former similar occasion, his first suggestion was, "you had better ask [[2]] Wallace". My difficulty is, why are caterpillars sometimes so beautifully & artistically coloured? Seeing that many are coloured to escape danger I can hardly attribute their bright colour in other cases to mere physical conditions. Bates says the most gaudy caterpillar he ever saw in Amazonia (of a Sphinx) was conspicuous at the distance of yards [[3]] from its black & red colouring whilst feeding on large green leaves. If anyone objected to male butterflies having been made beautiful by sexual selection, & asked why sh[oul]d. they not have been made beautiful as well as their caterpillars; what would you answer? I could not answer, but sh[oul]d. maintain my ground. Will you think over this, & some time, either by letter or when we meet, [[4]] tell me what you think. Also, I want to know whether your female mimetic butterfly is more beautiful & brighter than the male?

When next in London I must get you to show me your Kingfishers.--

My health is a dreadful evil, I failed in half my engagements during this last visit to London.--

Believe me | yours very sincerely | C. Darwin [signature]
