Would like tabulation of horned beetles if not too troublesome, but would easily settle for general remarks.
On the subject of other species mocking Heliconidae, asks whether full-coloured ones were mocked. Expresses full belief in HWB's theory.
Encloses a copy of A. R. Wallace's letter to the Field requesting observations on which caterpillars birds devour.

Would not the tabulating the Horned Beetles be very troublesome: if not I certainly sh
Your remarks in answer to my lady-friend (Miss Tollet daughter of late
I suppose you have, of course, seen his letter to the Field; but I enclose a couple of copies.—
Many thanks about Junonia— whenever I go to B. Museum, I will ask to see the genus & will look at the differences & similarities in the sexes.—; it seems a capital case. You have indeed given me most valuable information:—
Dear Bates | Yours very sincerely | Ch. Darwin
I have just finished hearing read aloud your Amazon Book, & liked it better
I shall send your letter to Miss. T, as she begged me to do.
- f1 5476.f1The year is established by the relationship between this letter and the letter from H. W. Bates, 29 March 1867.
- f2 5476.f2See letter from H. W. Bates, 29 March 1867.
- f3 5476.f3See letter from H. W. Bates, 29 March 1867. Emma Darwin recorded in her diary (DAR 242) that Georgina Tollet visited Down House from 7 to 21 March 1867. Georgina's father, George Tollet, had resided at Betley Hall, Staffordshire (Freeman 1978). Georgina, a childhood friend of Emma, had read and commented on a manuscript of Origin (see Correspondence vol. 7).
- f4 5476.f4CD mentioned this idea in Descent 1: 412. Bates had speculated about the early stages of mimicry in the development of Leptalis butterfly species that came to resemble Heliconidae species (see letter from H. W. Bates, 29 March 1867 and n. 7).
- f5 5476.f5CD had praised Bates's paper on mimicry (Bates 1861), and had written a positive review of it (see Correspondence vol. 11, and `Review of Bates on mimetic butterflies'). CD added a discussion of Bates's discovery of mimicry in butterflies to the fourth edition of Origin (see Origin 4th ed., pp. 503--6).
- f6 5476.f6For the case of turkeys rejecting a moth, see the letter from A. R. Wallace, 24 February  and nn. 5 and 6. This case had been discussed at the 3 December 1866 meeting of the Entomological Society of London; in Descent 1: 411, CD cited the report of this meeting as confirming Bates's hypothesis that the Heliconidae were protected from attack by birds by a secretion or odour.
