To B. D. Walsh   21 September 1868

Summary

Thanks BDW for pamphlets [by S. H. Scudder and J. D. Caton].

His information about Cicada is of extraordinary interest. Discusses stridulation organs which certainly sometimes differ in the sexes. CD would be curious to know if "dumb" Cicada can breed.

To B. D. Walsh   31 October 1868

Summary

Thanks BDW for extracts about "drumming" [of male Cicada to attract females].

Asa Gray and Hooker doubt that 13–year and 17–year Cicada forms should be considered distinct species. CD is inclined to agree with them.

Suggests observations be made of ratio of females to males in the rarer form.

BDW’s letter [6051?] and his notes are a "mine of wealth". The negative evidence is of much value. Sexual selection is a perplexing subject – finds he "must make the best of a rather bad job".
