Summary
Working on sexual differences in collection of horned beetles and will send CD results.

To H. W. Bates 30 March [1867]
Summary
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.
