The clythra has not been noticed before I believe
Elater purpureus 187. 350. (nec loci) = Corymbites haematodes Fab. 1776. Cand.

The date is established by the relationship between this letter and the letter from Francis Darwin to Emma Darwin, [after 16 October 1868]. Francis wrote that Crotch would send specimens mounted on card. This list was probably sent with the specimens; the numbers evidently describe matching numbered specimens, none of which has been found in the Darwin Archive--CUL. In Descent 1: 379 n. 70, CD thanked Crotch for sending prepared specimens of various beetles. - +
- f2 6530.f2
Cychrus rostratus is now C. caraboides. - +
- f3 6530.f3
Clythra 4-punctata: i.e. Clytra quadripunctata. In Descent 1: 379, CD mentioned the location of stridulating organs in this species. - +
- f4 6530.f4
Crioceris brunnea: i.e. Lilioceris merdigera. - +
- f5 6530.f5
Crioceris 12-punctata: i.e. C. duodecimpunctata (the spotted asparagus beetle). - +
- f6 6530.f6
Crioceris cyanella is now Oulema gallaeciana. - +
- f7 6530.f7
Crioceris melanopa is now Oulema melanopus (the cereal leaf beetle). - +
- f8 6530.f8
Pelobius hermanni is now Hygrobia hermanni. - +
- f9 6530.f9
Crotch probably refers to Ceutorhynchus echii, now Mogulones geographicus. For more on stridulation in this species and other weevils, see Lyal and King 1996. - +
- f10 6530.f10
In Descent 1: 378--9, CD discussed the location of the stridulating organs in Necrophorus. - +
- f11 6530.f11
Strangalia elongata is now S. maculata. - +
- f12 6530.f12
Mesosa nubila is now M. nebulosa. - +
- f13 6530.f13
Agapanthia lineatocollis is now A. villosoviridescens. - +
- f14 6530.f14
Pachyta collaris is now Dinoptera collaris. - +
- f15 6530.f15
In Descent 1: 379, n. 70, CD noted Crotch's remark that the power of stridulation had not been previously observed in Clythra. On the synonymy of Elater purpureus with Corymbites haematodes, see Candeze 1863, pp. 95--6. This species is now Anostirus purpureus. Nec loci: neither place.
