Zoolog. Record 1867.

p.250 - Lucanus cervus ♀ as 6 : 1

["Cornelius remarks (Stett. ent. Zeit. 1867, pp. 435-437) upon the occurrence of unusual numbers of Lucanus cervus in the neighbourhood of Elberfeld, and thinks that, as in the case of the cockchafer, this excessive abundance may be a periodical phenomenon. He mentions the retention of life by the head and fore part of these insects when all the rest of the body has been torn away, and also the disproportion of the sexes, the ♀♀ being to the males as 6 to 1." Record of zoological literature 4.]

260 number of sexes - Elateridæ 2 or 3 male to 1 female

["Cardiophorus exaratus (Erichs.). Abeille de Perrin describes the habits of this species, as observed by him near Marseilles. The males are more numerous than the females, and during the day scarcely any of the latter are to be seen; in the evening the females come out, and copulation takes place, when two or three males are often found united with one female. (Ann. Soc. Ent. Fr. 4e s6r. vii. pp. 66-66.)." Ibid.]
