to the same genus, and appears to agree with the 

 description of Lucanus virescens Fab., a species 

 omitted in the later works of Fabricius, being first 

 described in the Appendix to the Systema Entomo- 

 logies, p. 8 17. From a manuscript reference made 

 by Dr. Latham to Francillon's drawings, I was led 

 to infer this, as he states the size of the insect as 

 nearly three-quarters of an inch. 



Sp. 25. Punctatus. — Now a Figulus MacLeay. 

 The Baron De Jean includes under this term Lu- 

 canus cylindricus of De Haan, which insect is the 

 type of Mr. Westwood's genus Cardanus. 



13. iEsALUS. 



Sp. 1. Scarabceoides. — The only species known 

 of the genus. The remarkable insect named Co- 

 docera by Eschscholtz (which is the same as Stom- 

 phax of Fischer) seems to connect iEsalus with 

 Ceruchus and Sinodendron. For a better acquaint- 

 ance with the genera of Lucanidse, the student is 

 referred to Mr. Westwood's Synoptical Tables of 

 the Lucanidse, published in the Annales des Sciences 

 Nat. 2 series, Zool. tome 1, pi. 7, as well as Mr. 

 MacLeay's observations on this magnificent family 

 in the HoraB Entomological.
