“ Professor Westwood’s descriptions of the two last species were subsequent to 
those of Mr. J. Thomson.

(1843). Cantharolethrus Georgius, Thoms. Cat. p. 411 (1862). 
“In alluding to the priority of Mons. Buquet’s description of this interesting 
insect from Columbia (vide Tr. Ent. Soc. ser. 3, vol. i. p. 446), I referred to its con- 
nexion with the Chiasognathide rather than with the Lucanida, in which family Mr. 
Thomson has located it, placing the genus immediately before Lucanus. Upona 
further examination of the species in question, I am now disposed to modify my former 
opinion, although not to the extent of placing Cantharolethus next to Lucanus; I 
think it has greater affinity to Cyclommatus, Macrocrates and Leptinopterus; to Cy- 
clommatus in the triangular and depressed form of the head, the smooth and polished 
character of the elytra, and the unarmed four posterior tibiw ; to Macrocrates in the
