Lissotes (n. g.) reticulatus, Westw. 1855, Ent. Trans, vol. 3, 



N. S. p. 218. 

 Dorcas squamidorsis, White, 1846, Voy. Erebus and Terror, 



Zool. p. 9, pi. 2, fig. 2. 

 A^gus cicatrosus, Burm., Handbuch, 1847. 

 Dorcus Zealand'icus, Fairmaire, 1849, Revue Zoologique, p. 414. 



31. Sclerostomus ruhripes, Guerin ; Thomson, Cat. p. 400. Chili. 



The nomenclature of this species ought to stand thus, the name 

 o? femoralis, Guerin, having the priority : 



Dorcus femora lis, Guerin, Revue Zool. 1839, p. 303. 



Darrvimi, Hope, 1841, Ent. Trans, vol. 3. 



rubripes, Hope, Cat. 1845. 



Sclerostomus ruhripes, Burm., Handbuch, 1847, p. 424, 



Dorcus femoralis, Gay, Hist. Chili, Zool. 1851. 



Sclerostomus femoralis, Westw., Ent. Trans., N. S. vol. 3, p. 209, 

 pi. 12, fig. 9 a, 9 b. 



Dorcus rufifemoralis, Curtis, Gapt. King, Voy. Magellan ; Trans. 

 Linn. Soc. vol. 19, p. 456. 



Mr. Thomson appears to have fallen into the same error with 

 reference to the synonymy of this species as Dr. Burmeister has 

 done. M. Guerin described the species under the name o^ fe- 

 moralis, and not rubripes. 



32. Sclerostomus Lessonii, Buquet ; Thomson, Cat. p. 400. 

 Syn. rubrovittatus , Blanchard, Voy. D'Orbigny, pi. 12, fig. 9. 

 The synonymy to be rectified; D. rubrovittatus is quite distinct: 



both species are in my own collection. 



33. Sclerostomus leiocephalus, Solier ; Thomson, Cat. p. 400. 

 Assuming that the insect given by Mr. Thomson under this 



name is the species so designated by Solier, and described in Gay, 

 Hist. Chili, p. 53, of which the type, labelled in Solier's own hand- 

 writing, is in my own cabinet, 1 am of opinion that it is nothing 

 more than a small J of 5. rubripes, Guerin, in which the sides of 

 the prothorax are not uniform ; and am inclined to think that the 

 species in question has been founded on peculiarities arising from 

 mere malformation. I may also state, that Solier's fig. 5, pi. 15, 

 called D. leiocephalus, is in fact not this species, but D. mandi- 

 bularis $ , Solier, op. cit. p. 5Q. 



34. Ceratognathus {Nigidius, M'Leay) cormitus, Thomson, Cat. 



p. 403. 

 Syn. niger, Westwood. 

 Mr. Thomson has evidently confused Nigidius cornutus of 

 H H 2
