Lucanoid Coleoptera. 59 



author considers it should be located near G. Spencii, C. 

 hulbosus, and G. crenicollis ; he points out^ however, the 

 essential difference in the character of the mandibles. 



Gladognathus Lorquinii. 

 Deyr. Ann. Soc. Ent. Belg. 1865, p. 26, pi. i. fig. 2. 



This species from Celebes (Menado) is allied to G. late- 

 ralis, Hoj^e, but the author describes it as being abundantly- 

 distinct, not only in form, but also in the disposal of its 

 coloration. Both the r^ and ? are, I believe, in Count 

 Mniszech's collection. 



Gladognathus MotschulsMi. 

 C. 0. Waterh., Trans. Ent. Soc. 1869, p. 14. 



The error already mentioned under Gladognathus Batesi 

 arose also with regard to this new species from Japan. 



Gladognathus vittatus. 

 Deyr. Ann. Soc. Ent. Belg. 1865, p. 28, pi. i. fig. 4. 



Several specimens of this species from the Philippine 

 Islands were brought to this country by the late Mr. Hugh 

 Cuming; it has hitherto been considered a variety of G. 

 lateralis, Hope. Mr. Hope and Dr. Burmeister do not 

 appear to have noticed it in their respective publications, 

 although, probably well acquainted with it. The two 

 species are evidently closely allied. Mens. H. Deyrolle 

 however, in his description, points out various difierences. 



Gyclophthalmus Kaupi, G. & H. Cat. Col. iii. 953. 



Gyclommatus Kaupii, Deyr. Ann. Soc. Ent. Belg. 1865, 

 p. 30, pi. ii. fig. 2. 



This new species, dedicated by the author to Dr. Kaup 

 of Darmstadt, is from the island of Celebes. 



We have here an instance of the great inconvenience 

 arising from the unsettled state of the nomenclature of 

 genera. My attention has been called to this subject, 

 by the restitution of Mr. Hope's name Gyclophtlialnius ; 

 this appropriate designation was recorded both by Dr. 

 Burmeister and Professor Lacordairc in their respective
