XIII. On the Lucanidse of Japan. By Geoege Lewis. 

 [Eead July 4th, 1883.] 



Plate XIV. 



There are fifteen species of Lucanini and one species 

 of Passalini known now from Japan, and the list of 

 these, with their synonymy, stands, I believe, as 

 follows : — 



Lucanini. 



Lucanus maculifemoratus, Motsch. Macrodorcus striatipennis, Motsch. 



= 8ericans, Voll. = binervis, Motsch. 



— Hopei, Parry. = cribeUatus, Motsch. 



Cladognathus inclinatus, Motsch. = opacus, C. Waterh. 



= mandibular is, Thorns. = Vanvolxemi, Lewis. 



= inflexus, Harold. Dorcus Hopei, Saund. 



Prismognathus angularis,G. Waterh. = binodulosus, C. Waterh. 



Eurytraclidus platymelus, Saund. digits siibnitidus, G. Waterh. 



= castanicolor (Serrognathus), Platycerw delicatulus, n.s. 



Motsch. Figulvs binodulosus, C. Waterh. 



Macrodorcus rubrofemoratus, Motsch. „ punctatus, C. Waterh. 



,, montivagus, n.s. Ceruchus Kgnarius, n.s. 



,, rectus, Motsch. Msalus Asiaticus, n. s. 

 = Niponemis, Voll. 



= diabolicus, Thorns. Passalini. 



= rugipennis, Motsch. Aulacocyclus patalis, n.s. 



There is no Sinodendron known yet from Japan. 



In this list I have omitted Lucanus Cantori, Hope, 

 and Prismognathus dauricus, Motsch., because the evi- 

 dence of their being natives of Japan seems to me 

 insufficient. Lucanus Cantori is a native of Assam, 

 and although Motschulsky says, in the ' Etudes ' of 

 1860, that Madame Goschkevitch obtained it in Japan, 

 in the ' Etudes ' of 1861, in treating of the same mate- 

 rial, he gives us, without any reference to Cantori, 

 maculifemoratus. His first determination thus appears 

 incorrect, and the specimens available to-day from 

 Japan confirm this. By the kindness of Major F. J. S. 

 Parry I have been able to examine specimens of 

 Prismognathus dauricus from the mainland of Asia. 

 Motschulsky described this in 1860, but his remarks in
