Long. corp. (mandib. incl.) lin. 14|. 



Hah. — Java. 



This species was kindly added to my collection by Dr. 

 Candcze, the well-known entomologist of Liege ; a know- 

 ledge of the var. max. would be highly interesting, in 

 regard especially to the singular impressions on the pro- 

 thorax, no other instance of the same kind occurring in 

 any of the allied species of this genus. 



Eurytrachelus opacus. 

 Macrodorcas opacus, C. Waterh. Ent. Mo. Mag. vi. 208. 



A single specimen (var. min.) from Japan, is in the 

 British Museum. It appears to be closely allied to nipo- 

 nensis, Voll., now placed in the genus Eurytraclwlus. E. 

 niponensis may, I think, with great probability ]irove 

 hereafter to be identical with Macrodorcas rectus of Mots- 

 chulsky, but for the present it is, I think, advisable to 

 retain it in the position it has hitherto occupied; and I 

 am further of opinion that, should niponensis prove to be 

 identical with rectus, upon which the genus Macrodorcas 

 was founded^ it is not entitled to generic rank. 



Eurytrachelus fuivonotatus . 



Cladognatlms fulvonotatus, $ (var. max.), Parry, 



Cat. p. 81. 



Gladognathus bisignatus, (^ (var. min.) ? , Parry, I. c. 



Having now examined numerous specimens of C. his'ig- 

 oiatus, I am fully satisfied that it axid fulvonotatus ought 

 to be united, bisignatus $ representing the var. minor, 

 in which the fulvous marginal line of the elytra present 

 in E. fulvonotatus is reduced to a mere apical dash, and 

 the fulvous spots of the thorax are entirely obliterated.
