tubercles.^ The head is also narrower and rounder, with 

 its posterior angles more reflexed ; finally the sculpture is 

 more diffuse, and less pronounced. In their respective 

 females the same difference in the character of the sculp- 

 ture is observable ; moreover inZ. Sicinhoei ? the anterior 

 angles of the prothorax are more rounded. Two speci- 

 mens were received from Consul Swinhoe, to whom we 

 are already indebted for numerous interesting additions to 

 the Entomological Fauna of China.

I am indebted to Dr. Taschenberg for the opportunity 

 of identifying a species hitherto somewhat questionable to 

 many entomologists. In the 1st edition of my Catalogue 

 of the Lucanoid Coleoptera, Tr. Ent. Soc. 1863, D. eu- 

 rycephalus was referred, upon the authority of Professor 

 Lacordaire and Mons. Reiche, as a synonymy to E. Bu- 

 balus, Perty, while the latter insect was subsequently 

 found to be only a var. minor oi E. Bucephalus (\dd. Cat. 

 2nd edit. 1870, p. 89). It may now be affirmed without 

 doubt, upon examination of one of two specimens existing 

 in the Museum of Halle, from which Dr. Burmeister 

 made his description, that E. eurycephalus is a distinct 

 species, and moreover that upon comparison it is found to 

 be identical with E. Candezii, Parry, the latter exhibiting 

 a somewhat smaller development, with the internal sub- 

 apical tooth of the mandibles but very slightly produced, 

 causing these organs to appear acute, and not forked at 

 their apex, according to Dr. Burmeister's description. As 

 regards the tAvo perfectly uniform auricular impressions on 

 the prothorax of the E. Candezii, they must, I am satis- 

 fied, be considered as purely accidental and quite ab- 

 normal, no trace of them existing in the specimen received 

 from Halle.
