 ON SUMATRAN LUCANIDAE 



BY 



C. RITSEMA Cz. 



In a lot of Lucanoid beetles, captured in Deli (East- 

 Sumatra) and sent to rae for identification by Mr. J. D. 

 Pasteur of Batavia (Java), I found the following species 

 which were not yet recorded from Sumatra. 



Hexarthrius mandibularis H, Deyr. 



Prosopocoelus squamilateris Parry. 



Odontolabis Brookeanus Veil. 



Eurytrachelus rama Boileau. 



Aegus amictus H. Deyr. 

 » Eschsclwltzi Hope. 

 » higihhosus Rits. ^). 



Nigidius obesus Parry. 



Figulus rugosus H. Deyr. 



With the exception of Euri/trachelus rama Boileau (\e 

 Naturaliste, 1897, p. 191, fig.) and of Aegus bigibbosus 

 Rits. (ante p. 185) all these species are already known as 

 belonging to the fauna of Borneo. 



Leyden Museum, November 1897. 



1) I am happy to say that Mr. Pasteur most generously has offered the 

 type-specimen of this species to the coUecticms of the Leyden Museum.
