talis ; tibiis anticis extus 4 vel 5-dentatis, quatuor posticis 

 spina minuta instructis. 



Long Corp. (manclib. incl.) lin. 9^. 



Hab. Borneo et Java. 



Although no mention of the sex is made in the Rev. Mr. Hope's 

 description of this species, it proves upon examination of the type- 

 specimen to represent the female. Whether the given habitat of 

 Java is correct admits perhaps of some doubt, as specimens of 

 both sexes have lately been received from Borneo, and no other 

 specimen from Java has ever fallen under my notice ; it may, 

 however, notwithstanding be indigenous to both islands. The 

 male is now for the first time described and figured. 



In general form and structure of its mandibles, this species 

 assimilates somewhat to Eurytraclielus, differing however in its 

 narrow subparallel form, and in having the lateral margins non- 

 sinuate; in this respect being more in accordance with Hemiso- 

 dorcus, Thoms., in which for the present it is located, with (^Cladog- 

 nalhus) gracilis, Saund., and piceipennis, Westw.
