of Lucanoid Coleoptera. 45 
tatis; tibiis anticis extus 4 vel 5-dentatis, quatuor posticis 
spina minuta instructis. 
Long corp. (mandib. incl.) lin, 94. 
Hab. Borneo et Java. 
Although no mention of the sex is made in the Rey. 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 Eurytrachelus, 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- 
nathus) gracilis, Saund., and piceipennis, Westw.
