﻿of Lucanoid Coleoptera. 57 



6 aut 7 aimatis, intermediis 4 — 5, posticisque 2 spinis mini- 

 mis instructis. 



Long. Corp. lin. 13 ; mandib. lin. 4. 



Hab. Ins. Gilolo. Coll. Wallace, Saunders, Parry. 



Mandibles falcate, broad at the base, within which is a large 

 tridentate process, and thence gradually narrowed to the tip. 

 Head broad, slightly depressed, deeply emarginate in front; the 

 angles of the emargination acute and obliquely prominent, and, 

 like the mandibles, delicately shagreened, with indistinct scattered 

 punctures, which are somewhat coarser on the sides and behind 

 the eyes. Prothorax smooth anteriorly ; the sides and hinder 

 margin with coarse punctures ; lateral margins straight ; posterior 

 angles much rounded. Scutellum shining, with a few deep punc- 

 tures. Elytra with the shoulders acutely angular ; base and 

 lateral margins with deep punctures ; dorsal surface depressed, 

 each with eight deep, longitudinal, punctate striae ; the interstices 

 sparsely and obsoletely punctate. Head, prothorax and abdomen 

 coarsely punctured beneath. 



This species, like all others of this genus, varies considerably 

 in size, and the remarkable tridentate process at the base of the 

 mandibles is entirely wanting in those of a minor development.

 stitiis planis, lateribus punctulatis ad apicem attenuatis; tibiis 

 anticis 4 vel 5 spinis armatis, intermediis unidentatis, posticis 

 inermibus; corpore subtus punctulatis j pedibus tarsisque 

 infra plus minusve ciliatis.

There is but little doubt, from the shortness of the mandibles 

 in comparison with the size and general appearance of the insect, 

 that the former have not in the present instance attained their full 

 development, and that in other specimens they will probably be 

 found to be of a different character. In the female the mandibles 

 are armed in the middle with a triangular tooth ; the head and 

 prothorax deeply and coarsely punctured, the anterior tibiae being 

 strongly dilated towards the apex.
