Deyrolle described a single male example from Celebes, but the real locality of this 
species is now known to be not Celebes (Menado) but the neighbouring island of 
Sangir. In addition to the fifteen specimens contained in the collections of Messrs. 
Parry and van Lansberge, I have examined series of this species in the museums of 
Leyden and Paris.

Male. Deep black, only the outer margin of the elytra reddish brown; mandibles, 
head, and prothorax dull, finely punctured. Head quadrangular, canthus narrow, 
behind the eyes is an obtuse horizontal spine; lower part of the cheeks pitted; sides 
of the prothorax with only one concavity, bispinose, the spines produced into a fine 
point; rim of the prothorax smooth beneath; prosternal process pointed, variable ; 
elytra shining, black, with a reddish-brown border both on the upper and under sur- 
faces; on the upper surface this border is generally no broader than beneath, but it 
happens sometimes, though very rarely, that it is broad enough to cover half the 
elytra; front tibize with from three to five teeth above the terminal fork. 
Mandibles. 
1. Forma telodonta——Mandibles as long as the head and thorax together, gently 
curved, flattened, the tip deeply forked, the front branch generally with three and the 
hinder with two teeth. About two thirds of the length from the tip stands a tooth 
slightly projecting forwards. Base of the mandibles unarmed. Head with the frontal 
margin strongly convex. Labrum depressed between the mandibles (fig. 1). 
2. Forma mesodonta.—Mandibles as long as or rather longer than the head, flattened, 
and rather compressed, with four or five unequal teeth at the tip. In the middle isa 
strong rounded tooth projecting downwards, and those on the opposite sides nearly
