One male, as shown by the slender pi-otruding apical portion of 

 the aedeagus. An oblong, rather broad, flattened, ferruginous insect, 

 with the apical half of the elytra in great part infuscate, the latter 

 sub-parallel, rather short, and blunt at the tip ; the dense greyish 

 vestiture modifying the ground-colour, and replaced at the middle of 

 the elytra by a well-defined brown fascia. 



9. — Xylophilus inaequipes n. sp. (Plate XXa, figs. 2, 2a, ^ .) 



S . Sliort, shinmo- (when denuded) ; ferruginous, the elytra (the humeri 

 excepted) slightly infuscate, the eyes black ; densely, finely punctate, thickly 

 clothed with fine greyish pubescence. Head short, very bi'oad ; eyes large, 

 distant, feebly emarginate, occupying nearly the whole of the sides of the head, 

 the extremely narrow post-ocular portion of the latter appearing dentate 

 externally as seen from above ; antennae comparatively short, slender, joints 1 

 and 2 stouter, 3 a little longer than 2, 4 and 5 longer than 3, equal, 6-10 shorter 

 and wider, sub-triangular, 11 stout, ovate. Prothorax short, broad, nearly as 

 wide as the head, quadrate, abruptly narrowed in front, with a deep traasvei'se 

 basal sulcus. Elytra a little wider than the head, short, sub-parallel at the 

 base, the post-basal depression deep, transverse. Legs rather short, the inter- 

 mediate pair elongated ; anterior tibiae feebly curved, somewhat widened, finely 

 muci'onate at the tip within; intermediate femora (fig. 2a) abruptly dilated into 

 a large sub-triangvilar tooth before the apex, the outer face of the tooth ex- 

 cavate and pilose; intermediate tibiae (fig. 2a) long, strongly bowed, angularly 

 dilated at the middle within ; posterior femora slightly thickened, sub-angular in 

 front; posterior tibiae feebly curved and sub-sinuate. Length 1^, breadth f mm. 



Hab. : Borneo, Mt. Matang, W. Sarawak (G. E. Bryant : 30.i.l4). 



One male. The structure of the ^J -intermediate femora in this 

 minute insect is unique, so far as I am aware, amongst the known 

 Xylophilids ; the intermediate legs, too, are much elongated, and the 

 transverse basal sulcus of the prothorax unusually deep. The follow- 

 ing is an allied species. 



10. — Xylophilus setiger n. sp. 



cJ . Short, dull (till denuded) ; ferruginous, the eyes black, the antennae, 

 palpi, and tarsi testaceous ; densely, finely, the elytra a little more coarsely, 

 punctate, finely pubescent. Head short, broad ; eyes large, distant, entire, 

 occupying the whole of the sides of the head ; antennae short, slender, joints 1 

 and 2 stouter, 3 a little longer than 2, 3-5 sub-equal, 6-10 gradually becoming a 

 little shorter and wider, 11 ovate, rather stout. Prothorax transverse, narrower 

 than the head, somewhat rounded at the sides, with a shallow transverse basal 

 depression. Elytra short, a little wider than the head, sub-parallel at the base, 

 transversely depressed before the middle. Legs rather short, the intermediate 

 pair longer ; anterior tibiae mucronate at the tip ; intermediate femora angularly 

 dilated before the apex, the obliquely truncate, grooved outer portion furnished
