still more nearly allied foi-m, with shorter le^^s, more sparsely punctate 

 elytra, a relatively shorter second autennal joint, and the anterior tibiae 

 of (^ widened, unbent, and armed with a long inwardly-directed spur 

 at the apex beneath. 



5. — Xylopliilus matangensis n. sp. 



(J . Oblong, narrow, somewhat depressed, shining ; obsciire testaceous, the 

 eyes black ; head rather sparsely, the prothorax densely, rugosely, and the elytra 

 coarsely and somewhat diffusely, punctate ; clothed with rather long pallid hairs. 

 Head short, broad, very narrowly, sub-angularly extended on each side behind 

 the eyes, the latter large, deeply emarginate, and separated by about half their 

 own width ; antennae long, not very slender, joint 3 slightly longer than 2, 

 3-10 veiy gradually becoming a little wider and shorter, 10 transverse, 11 stout, 

 obliquely acuminate. Prothorax much narrower than the head, transverse, 

 narrowed in front, parallel-sided behind, with definite basal depression. Elytra 

 short, not much wider than the head, narrowing from a little below the base, 

 with a deep, oblique, post-basal depression. Legs rather long ; anterior tibiae 

 feebly bent inwards at the apex, and mucronate at the inner apical angle ; 

 posterior femora stout, clavate ; posterior tibiae somewhat dilated and com- 

 pressed. Length (with head extended) If, breadth | mm.

One male. A small, unicolorous form, not unlike X. lenttis, but 

 with more slender limbs, a smaller, rugose prothorax, and coarsely 

 punctate, deeply excavate elytra ; the structure of the anterior and 

 posterior legs is very similar in the males of these tw-o insects. 



6. — Xylophilus acuminatus n. sp. 



<J . Moderately elongate, acuminate, robust, shining ; rufo-testaceous, the 

 elytra becoming slightly darker beyond the middle, the eyes and the apices of 

 the posterior femora black, the posterior tibiae rufo-piceous ; closely, finely, the 

 basal portion of the elytra a little more coarsely, pimctate; clothed with rather 

 long pallid pubescence. Head convex, short, moderately broad, narrowly 

 extended on each side behind the eyes, the latter large, deeply emarginate, and 

 separated by about half their own width ; antennae rather short, moderately 

 stout, joint 2 short, 3 twice as long as 2, 3-10 very gradually decreasing in 

 length, 11 acuminate-ovate, about as long as 9 and 10 united. Prothorax a little 

 broader than long, narrower than the head, convex, sub-quadrate, unimpressed. 

 Elytra not much wider than the head, rather long, somewhat rapidly narrowing 

 from the base, with a deep, oblique, post-basal depression. Iiegs long", ;5tout ; 

 anterior tibiae slightly sinuate within, feebly miicronate at the inner apical 

 angle ; posterior femora strongly clavate ; posterior tibiae somewhat dilated, 

 compressed ; posterior tarsi with a very elongate basal joint. Length 2\, 

 breadth a mm.
