ON SOME NEW XYLOPHILI FROM BORNEO AND PENANG: 



by g. c. champion, f.z.s. 



(Plate XXa.) 



Mr. Gr. E. Bryant lias submitted to me for description the 

 interesting series of XylophiU captured during his recent expedition 

 to Borneo, etc. There are 17 species in all, one (or two) common to both 

 islands, two from Penang only, and the rest from W. Sarawak, 

 Borneo, mostly from Mt. Matang. Some of them are nearly allied to 

 forms inhabiting Ceylon and Tenasserim.* All appera* to be un- 

 described, X. egregms and X. melanosoma representing peculiar types. 

 Seven species have been previously recorded from the mainland of 

 Borneo by Pic, viz., pangaronus, suhhrunneus, hiimpressus, nigronnacu- 

 latus, trimactdafus, marta pur anus, and roberti var. borneensis, the in- 

 complete descriptions of which do not accord with any of Mr. Bryant's 

 captures. The types of the new forms here described will be presented 

 to the British Museum by the captor. 



•1. — Xylophilus ciliatus n. sp. (Plate XXa, figs. 1, la, (^ .) 



^. Elongate, narrow, robust, flattened above, shining (when denuded), 

 piceoxis, the prothorax fusco-ferruginous, the basal tliird of the elytra obscvire 

 testaceous, the palpi, joints 1, 2, and 11 of the antennae, and the legs (the 

 posterior femora, and the posterior tibiae in part, excepted) ferruginous ; 

 densely, finely, the elytra rather coarsely, punctate ; thickly clothed with fine, 

 greyish pubescence, the elytra with a slightly darker, broad, sub-median 

 fascia. Head short, broad, narrowly extended on each side behind the eyes, the 

 latter very large, feebly emarginate, separated by less than half their own 

 width ; antennae rather stout, long, joint 2 short, 3 much longer, 4-10 each a 

 little shorter than 3, sub-triangular, about as long as broad, 11 acuminate-ovate. 

 Prothorax broader than long, much narrower than the head, quadrate, abruptly, 

 obliquely, narrowed in front, the anterior angles rather prominent, the disc with 

 a deep transverse impression before the base. Elytra long, a little wider than 

 the head, flattened, sub-parallel, the post-basal depression deep, oblique. Legs 

 long, rather stout ; anterior tibiae armed with a sharp triangular tooth at the 

 middle within ; posterior femora (fig. la) stovit, curved, furnished with a rather 

 long, prominent, arcuate, densely ciliate pad towards the apex beneath ; posterior 

 tibiae feebly curved. Length 2i, breadth | mm. 



Hab. : Borneo, Mt. Matang, W. Sarawak, alt. 1,000 feet [type] 

 (G. E. Bryant, 28.i.l4) ; Penang (G. E. Bryant: 6.xi.l3). 



Two males, precisely similar. This species approaches X. plani- 

 pennis Motsch., nee Pic, from Ceylon. A somewhat similar armature 

 of the posterior femora of the male is to be found in various other 



*Tlie Ceylon Xyloiihilids have recently been revised by me in Ann. and Mag. Nat. Hist. (8), xvi, 

 pp. 21.5-22(3 (September, I'.ilo).
