New or little-known XyhphMidae. 17 



L5. Xylophilus ephippiatus, n. sp. 



(J. Short, shining; testaceous, the head black, the elytra with a 

 transverse mark at the base near the seutelhnn and a common 

 interrupted median fascia (formed by a triangular patch at the 

 sides and a broader subtriangular patch across the suture) piceous, 

 the posterior femora and tibiae slightly infuscate; head and pro- 

 thorax closely, finely, the elytra a little more coarsely, punctate; 

 finely pubescent. Head short, broad, very narrowly extended on 

 each side behind the eyes, the latter large, deeply emarginate. and 

 narrowly separated; antennae rather slender, joint 2 short, half 

 the length of 3, 3 and 4 about equal, cylindrical [6-11 broken oft']. 

 Prothorax transversely Bubquadrate, obliquely narrowed in front, 

 narrower than the head, with a faint, shallow, arcuate depression 

 before the base. Elytra a little wider than the head, gradually 

 narrowing from near the base, with a shallow, oblique, post-basal 

 depression. Legs rather short; anterior tibiae slightly widened, 

 simply arcuate, the intermediate pair feebly curved ; posterior femora 

 stout, with a slender, sharp tooth near the tip, and furnished with 

 a narrow, setulose pad along their lower face.

Hob. Tenasserim, Tavoy (Doherti/). 



One male. Smaller and narrower than X. diversiceps, 

 Pic, from Ceylon (the female only of which is known) ; 

 the elytra less coarsely punctate, the dark basal markings 

 not extending down the suture, and the common median 

 fascia divided into two triangular patches on each elytron; 

 the posterior femora very much stouter. Unless these 

 insects were obtained at the same locality, it would be 

 unsafe to treat them as the sexual complements of one 

 species.

 (1896) (part.). 



cJ. Oblong, shining; rufo-testaceous, the eyes black, the posterior 

 femora slightly infuscate; the entire upper surface densely punctate, 

 the punctures on the elytra rather coarse; finely pubescent. Head 

 short, broad, the eyes small, not reaching the base, feebly emarginate ; 

 antennae subfiliform, moderately long, rather stout, joints 2 and 'A 

 about equal, 4 longer than 3, 4-10 very gradually decreasing in 

 length, 11 rather stout, acuminate-ovate. Prothorax not quite so 

 wide as the head, short, transversely quadrate, abruptly, obliquely
