New or little-known Xylophilidae. 13 



8-10 transverse, 11 stout, longer than 9 and 10 united, obliquely 

 acuminate. Prothorax convex, narrow, nearly as long as broad, 

 slightly rounded at the sides, unimpressed. Elytra a little wider 

 than the head, rather short, gradually narrowing from just below 

 the base, the oblique intra-huineral depression well-defined. Legs 

 moderately long; anterior tibiae bowed inwards from about the 

 middle, subangulate externally; posterior femora a little stouter 

 than the others; posterior tibiae somewhat dilated, feebly rounded 

 externally; basal joint of posterior tarsi feebly arcuate. 

 Length (with bead extended) 2, breadth 5 mm. 



Rah. Assam. Patkai Mts. (Doherty). 



One male. Near X. clavipes, from Tenasserim, but with 

 the legs and antennae much shorter and darker, the 

 posterior femora not nearly so stout, the body piceous, 

 the anterior tibiae bent in the $, etc. The dark body, 

 short antennae, narrower and more finely punctured 

 elytra, and less abruptly bent, non-mucronate anterior 

 tibiae of the <$, separate X. patkainus from X. cribricolUs 

 (= mucronatus), Pic, from Ceylon. X. melanotus, from 

 the same locality, the $ only of which is known, is a much 

 larger, broader, and more robust insect, with longer limbs, 

 a shorter apical joint to the antennae, etc., and it cannot 

 be the sexual complement of the present species. X. 

 patkainus is also very like the Brazilian insect here identi- 

 fied as X. obscuricolor, Pic, which has differently formed 

 antennae and stouter posterior femora. 



10. Xylophilus meranganus, n. sp. 



Oblong, robust, convex, shining; ferruginous, the head black, 

 the palpi, antennae, elytra, and let's (the partially infuscate inter- 

 mediate and posterior femora and tibiae excepted) testaceous; 

 densely, the elytra rather coarsely, punctate; clothed with rather 

 long, pallid hairs. Head short, broad, narrowly, subangularly 

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

 emarginate, and separated by about half their own width ; antennae 

 short, stout, joint 2 short, 3 longer, 3-10 gradually decreasing in 

 length, 3-6 about as long as broad, 7-10 transverse, 11 acuminate- 

 ovate. Prothorax large, a little narrower than the head, trans- 

 versely subquadrate, narrowed in front, unimpressed. Elytra 

 rather short, convex, wider than the bead, somewhat rounded at 

 the sides, narrowing from the basal third, without definite im- 

 pression on the disc. Legs comparatively short and stout ; postei ior
