New or lilile-knoum Xylophilidae. 35 



39. Xylophilus parvicollis, n. sp. 



cJ. Moderately elongate, depressed, shining; piceous. the bead 

 (the eyes excepted), prothorax, and an indeterminate, short, curved 

 streak on the elytra extending from the humeri to the post-basal 

 depression, ferruginous; antennae black, with joints 1-3 testa- 

 ceous and the tip ferruginous ; anterior and intermediate legs 

 (except the tibiae of the intermediate pair in part), and the outer 

 half of the posterior tarsi, testaceous, the rest of the posterior pair 

 .piceous; densely, finely, the elytra more coarsely, punctate; 

 closely, finely pubescent. Head convex, moderately broad, rounded 

 at the sides behind, the eyes rather small, convex, distant from the 

 base, feebly emarginate, and separated by nearly their own width ; 

 antennae moderately long, rather stout, joints 2 and 3 more slender, 



3 small, not longer than 2, 4-10 rapidly decreasing in length, 



4 longer than broad, 5-8 about as broad as long, 4-6 distinct!}' 

 wider than those following, 9 and 10 transverse, 11 acuminate- 

 ovate. Prothorax small, broader than long, quadrate, narrowed 

 in front, transversely grooved before the base. Elytra moderately 

 long, mucli wider than the head, subparallel, deeply, transversely 

 depressed below the base. Legs long, slender; posterior femora 

 moderately thickened, angularly dilated at a little beyond the 

 middle beneath.

II ab. Assam, Patkai Mts. (Doherty). 



One specimen, assumed to be a male. The rather long 

 head, small, quadrate prothorax, broad, subparallel. 

 depressed elytra, and peculiarly formed antennae give 

 this insect a distinctive facies. The three basal joints of 

 the latter are clear testaceous and rather slender, and the 

 three infuscate joints following are slightly stouter than 

 7-10. X. dohertyi, Pic, from Perak, seems to have similarly 

 formed antennae, but differs in colour, etc. Allied forma 

 are before me from Tenasserim and Siam. They have the 

 general appearance of Anthicids. 



40. Xylophilus siamensis, n. sp. 



<J. Elongate, depressed, shining; ferruginous, the elytra nigro- 

 piceous. with the basal third testaceous, the antennae black, red- 

 dish at the base and tip. tin- legs testaceous, the intermediate and 

 posterior tibiae infuscate in their outer half; closely, finely, the 

 elytra more coarsely, punctate; finely pubescent. Head transverse, 

 rounded at the sides behind the eyes, the latter lerately large,
