New or little-known Xylophilidae. 7 



without definite impression. Elytra comparatively short, much 

 broader than the head, narrowing from a little below the base, the 

 usual depression on t he dise almost obsolete. Legs long; anterior 

 tibiae almost straight on their outer edge, hollowed towards the apex 

 (and thus appearing sinuous) within; intermediate femora curved; 

 intermediate tibiae broadly, triangularly dilated externally; posterior 

 femora curved, strongly incrassate, furnished with a broad, pallid, 

 setose pad along their lower face, and with a long slender tooth at 

 the inner apical angle; posterior tibiae strongly dilated, sinuous; 

 basal joint of posterior tarsi feebly curved.

Hub. Tenasskri.m, Tavoy [typej ; Siam. Renong. 

 Three specimens, captured by Doherty. The peculiar 



form of the legs in this .species will enable it to be readily 

 identified, at least in the male sex. The posterior femora 

 appear to be ciliate as seen from above, the slender straight 

 tooth at the tip being about as long as the setae. 



2. Xylophilus arthriticus, n. sp. (Plate I, figs. (>, 6a, b, £,- 



legs.) 



cJ. Moderately elongate, broad, robust, shining; black, the 

 trochanters and tarsi testaceous; the head and prothorax densely, 

 the elytra coarsely, punctate; clothed with long, decumbent, 

 cinereous hairs. Head short, broad, narrowly extended on each 

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

 separated by about one-third of their width; antennae moderately 

 stout, joint 2 short, !J nearly twice as long as 2 (the other joints 

 missing). Prothorax convex, broader than long, subquadrate, 

 narrowed in front, unimpressed on the disc. Elytra moderately 

 long, wider than the head, gradually narrowing from a little below 

 the base, the disc with a deep oblique depression, the Bpace between 

 it and the suture appearing tumid. Abdomen clothed with long 

 hairs, broadly excavate and bare down the middle. Legs long; 

 anterior and intermediate femora moderately thickened, the pos- 

 terior pair strongly incrassate and furnished with a broad, pallid, 

 spongy pubescent pad along their lower face ; anterior tibiae (fig. 6) 

 sinuate, dilated towards the base, mucronate at the tip; inter- 

 mediate tibiae (iig. 6a) sinuate, broadly foliaceous, deeply, obliquely 

 emarginate externally; posterior tibiae U J - • M) bowed at the base, 

 and widened and almost straight tnenee to the apex; tarsi rather 

 stout, the basal joint of the posterior pair feebly curved,
