2. Hylobaenus fractieornis, n. sp. (Plate I, fig. 2, 

 antenna, <$.) 



cj. Moderately elongate, shining; piceous, the palpi and legs 

 (the infuscate posterior femora excepted), an elongate-triangular 

 patch on the disc of the elytra before the middle (extending forwards 

 to near the base), and a small spot near the suture before the tip, 

 testaceous, the antennae with joints 1 and 2 and 8-11 rufescent, 

 the others almost black; clothed with fine, sericeous, cinereous 

 pubescence ; head and prothorax densely, finely, the elytra a little 

 more coarsely, punctate. Head strongly deflexed; eyes very large, 

 contiguous ; antennae moderately long, stout, joint 2 shorter than 1, 

 subcylindrical, about as long as broad, 3 triangular, about as long 

 as 2, 4-7 abruptly wider and very strongly transverse, 8 nearly as 

 long as 5-7 united, sublunate (narrow at the base and arcuately 

 dilated at the apex within, the concave inner portion pilose), 9 and 

 10 subquadrate, 11 ovate. Prothorax broader than long, convex, 

 somewhat uneven, subparallel-sided, and feebly constricted at the 

 base. Elytra much wider than the head and prothorax, subparallel, 

 broadly and obliquely depressed on the disc below the base, and 

 somewhat tumid near the suture anteriorly. Legs moderately long, 

 slender, the posterior femora strongly clavate; anterior tibiae and 

 basal joint of posterior tarsi almost straight ; posterior tibiae bowed, 

 slender.

Hab. Assam, Patkai Mts. (Doherty). 



One male. The extraordinary structure of the <§ 



, antenna is unique, so far as I am aware, amongst the 



Xylophilids, though there is a minute New Zealand form 



(X. luniger, Ch.) with the seventh antennal joint somewhat 



similarly shaped in the same sex. 



3. Hylobaenus varicornis, n. sp. 



Moderately elongate, robust, shining; piceous, the palpi, legs 

 (the infuscate posterior femora excepted), and apex of abdomen 

 testaceous, the basal and apical margins of the prothorax, and 

 joints 1, 2, and 11 of the antennae, rufous; densely, finely punctate, 

 thickly clothed with greyish, sericeous pubescence. Head strongly 

 deflexed; eyes very large, contiguous; antennae stout, moderately 

 long, joints 1 and 2 much thickened, 3 scarcely longer than 2, 3-10 

 gradually becoming a little wider and more angular, 11 ovate. Pro- 

 thorax convex, about as wide as the head (including the eyes),
