 longer and narrower, 4-K) gradually becoming shorter and wider, 

 9 and 10 transverse, II ovate, obliquely acuminate. Prothorax 

 narrower than the head, broader than long, quadrate, the anterior 

 angles dilated into a prominent obtuse tooth, the sides abruptly 

 and obliquely convergent thence to the apex, the disc with a deep, 

 transverse, arcuate impression before the base and a shallow trans- 

 verse groove in front of this. Elytra long, much wider than the 

 head, subparallel in their basal half, the post-basal depression 

 oblique and deep. Legs very slender [intermediate and posterior 

 pairs wanting j.

Hab. Burma, Ruby Mines {Doherty). 



One specimen, in a sufficiently good state of preservation 

 for naming. The laterally dentate, uneven, subquadrate 

 prothorax, the small eyes, and the long, subparallel elytra 

 are characteristic. Two species of the genus [robustior 

 and nigricolor, Pic) have been described from Burma, but 

 they must be different from the present insect. 



21. Xylophilus barbicornis, n. sp. (Plate I, fig. 11, 

 antenna, £.) 



<J. Elongate, narrow, depressed, dull (till denuded); obsoure testa- 

 ceous, the long apical joint of the antennae to near the tip, and a 

 common, broad, post-median fascia on the elytra, fuscous, thi eyes 

 black, the tarsi ilavous; the head and prothorax densely, finely, the 

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

 convex, narrowly extended on each side behind the eyes, the latter 

 moderately large, separated by about their own width, and very 

 feebly emarginate in front; antennae (fig. 11) moderately long, 

 joints 1 and 2 much thickened, 2 short. 3-6 gradually decreasing 

 in length, 3 obconic, narrower and much longer than 2, 7-10 a 

 little wider and strongly transverse, 11 stout, greatly elon 

 as long as 3-10 united, Bubcylindrical, acuminate at the tip, becom- 

 ing thicker towards the base and apex, and closely set with stiff 

 dark setae. Prothorax nearly as long as broad, narrow, with the 

 sides constricted behind the middle, somewhat tumid in front of 

 this, and obliquely convergent in front, the disc almost unim- 

 pressed. Elytra long, wider than the head, parallel in then 



half, with a broad, oblique, deep post-basal depression. Legs long; 

 anterior tibiae armed* with a triangular tooth beyond the middle; 

 anterior tarsi with the basal joint thickened; posterior femora a 



little thicker than the others, furnished with a narrow, den.-ch
