sides, the dorsal depressions shallow, the anterior one 

 faintly indicated; the ^-characters wholly different. The 

 colour of the elytra is considerably modified by the close, 

 fine, grey pubescence. The narrow, ciliate, flavous pad 

 on the posterior femora (which i.s wholly wanting in the 

 same sex of X. malaccanus) extends for about one-third 

 their length.

(J. Elongate, s u I > parallel, shining (when denuded); nigro-piceous, 

 the head, prothorax, a large humeral spot on the elytra, and the 

 femora and tibiae (the posterior pair in part excepted), rufous or 

 rufo-testaceous, the palpi and tarsi testaceous, the antennae rufo- 

 piceous, with joints 1, 2, and 11 testaceous; closely, finely, the 

 elytra more coarsely, punctate; clothed with fine, grey, sericeous 

 pubescence. Head short, broad, convex, considerably developed on 

 each side behind the eyes, the latter moderately large, feebly eniargi- 

 nate, and separated by a little less than their own width; antennae 

 long, rather slender, joint 2 short, 3 much longer, 3-10 subequal 

 in length, subtriangular, 11 acuminate-ovate. Prothorax much 

 narrower than the head, subquadrate, abruptly, obliquely narrowed 

 in front, strongly constricted on each side behind the tumid anterior 

 angles, the disc with a deep, transverse, arcuate fovea near the 

 base and a transverse groove in front of it, the latter extending out- 

 ward to the lateral constriction. Elytra long. Bubparallel, wider 

 than the prothorax, somewhat convex, the post -basal depression 

 deep. Legs long, not very slender; anterior tibiae thickened, feebly 

 sinuate, slightly curved; basal joint of anterior tarsi elongated, stout ; 

 intermediate tibiae sinuate, somewhat curved; posterior femora 

 moderately incrassate, distinctly curved, simple; posterior tibiae 

 dilated in their outer half within; basal joint of posterior tarsi 

 long, a little curved, more than half the length of the tibia.

The male described seems to be a variety of X. malac- 

 canus, Pic (the type of which was found by Doherty at 

 the same locality), with a ferruginous humeral patch. To 

 judge from the description, the sinuate sides of the pin- 

 thorax and the strong transverse depression on the anterior 

 portion of the latter agree better with the present insect 

 than with X. glaucus, which is from the same source.
