deeply emarginate, not reaching the base of the head, and well 

 separated ; antennae very long, joints 1-3 rather slender, 3 minute, 

 smaller than 2, 4-11 moderately stout, 4 longer than 2 and 3 united, 

 4-10obconic, gradually decreasing in length, 11 obliquely acuminate. 

 Prothorax small, a little broader than long, subquadrate, obliquely 

 narrowed in front, the disc with a transverse depression before the 

 base. Elytra flattened, moderately long, wider than the head, 

 subparallel, blunt at the tip, with an oblique post-basal depression. 

 Legs long; anterior tibiae feebly curved, mucronate at the inner 

 apical angle ; posterior femora feebly curved, moderately incrassate,- 

 simple. 



Length 1^-2, breadth § mm.

Two males — -one immature and almost wholly testa- 

 ceous (the posterior infuscation of the elytra, however, 

 is still visible), the other, from which the description is 

 taken, apparently mature. The very long antennae in <$, 

 with minute third joint and the small prothorax, bring this 

 species near X. melanosoma from Borneo * and X. parvicollis 

 from Tenasserim. Compared with the former, the antennae 

 are less serrate, the eyes smaller, the elytra less rounded 

 at the tip and flatter, the body differently coloured, etc." 

 X. 'parvicollis, $, has shorter antennae, a longer head, 

 more prominent eyes, differently coloured elytra, angularly 

 dilated posterior femora, etc.

Oblong, somewhat depressed, shining (when denuded); rufo- 

 testaceous, the elytra with a common, indeterminate, broad, dark 

 brown median fascia, the posterior femora and joints 4-10 of the 

 antennae slightly infuscate, the eyes black; densely, finely, the 

 elytra a little more coarsely, punctate ; finely pubescent. Head 

 moderately large, narrowed and considerably developed on each 

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

 separated by less than their own width; antennae moderately 

 long, joints 2 and 3 narrower than those following, these latter rather 

 stout, 3 very small, shorter than 2, 4-9 about as long as broad, 

 10 transverse, 11 ovate. Prothorax much narrower than the head, 

 slightly broader than long, subtrapezoidal, abruptly, obliquely 

 narrowed in front, the anterior angles somewhat tumid, the disc
