 Type, Palpoxena Iceta, Baly. 



The large prominent eyes and the dilated third joint of the 

 maxillary palpi in the male sex will distinguish Palpoxena from any 

 hitherto described genus of the family.

Hub. Malacca, Borneo. Collected by Mr. Wallace. 



Head smooth, face subquadrate, nearly the whole surface below the 

 antennae covered by a large, smooth, slightly depressed triangular 

 space, bounded on the sides by a slightly raised margin, the lower 

 portion of the space traversed by a deep transverse depression, whilst 

 its apex extends upwards between the antennae, terminating immedi- 

 ately above the latter in a deep fovea; clypeus nearly obsolete, its 

 place being occupied by the thickened lower edge of the triangular 

 space ; antennae slender, pale fulvous, terminal joint in the male 

 flexuose, acute ; thorax narrowly margined, sides slightly produced and 

 rounded in front, narrowed and sinuate behind, anterior angles pro- 

 duced laterally into an obtuse tooth, the posterior slightly produced, 

 subacute, above moderately convex, minutely but not closely punc- 

 tured, impressed behind the middle of the disk by a broad transverse 

 groove formed by two large transverse foveae placed side by side; 

 Bcutellum fcrigonate, its apex obtuse; elytra oblong, much broader 

 than the thorax, convex, transversely depressed below the* base, basilar 

 space on each elytron distinctly elevated, the raised portion being 

 bounded externally by a longitudinal depression within the humeral 

 callus, and beneath by the transverse depression, surface finely and 

 Bubremotely punctured, interspaces, together with the general Burface 

 of the thorax, minutely granulose-punctate.
