vated within the shoulders and below the basilar space, humeral 

 callus moderately prominent ; surface rather coarsely punctured, 

 tlie punctures arranged in numerous longitudinal rows, which 

 approximate in pairs ; on the outer disk, running parallel to 

 the lateral border, are two elevated vittae. Subhumeral tubercle 

 prominent.

Front separated from the epistotne and encarpae by a broad 

 deeply sulcate groove ; surface somewhat distantly punctured, 

 impressed with a longitudinal groove, which, commencing at the 

 vertex, terminates anteriorly in a deep wedge-shaped rugose ex- 

 cavation ; anterior margin trilobate, the two lateral lobes indis- 

 tinct, broad and very obtuse, the medial one narrow, angulate, 

 moderately produced ; epistome broader than long, sides obliquely 

 converging backwards, rounded posteriorly ; surface distinctly 

 ])unctured, not rugose, plane in front, the upper portion 

 gradually shelving to join the frontal groove ; encarpae broadly 

 cultriform, their surface smooth, the hinder portion raised and pro- 

 duced upwards into a distinct obtuse process; antennae rather more 

 than half the length of the body, five upper joints moderately 

 dilated, black. Thorax one-fourth broader than long; sides 

 rounded and converging from base to apex, above transversely 

 convex, sides deflexed in front, coarsely but remotely punctured. 

 Elytra broadly oblong, excavated below the basilar space ; humeral 

 callus moderately prominent, bounded within by an indistinct 

 longitudinal depression ; surface coarsely punctured, punctures 

 arranged in longitudinal rows, which are irregular and ill-defined 

 on the disk, but have a tendency to approximate in pairs near 

 the apex of the elytron and on the outer disk ; two alternate inter- 

 spaces near the outer margin are distinctly costate.
