Long. corp. 2^ lin., lat. li lin. 



Oblong-ovate, subparallel, subcylindrical, covered throughout with 

 a pale yellow silky pubescence. Head transverse, produced broadly 

 in front : from the sides of the labrum two oblique carinations extend 

 upwards, joining one another immediately below the base of the 

 antennae ; the transverse triangidar plane which is thus formed is 

 bisected by a medial longitudinal ridge : the eyes are large and pro- 

 minent, situated at the base of the head : the surface is finely granu- 

 lated, and pubescent at the base ; black, the base (between the eyes) 

 being rufo-ferrugineous. Thorax elongated, the anterior angles 

 attenuated and depressed ; at the base is a broad transverse depres- 

 sion ; the surface (which is black) is clothed at the sides with a pale 

 flavous pubescence. Scutellum triangular, fuscous. Elytra parallel, 

 subcylindrical, punctate-striatc, the striae being almost concealed by 

 a thick silken pubescence of a pale flavous colour. Antennas, robust, 

 filiform (with a slight tendency to dilatation) ; the first joint is ovate 

 and broad ; the second shorter ; the third and fourth fine, of equal 

 length, and slightly longer than the first ; the rest (the fifth to the 

 eleventh) robust, of equal breadth, and slightly shorter than the 

 basal joint ; the colour pale ferrugineous. Legs pale flavous, the an- 

 terior tarsi being suffused with fuscous.

 antennae is a transversely triangidar plane ; above the base of the 

 antennae and between the eyes are two minute contiguous tubercles ; 

 the eyes are prominent and black ; the surface is finely granulated,
