Long. corp. f lin., lat. f lin. 



Oblong-ovate, subparallel, tolerably robust, finely pubescent, flavo- 

 testaceous. Head short, transverse, hardly produced ; immediately 

 above the base of the antennae is a medial longitudinal fovea, which 

 is terminated at its upper extremity by a transverse channel extend- 

 ing at right angles to it between the eyes, these channels forming 

 together the character of the letter T. : eyes large, black, situated at 

 the base of the head, extending laterally not quite so far as the an- 

 terior angles of the thorax : the surface finely punctate throughout. 

 Thorax transverse, the anterior angles depressed, the sides margi- 

 nate; at the base is a shallow transverse depression; the surface 

 finely punctate throughout. Scutellum triangular. Elytra some- 

 what broader than the thorax, subparallel, distinctly punctate-striate ; 

 an antemedial transverse depression gives an appearance of promi- 

 nence to the base ; the surface is clothed throughout with fine and 

 sparingly distributed flavous pubescence. Antennae robust, somewhat 

 incrassated towards the apex, clothed distinctly with several hairs of 

 unequal length at right angles to the joints of the antennae ; the first 

 joint longer than any of the others, and dilated at its apex ; the. 

 second broad, short, ovate ; the third to the sixth of equal length, 

 not longer than the second, and attenuated ; the seventh to the eleventh 

 short and dilated ; in colour, the first to the ninth flavous, the tenth 

 and eleventh fuscous. Legs flavous throughout.
