irregular longitudinal rows ; on the outer disk in the $ , com- 

 mencing immediately below the humeral callus, are four strongly 

 raised longitudinal vittae ; two, parallel to each other and to 

 the outer border, unite before their apex and terminate at the 

 suture in a large common tuberosity ; the third, parallel to the 

 former two, ends halfway between the middle and apex of the 

 elytron, whilst the fourth, placed still more inwardly towards the 

 middle disk, is very short and scarcely extends beyond the middle 

 of the elytron ; on the shoulder are four or five oblong tubercles 

 or ridges,

Head coarsely punctured ; epistome triangular, truncate at its 

 apex and separated from the face by a distinct sutural groove ; 

 surface closely punctured ; face impressed with a well-defined longi- 

 tudinal groove ; anterior margin angularly lobed, sinuate on either 

 side, lateral angles distinct. Antennae nearly equal to the body 

 in length in the $ , five upper joints very slightly dilated, gradually 

 increasing in width from the seventh to the nmth ; in the $ they 

 extend rather beyond the anterior half of the body, the five outer 

 joints broader and forming a distinct though narrow club. Thorax 

 transverse, sides rounded, hinder angles armed with a short tooth; 

 above transversely convex, sides deflexed in front, surface finely
