Black, moderately shining. Head finely and sparsely punctured 

 on basal portion, coarsely and more closely on rostrum. Eyes 

 prominent, vertex with a deep and somewhat extended puncture 

 between and above eyes, diameter of head across eyes over one 

 third greater than greatest breadth of rostrum. Rostrum shorter 

 than half the length of thorax, basal portion shorter than apical, 

 broader than long, with straight and parallel sides, apical portion 

 but slightly dilated and broader than long. Joints of funicle of 

 antennse barely wider externally, the outermost one half width 

 of club. 



Prothorax longer than broad, oblong, base bisinuate, sides 

 rounded and constricted at base, straight or but feebly arcuate 

 for middle three fourths, thence arcuate to slightly constricted 

 apex. Surface convex and but slightly flattened above, coarsely
