 apical margin very slightly raised, with a broad, strongly depressed 

 space before it, leaving a transverse carina before the depression 

 with a row of hairs springing from beneath it. Second segment 

 with five transverse carinas, including the raised apical margin; 

 the remaining segments very sparsely punctured. Pygidium 

 lanceolate, slightly widened at apex, epipygium forming a median 

 carina. Fifth ventral segment coarsely longitudinally rugose.

 The present species is also much more strongly punctured on the 

 head and thorax.
