 sinuate, sides subparallel to about middle, thence rapidly 

 narrowed to apex, where there is a slight constriction ; upper 

 surface plane, with a broad, deep, triangular impression ex- 

 tending from the apical constriction to base^ the impression 

 being rugosely punctured and containing a broad impunctate 

 carina throughout; the portions of the disk adjoining the
