short stiff dark hair, and three more on each side behind, 
equidistant ; none on the anterior part. Hairs of the disk 
similar to those of marginatus. 
Lamellae nearly horizontal, broadest in front, though the 
actual extremity is narrowed a little. Cusp blunt, front 
margin slightly concave. Towards the extremity a rough 
seta springs from below the outer rim and curves round in 
front, nearly in contact the whole way. The vertex rises into 
a low rounded ridge in the middle which is continued to the 
rostrum. Pseudostigma prominent, placed well forward ; 
pseudostigmatic organs short and heavily clubbed, reflexed ;
