 narrowed towards the apex , apices not much divergent , suturai 

 and lateral spines rather short and obtuse, the humeral fold 

 moderately developed, angularly produced; costate, interstices 

 plain, each of them with a row of large punctures, which become 

 rather confluent near the base, moreover slightly wrinkled in a 

 transverse direction. Beneath densely punctate, the sculpture 

 being , however , indistinct according to the close silvery white pile , 

 which covers the whole of tlie undersurface , legs included.
