heavy, with a double row of pores on each half. 
This species has been described from eight specimens mounted 
on slides. No satisfactory material of any other stage has been

types are in the United States National collection of Coccide. 
The small size of this species, its peculiar ridging, and the very 
numerous submarginal gland tubercles seem to be characteristic, 
and to separate it from any other member of the genus known 
to me.
