Identification of the Mealybug 
499 
localities throughout the world, previously identified as calceolariae; 
the mame Pseudococcus boninsis (Kuwana) should be applied to 
specimens of an elongate gray mealybug already known to occur on 
sugar cane in many parts of the world and previously identified as 
calceolariae. Some references in literature to the species Pseudococcus 
saccharifolii (Green) and Trionymus sacchari (Cockerell), both 
of which, from the information available, are distinct and valid 
species, actually refer to Pseudococcus boninsis (Kuwana). The 
variety minor (Maskell) of the species calceolariae is identical with 
Pseudococcus citri (Risso). 
The various species involved under the name calceolariae may be 
recognized from the detailed descriptions and from the key given in the 
body of the paper, while , all of the mealybugs definitely known to 
occur normally on sugar cane m^y be separated by this same key.
