248 Supplementary Note. 



SUPPLEMENTARY NOTE. 



In the recently published ' Catalogue of the Coccidte of the World,' by Mrs. 

 M. E. Fernald (Hatch Experiment Station of the Massachusetts Agricultural 

 College, Bulletin No. 88), the genus Lecanium has been extinguished, giving 

 place to the older name Coccus (type L. hesperidum). The genus (as formerly 

 defined) has also been broken up into a number of subgenera, proposed princi- 

 pally by Prof. Cockerell. According to this catalogue the species described in 

 the present part would be known by the following names : 



Coccus cappatidis. Coccus acutissimtis. 



Coccus hesperidum. Coccus anindinarice. 



Saissetia formicarii. Coccus longulus. 



Coccus fronttde. Coccus caudatus. 



Coccus ophiorrhizce . Saissetia psidii. 



Coccus aciiininalus. Saissetia olece. 



Coccus signiferus. Saissetia nigrum. 



Coccus viridis. Saissetia hemisphccricum. 



Saissetia discrepans. Paralecanium expa?isu)ii. 



Saissetia punctulifericin. Paralecaniutn fnarginatitm. 



Eticalymnatus subtessellatus. Paralecanium geometricum. 



Eucalymnatus tessellattts. Paralecariium calophylli. 



Coccus antidcsma. Paralecanium peradeniyense. 



Coccus piperis. Paralecanium planicm. 



Coccus inarsupialis. Paralecanium zonatum. 



Coccus hicruciatus . Paralecanitcm maritimum. 

 Coccus mangifercc. 



Other subgenera, not represented in Ceylon, are : 



Slictolecanium, Ckll. (type S. ornatum, Hempl.) 

 Mesolecanium, Ckll. (type M. nocturman, Ckll. and Parr.) 

 Neolecanium, Parr, (type N. imbricatum, Ckll.) 

 Akermes, Ckll. (type A. bruneri, Ckll.) 

 Toumeyella., Ckll. (type T. mirabilis, Ckll.) 

 Eulecanium, Ckll. (type E. tilice, Linn.) 

 Megasaissetia, Ckll. (type M. injlata, Ckll. and Parr.) 

 Platysaissetia, Ckll. (type P. Castilloes, Ckll.) 



There is no doubt that the genus Lecanium had become unwieldy and 

 required sub-division ; but it is doubtful whether all of the proposed subgenera 

 represent really natural divisions,
