The following changes in nomenclature should be made : — 

 (4.) Dactylopius adonidum^ (Linn^) Signoret. 



Syn. : Dactylopius longispinus, Targ.-Tozz. 



Syn. : Dactylopius longifilis, Comst. 

 (6.) Dactylopius citri (Risso, 1818) Signoret, 1875. 



Syn. : Dactylopius citri (Boisd.) 



According to Berlese the Coccus farinosus^ DeGeer, 1778, is the 



same insect. I have held this doubtful, but if our insect is^really 



identical with DeGeer's, we must call it Dactylopius farinosus. 

 (21.) Lecanium nigrum var. begonim (Douglas). 



Syn. : Leconium begonice, Douglas. 

 (22.) Lecanium nigrum var. depretsum (Targ.-Tozz) Maskell.
