In this country Ihave not found this to be the case upon the naked-bodied species, Lecanium,etc. But some of the Diaspidte, particularly MytUaspis pomorum, have oftenin their shells minute white Acari; and as in these cases many of theenclosed eggs have been shrivelled or empty, I imagine that the Acarus maydevour them. The insect I am now describing attacks some of the indigenous test-bearing Coccidte. When in June, 1877, I found my first specimens ofCtenochiton perforatus, I did not at first understand the nature of an object. ,
