Mealy-bug. (?Dactylopius destructor Coms., Ann. Rep. Agric. Dep., 
Ent., for 1880, p. 342, pl. xi, fig. 3; pl. xxii, fig. 2; Man. Entom., 
p. 167, fig. 205.) Figure 179. 
A species of Mealy-bug, which was found on various shrubs and 
trees, apparently belongs to this species, but it was not carefully 
studied and the specimens were not preserved. Possibly it may © 
have been the common Mealy-bug of the greenhouses (DP. adonidum 
(L.) Sig.), in part. The former attacks various trees and shrubs in 
Florida and is very injurious to the orange trees. It is also very 
partial to the coffee-tree. 
Orange Mealy-bug. (Dactylopius citri Bois.) 
Mr. Geo. A. Bishop reports that a Mealy-bug, identified as this 
species, occurs on the orange and other citrus trees in Bermuda, and 
also on various garden vegetables, especially potatoes.

Puate XCVIIL; Ficure 16. 
This elegant species was sent to me living, by Miss Hayward, early 
in September. With it were many minute, yellowish white, ovate 
mites, which seemed to be parasitic upon it. See ch. 38, 0.
