Mealy-bug. {? Dactylopius destructor Corns., Ann. Rep. Agric. Dep., 

 Ent,, for 1880, p. 342, pi. xi, fig. 3; pi. 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 (D. 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.

This elegant species was sent to me living, by Miss Hay ward, early 

 in September. With it were many minute, yellowish white, ovate 

 mites, which seemed to be parasitic upon it. See ch. 38, 5.

The body is dark brown, strongly grooved transversely; it bears a 

 central double row and a marginal rosette of pure white scale-like 

 secretions; posteriorly these become much elongated in the adults
