already described ; whereas the males of both kinds, 

 in their last state, become flies ; but neither of them 

 can probably do any injury to the pine plants whilst 

 they are in that form. 



The length of the fly, or male, from the head to 

 the tail, exclusive of the wings and those long hairs 

 which are so characteristic of the flies of this kind, is 

 about the thirteenth part of an inch ; and the length, 

 including the wings when folded one over the other 

 on the back of the fly, exclusive of the hairs before 

 mentioned, is about the eighteenth part of an inch.

Coccus Adonidum. — The Mealy Bug ; White mealy 

 crimson-tinged Insect of Speechley. 



This species differs from the preceding one in not 

 being shield-shaped; it resembles the woodlouse, is 

 reddish, and strewed with white dust. At the sides 

 of the twelve segments of the body it is provided with 

 small tubercles. The male is slender, and gnatlike, 

 with two rather broad wings, and tvvO long brush- 

 shaped .tail filaments. 



This foreign species has become a native of hot- 

 houses, to the great annoyance of plants and gardeners. 

 It attacks a number of species of plants, particularly 

 the soft-leaved dicotyledonous kinds, such as the 

 coffee-tree, Justicia, Ruellia, Cestrum, &c. ; it is also 

 found plentifully on Musa, Canna, Renealmia, &c.
