the leaves, where the insects reside. Frequent 
watering with clear water though universally re- 
commended, does not destroy them, neither is the 
application of the sulphur and snuff of any use, as 
directed by Speechley and others. See quotation 
on Vines. 
Thrip. — For description see on Peaches and 
Nectarines. A similar treatment will be required 
to eradicate the Thrip, as laid down for the 
Spiders. 
Cocci. — There are several species of this 
genus, which appear' to infect the Glass- 
houses, some of which are the following : — The 
Coccus Vitis, described on the Vine ; the Mealy 
Bug (C. Adonidum), described on the Goose- 
berry; Brown Turtle Bug (C. Hesperidum) , ge- 
nerally found on Pines, Oranges, Myrtles, and 
various other plants, and which, when fully 
grown, is an irregular ovated brown scaly inert 
insect ; the White Mealy Bug, (I believe, C. Hes^ 
peridum var), much smaller than the last, of a cir- 
cular form, white and testacious, and possesses 
those plants which are subject to the Brown 
Turtle. All these species, while young, ai-e fur- 
nished with several legs, and two antennae or 
horns, all of which, when first excluded from the 
egg, are so minute as to require a magnifying 
glass to discern them. For a few days, till per- 
manently fixed, they will be found to wander over 
the plants pretty actively, and most species, when 
fairly fixed, commence manufacturing a vesture.
