ance. The under, or dark side of the leaves is its 

 residence ; and we have observed a plant in a house 

 where there was only light on one side, with the dack 

 side literally covered, while the light side was clean. 

 So much for having houses with plenty of light. The 

 effects of this insect are of a corroding nature, extract-

 to the other side ; and where they have got to the 

 extremity, the foliage is completely yellow, and of a 

 decayed appearance.

 observed this insect arrive to any extent, but think that 

 the Datura arborea is most infested with it. It is the

 to which it generally adheres, there appear to be hun- 

 dreds of eggs under it, but fumigating completely de- 

 stroys the larvae. In our opinion this turtle insect is 

 no other than the old female of the brown scaly insect, 

 which swells to a large size before depositing its eggs. 

 We have frequently observed the insect dead in this 

 enlarged state, and question if this is the last stage of 

 its transmigration. The male insect is winged, and 

 very active in its movements.

At this period of the season very little is required to 

 grow Calceolarias to perfection. They require a few 

 months of the Hot-house, and if the directions given 

 last month were followed up, some of these will have
