Section Yellow Cam Wood is wood of Baphia nitida, a tree 

 growing in Sierra Leone to the height of forty or fifty feet. 

 About three or four hundred tons are annually imported. It is of 

 a deep red colour, and yields a brilliant but not permanent dye, 

 and dyers use it in the same way that they do the dye of another 

 species of the same genus, Brazil wood. There is a beautiful 

 plate of Baphia ?iitida in " Bot. Cat," Vol. IV., p. 367. The 

 flowers are yellow and somewhat similar to our yellow laburnum ; 

 hence its name (I suppose), Yellow Cam wood. The same wood 

 is sometimes called Bar-wood in commerce. E. E. Jarrett. 



Aspidiotus Nerii.— If the scale is removed from the leaf when 

 it is just beginning to harden, it will be found to be full of eggs. 

 It is a very beautiful object to see something like 200 eggs of a 

 rich brown colour all closely packed together. At this point the 

 legs of the parent are still visible, and may be noticed slowly 

 moving backwards and forwards, while the whole of the internals 

 seem to have become eggs. A little older specimen of scale will 

 show the nest or back of the parent full of living young, whose 

 first business is to eat up the parent's legs, and then go off explor- 

 ing on their own account. There are, I think, always some few 

 eggs not hatched, which is probably owing to the loss of heat 

 through the final decease of the parent and the emptying of the 

 body caused by the roving of the rest of the family. If undis- 

 turbed, the young seem to stay about the old " home " for a day 

 or two, until they have lost all traces of the downy " packing," 

 which always adheres to them at first. 



If any member is troubled with his gardener's negligence 

 about cleaning off the scales, let him show the inside of a good 

 hard specimen, under a pocket-lens, to him. It will have more 

 effect than an hour's talk. (This recipe is recommended after 

 trial.) There are two red eye-spots on the young when hatched, 

 but I do not think they are of any practical use. The head is not 

 particularly marked off from the body, so far as I have been able 

 to make out. H. R. Boult. 



Tingis hystricellus.— With this slide I enclose a cutting from 

 Science Gossip, 1869 : — 



" This new and very interesting hemipterous insect, to which 

 I have given the name of Titigis hystricellus, was discovered in 

 Ceylon and collected from the Bringall plant by Mr. Staniforth 

 Green, a gentleman long resident in that island. All the species 

 of the genus to which it belongs are small, but the present species
