destroyed by a small hemipterous bug ; I could only secure one specimen, which was in 

 the larval stage ; I kept this in a cage and fed it on the larva? of Nematus ventricosus. 

 and after a time it produced Podisus modestus. Two other species of insects were noticed 

 by me harrassing them, but I could not secure specimens : a larger Hemipteron, and at 

 Dalhousie a species of Ichneumon fly about half an inch long, black, with red legs. 

 Where single trees are grown as specimens on lawns, or as ornamental trees by the sides 

 of roads and streets, they may be protected by showering them with Hellebore or Paris- 

 green, in liquid mixtures ; or, where the clusters of young larva? are within reach, a blow 

 with a flat instrument as the blade of an oar or a paddle will knock them off the branch, 

 and thus a whole family of larva? may be despatched at one stroke. Two of the trees in 

 the row I have mentioned, which were planted by Mr. Stewart at Dalhousie, were kept 

 clean by this simple means, the young larva?, evidently getting lost among the tall grass 

 un ler the trees, were thus prevented from climbing up again and attacking the foliage.
