EemarJcs. This exudation is said to be produced by the puncture of the 

 Coccus maniparus. It is often called Arabian Manna to distinguish it 

 from Toorunjabin, or Persian Manna, secreted by Alhagi maurorum, 

 Tourn. N. O. Leguminosse ; Shirkist, or Khorassan Manna, said to he 

 the product of a species of Olive ; and Sicilian Manna the sweet concrete 

 exudation of Fraxinus Ornus, Linn, and F. rotundifolia, Linn, both 

 Oliveworts. Australian or Gum-tree Manna is a spontaneous exudation 

 from Eucalyptus mannifera, Moudie (Trans. Med. Bot. Soc. iii. 24), 

 N. O. 85. Myrtacese. Bennett states that the Eucalyptus viminalis of 

 Hooker is the source of Australian Manna, and that it is produced by the 

 perforations of a Tettigonia. He also states that a saccharine and muci- 

 laginous substance, called Lerp by the natives, is produced on Eucalyp- 

 tus dumosa, A. Cunn. by a Psylla. In a note to chapter viii. of Living- 

 stone's Missionary Travels, it is said that a sweet gummy exudation called 

 by the aborigines of New Holland Woo-me-la, is produced by a species of 

 Psylla on a species of Eucalyptus. Is this Lerp ? In the chapter quoted, 

 Livingstone mentions that the larvae of a species of Psylla appear in South 

 Africa on the Mopane tree (Bauhinia sp. ? N. O. 74.) covered with a 

 sugary secretion, which the inhabitants collect and eat. At the Cape 

 of Good Hope, Vascoa amplexicaulis t De C. has a saccharine root,
