them. 
The timbers of British Guiana, it is true, have not as yet profited to

sive, and attractive, as was that shewn by the Japanese, might be of ser-

notions" in timber. 
A New Entomogenous Fungus from British Guiana — . 
A remarkable fungus growing on a large black ant

the banks of the Puruni, has recently been described 
and figured in the Annals and Magazine of Natural

Botanic Gardens, Jamaica. The specimen was the only 
one met with by Mr. Lloyd, though he has collected

same species of ant in Brazil is infested with another, 
but closely allied, fungus ; while the new fungus bears a 
great resemblance to, and possibly is identical with, a 
species described from New Guinea, where it grows npt 
on an ant, but on an entirely different insect, viz., a 
Coccus or Scale-insect. It appears that the fungus 
attacks the ant while it is living, and that the fine basal

ultimately attach the ant to the leaf on which it
