In a paper read before the Linnean Society in May 1868 *, I 
showed that the tree on which feeds a larva spinning cocoons 
from which large quantities of silk are manufactured in the 
north of China is Quercus mongolica, Fisch. ; and I gave reasons 
for the opinion that Q. dentata, Thunb., is also used to feed the 
same worm. When writing this paper, I had accidentally over- 
looked a valuable article by Dr. D. B. M‘Cartee * On some Wild 
Silkworms of China," published in the ‘Journal of the North 
* Journ. Linn. Soc., Bot. x. 482.
