(8s) 
by which his name will be chiefly known was published in 
1870, ‘‘Ichneumonidum Britannicorum Catalogus,” followed 
by the valuable monographs on the British Parasitic Hymen- 
optera, which appeared in the Transactions of this Society 
between 1872 and 1889. He published an important volume 
on a portion of the raconide in André’s “Species des 
Hyménoptéres d’Europe,” and was still at work on the subject 
at the time of his death. He was an accomplished draughts- 
man and a clear and admirable writer. The loss of so able 
a student of an important but much-neglected group will be 
long and deeply deplored.* 
Puinie Brookes Mason, M.R.C.S., F.L.S., F.E.S., a Fellow 
of our Society since 1874, died on November 6, 1903, at 
Burton-on-Trent. His death is a sad loss to his profession, to 
the neighbourhood in which he laboured, and to a wide circle of 
naturalist friends. Mr. Mason was born at Burton on January 
2, 1842. After a medical education of unusual distinction 
and variety of valuable experience, he made his permanent 
home at his native town in the Midlands. The British fauna 
and flora formed the chief interest of his life, and he possessed 
magnificent collections of both. With his sympathetic genial 
nature, it was his delight to welcome his brother naturalists to 
share in the well-nigh unique advantages which he possessed. 
And as he was a skilled and honoured member of the healing 
profession, so he was ever ready to lend the weight of his 
influence and the power of his persuasion to promote peace 
and friendliness. As the Society concerned with the branch of 
natural history to which he was chiefly devoted, we recognise, 
with grief, that a strong influence for good has _ passed 
from us.+ 
Joun Sanpers Stevens, F.E.S., became a Fellow in 1862. 
His death at Woking, on July 15, makes a sad break in 
the ranks of the senior Fellows of the Society.
