In the first paper of the work above referred to (Hetero- 
gyna and Fossores to the end of Pompilidae) Mr. Saunders 
expressed his hope that I would follow it shortly with one 
upon the Sphegidae. But on attempting to do so, I soon 
discovered that I was undertaking a task to which I was 
unequal, and so we agreed instead that he should go on 
at once to the other parts of his subject (the Diploptera 
and Anthophila) and publish his account of them without 
waiting for the completion of my paper. Later still, to 
my great relief, he consented to a further modification of 
the plan: that I should continue the work gradually till 
his other papers had appeared, after which he would 
co-operate with me in finishing it. So the matter stood 
when, in 1908, Saunders’s third paper (the Anthophila) 
appeared in these Transactions; and we then definitely 
settled arrangements for a division of labour, Saunders 
undertaking certain Genera, and I others, with the idea of 
speedily publishing a joint-paper which should form the 
concluding part of the entire series. 
Saunders’s illness and death made it impossible to carry 
out the plan as it was intended ; but he was at work upon 
his share of it up to the last. He had practically com- 
pleted several “ Descriptions of new species,’ which were 
found among his papers, and appeared in the Society’s 
Transactions for 1910, Part IV. He had also drawn up 
an annotated list of all Mr. Eaton’s insects (except a few 
which at the time were in my hands for determination) 
and had included in it certain of my own specimens, 
which he had examined and taken note of before leaving 
home. The annotations were mainly records of localities 
and dates of capture copied from the labels pinned under 
the specimens. Others were extracts from a MS. diary
