might not have evolved through such forms, and of course 
didn’t take the time I ought to have taken over them. 
It is a dreadful lesson and I feel so intensely annoyed 
about it. The only Psocids ve ever seen—and I grieve 
to say I took little note of them—were under cover-glasses 
in Canada balsam—amicroscopic things. I will try to get 
more and work out the hfe-history. 
Feb. 14, 1918.—It is remarkable that such wretched 
soft-bodied animals can live on the same trees as Oecophylla 
with no protection at all in the way of silk.

[Between 1913 and 1915 Farquharson made many 
valuable observations on the life-histories and habits of 
Aculeate Hymenoptera at Moor Plantation; but this work, 
with the exception of the following, was undertaken under 
the direct influence of his friend Lamborn, and its publi- 
cation is better deferred until their joint labours can be 
communicated to the Society. It would not be right to

May 28, 1915.—You will have begun to wonder whether 
I am ever to send you any insects at all. It is not that 
I have not tried to get something done, but up till now I 
have had very little success, partly from mistakes in 
technique, partly from ill-luck, but in the main from lack 
of time. My chief bit of ill-luck was with Paltothyreus. 
One morning after a tornado I noticed a large winged ant 
apparently looking for a nesting-place. I put her into a 
tin and got her up to the laboratory; I got ready a glass 
jar with some sand and small stones and cautiously opened 
the lid of the tin. She had dropped her wings, which I 
have kept. I put her into the jar and in no time she 
started to dig herself in. I put live earthworms into the 
jar, but these also dug themselves in, and as far as I could 
see, she made no attempt to attack them; in fact, for her
