the frog’s caution was soon evident. The watchman also 
suddenly became acutely conscious of it. The surface of 
the ground was swarming with soldier Termites, and a 
bellicosus soldier gives a rather severe bite. After a time 
the swarming ended and the soldiers disappeared under- 
ground again.

Oct. 18, 1917.—During September there were to be 
seen on the Pard trees colonies of curious little creatures 
that appear to me to be related to Psyllidae or some nearly 
related group. At first they are wingless and sit and feed 
crowded together in a circular mass about the size of a 
crown piece or even larger, apparently in defiance of 
Ocecophylla. They. retain the gregarious habit till they 
become winged, after which I-think they must separate. 
The imago after the last change is at first whitish in colour. 
In the mass they are by no means conspicuous. Just 
to-day I came across yet another curious colony, very 
like young Psyllids but protected by a thin silky web. 
I hope to get a few mature forms with good luck. Under 
the web are enormous numbers of eggs, of oval shape. I 
sent you one or two of the first group and will send more 
later.

Feb. 4, 1918.—I am sorry that they were in such bad 
condition, for they are the most dreadful beasts to put up 
that I’ve yet tried. That was why I put some in spirit— 
immature forms—though I had another reason too, of 
which I'll tell you. I wished to let you see that they 
had abdomens, for they shrink terribly in drymg. When 
alive they are miserably soft and delicate creatures, the 
slightest pressure causing them to burst. They are like- 
wise very difficult to catch, not because they take alarm 
and fly: they don’t, but they refuse to leave the bark 
of the tree. The net cannot be used, and when one puts
