434 Mr. C. O. Farquharson’s Five Years’ Observations 
|The observation on E'piscaphula interrupta Lac, recorded 
in Proc. Ent. Soc. Lond., 1913, p. exxii; 1914, p. xxiii, is 
so curious that further details are added from Farquharson’s 
letter. The first and last sentences refer to a suggestion 
that, as Hrotylidae are fungus feeders, the supposed -cells 
might have been fungi. ] 
Feb. 10, 1914.—It sounds almost like libel to suggest that 
I confused clay cells with a fungus, which some one seems 
to think must have happened in connection with the dis- 
covery of the Erotylids. It is fortunate that Dr. Lamborn 
saw the actual cells. Perhaps the vagueness of my note 
misled them. I may briefly recount the circumstances. 
While examining a stump by the side of a small stream for 
Mycetozoa I came across two small cells of the “ Potter” 
class. Frequently the bottom of these cells is not of clay 
but is simply the flat surface of the object (wall, log, etc.) 
on which the cells are built. Or the cells may only be partly 
“floored” with clay, as if the builder were simply adding 
a little for levelling purposes, so that on prising off a closed 
cell the larva or pupa may easily be seen. The first of the 
two cells that I prised off was of this order, and, as soon 
as it was detached, the beetles started to come out. I 
hastily put the lot, cell and all, nto a closed box. A little 
wood from the stump came away with the other cell, and 
as the “lid” of the “ pot’ was stopped, loosely, I think, 
with débris and not with clay, and nothing tried to get out, 
I simply put it into my vasculum. In the evening, when 
we came to compare notes as usual, I handed the cells to 
Dr. Lamborn. On opening my vasculum I found that the 
Erotylids were just beginning to come out of the sécond 
cell. Of the composition of the cells there was no doubt. 
They were of clay. At the time, I think, we concluded 
that the beetles were aestivating. I think we dismissed the 
idea of their having been stored by a wasp, as they were 
extremely lively on issuing from the cells. I fear I can 
throw no further light on the matter, but I think that if the 
B. M. authorities make such dreadful suggestions I shall 
seriously consider the question of sending any more Myxos !
