(placed as in right-hand fig., p. 9), one clump near head, 
followed by two clumps, and again two, and one anally. 
To my great astonishment there protruded from anus 
of each a long thread-like appendage, white and brittly, 
which terminated in a rotund pellucid drop of liquid 
This, unlike water, did not disperse on glass, but appeared 
to consist of a semi-solidity which could be divided as 
mercury with a lancet. On casting one globule against 
another no fusion ensued. No change in antennae. 
“ Feb. 3rd. Filaments produced in different insects, 
ranging from in. to J in. long. Some collided together 
at liquid point; others crossed at irregular angles. In 
a few the globule was absent, but filaments seemed 
much more produced, reaching f in. Clumps not now 
divided, hut welded together, showing form only of prior 
division. Bugs assuming a white cottony appearance or 
glistering, as of small particles of ripe apple. Antennae 
still knobbed, and all externals as before. No moult 
evident. Bugs stationary, almost inactive, barring slow 
leg movement. Many with ; filaments quite removed. 
Others mixed up indiscriminately together. Bugs about 
twice size, nidus included, to naked eye as when hatched. 
“Feb. 6th. First moult takes place in some. Discard 
white, ragged, broken cases (in metamorphosis), which 
are visible here and there. Present form evidently 
more matured, and body takes a yellowish hue, which 
permeates the white dorsal tufts. Filaments mostly 
fragmentary; antennae still knobbed.”* 
* Mr. Bairstow continues, still on Feb. 6th, regarding a different form 
of larva noted as “ condition 2 ” :—“ Thus far first moult. Simultaneously 
I observe another form (whether allied or distinct remains to be proved), 
. . . which I shall describe roughly in contrast: Not tortoise-shaped 
like their seniors, as suggested by Trimen, but louse-shaped; segments 
conspicuous whitish yellow (light lemon), legs pale, antennae not knobbed, 
incilate ringed; lateral and anal hairs diminished, replaced by irregular 
tubular excrescences. More active, and not sticking to leaves.” On the 
10th these are noted as “ active, and appear very white to naked eye ” ; 
and on the 16th this second condition or form is noted as “ very 
gregarious, stationary, in clumps fixed on top of one another; no 
change, but growing.” 
On the 22nd Mr. Bairstow notes these larvae distinguished as No. 2 
being “ as before, but parents raised on ovaries ” ; on March 10th, that 
eggs from No. 2 had hatched, mothers shrivelled.
