On Feb. 16th the young hugs again moulted. The head 
portion first exposed, and in many instances the old 
whity abdominal skin remained a whole day attached. 
The colour was now salmon-red; legs and horns (which 
last were still knobbed, but have a more rugged appear¬ 
ance) black. 
On Feb. 22nd Mr. Bairstow remarks of these same 
larvse :—“ Should imagine ‘ condition 1 ’ has undergone 
a further moult, but invisible or overlooked, as I find 
fig. 8” [of illustrations sent to me, E. A. 0.] “in two 
forms, one of which is very active, and antennae knob¬ 
less, conspicuously segmental, whilst the other is 
stationary, with antennae slightly knobbed, legs inserted, 
only partially visible, and bases buried in a curly hairy 
mass. 
“Feb. 27th.—All moulted to knobless antennae. 
“ March 10th.—Condition 1 (fig. 8) growing rapidly. 
Antennae embedded in curly nidus, and legs diminished 
in comparison with swollen body. Beneath many I 
find a young spider-like creature or bug similar to 
that of first emergence, but perfectly white, almost 
transparent.”* 
On March 21st another moult took place to a deeper 
salmon-colour than in the preceding stage, the bugs 
being active at first, and afterwards more stationary. 
Absence from home put an end to Mr. Bairstow’s further 
observations on these specimens. 
* Mr. Bairstow considers it possible that these small larvre are from the 
eggs of the form he has mentioned as “ condition 2,” and that, if this is 
so, “ condition 2 ” produces from eggs two forms, one its own image, but 
very small, the other approximating in shape the young first form of 
cond. 1 (vide first fig., p. 9). 
Not having the opportunity of personal investigation, I do not venture 
to offer any opinion on the above, but merely submit the notes of a 
practical observer; if these experiments were gone over again in the light 
thrown by the minute investigations reported in Prof. Kiley’s paper, it 
appears to me that we might find that some referred to the “ intermediate 
form of female larva” recorded there as not having been previously 
noticed, and that prolonged observation might have shown that the 
small larva differing in absence of colour from the others was that of the 
male insect, which has not yet been described in its earliest stage. A 
repetition of the observation after study of the full history would be 
very desirable.
