Bairstow to illustrate the changes of appearance of the 
specimens under observation, the first showing the 
general appearance in an early stage of development, 
the second showing the patchy appearance of the fine 
growth of the flocculent covering. 
From my own examination of the larva in the first 
stage (figured p. 9), as seen after being in a preservative 
fluid for some time, it was of a reddish tint, with black 
legs and antennae and black eyes, and was furnished at 
the tip of the abdomen with six long fine hairs. The 
horns at this stage appear to me to be formed of five 
joints and a club. The lowest joint broad and short, 
about half the length and twice the width of the 
succeeding joint, and broadest at the farthest end from 
the head ; the following four joints are almost cylindrical, 
the second of these being longer than the first and 
slightly contracted at the centre; a very few long scat¬ 
tered hairs were observable on the joints of the horns, 
besides those figured by Mr. Bairstow at the extremity, 
but I did not find the antennse hairy throughout, as in 
the first fig., p. 9. For magnified figure of the larva of 
I. purchasi in S. Australia, photographed from life by 
Mr. Crawford, see p. 15. 
On Jan. 23rd Mr. Bairstow placed two females on 
trees, and on the 31st, and up to Feb. 3rd, many young 
hatched. A large number of these were killed to keep 
the number for special observations in bounds; but on 
Feb. 1st, 157 newly-hatched little “bugs” were counted. 
Those that fell seemed unable to regain position [an 
important point practically— Ed.] ; those on the trees 
were excessively active, anxiously running all over the 
plant, as if desirous of making lodgment. Towards 
evening they appeared darker and somewhat glistering 
with rough whitish particles. On the following day 
(Feb. 2nd) many were dead, and the survivors mostly in 
parties on leaf-stems, those nearest the roots preferred. 
Mr. Bairstow notes that they have “ begun to assume 
a white appearance, which, under dissecting small power 
monocular microscope, consists of six clumps or clusters
