their charges, and absorb these drops, they getting a more 
general supply than usual owing to the alarm occasioned 
by the intrader. 
Though I have kept many of the parasitised pupae of 
the Homoptera none ever reached the perfect stage, but 
sickened and died, simply because they were shut up; nor 
have I seen a cast skin with the white web thereon, but 
the old skin disappears, bemg removed by the ants or 
blown away by the winds. I don’t even know whether 
an afflicted larva will reach the pupal stage, but consider 
it highly probable that these changes do take place, for 
the insects with one or two parasites attached were always 
lively enough, but those with four or more were certainly 
not very frisky. Most of the affected pupae seemed to be 
smaller than those which were free. The Jassidae are 
restless creatures and cannot be confined and studied like 
the Fulgoridae and their parasite; they do not appear to 
feed in captivity, and soon become sickly and die, so I did 
not follow up this interesting subject, owing to want of 
- time. 
A caterpillar does not necessarily remain upon the same 
host, more than once I have seen one wandering about 
amongst the other insects, and in boxing them in situ 
they often dropped and hung by a thread; a few of 
mine crawled away, and of these one or two moulted, yet 
if they are undisturbed I do not think they leave their 
friends in order to shed their skins, owing to the manner 
in which they are cast, for the skin is not wrinkled or 
rolled up, it breaks away underneath, and in slowly 
loosening and coming off fairly well retains its shape; the 
skin in the larval cocoon cannot be said to be cast, the 
insect crawls out of it, if any of the cocoons be opened 
the perfectly shaped skins will be found within. 
Description of the caterpillars in both stages must be 
left for one more advanced in that respect than I am. 
However, I shall endeavour to give ‘an idea of what they 
are like. 
The young examples, before their change, are ege-shaped and 
almost quite flat, at first they are dull yellowish in colour, later 
they become richly pink, but change to pale pink ere they depart 
from their hosts. After emergence from the cocoons they are even 
more flattened, and not so broad in proportion to their length, which 
is greater than before, and the sides are nearly straight. The edges 
of the seginents are now formed like the teeth of a saw, and are
