98 MR. NEWPORT’S FURTHER OBSERVATIONS ON 
still further discoloured, and many of them were dead, and all were covered with the 
bladder-like bodies in greater abundance. 
On examining other specimens of these larvæ, which I had placed in separate bee-cells, 
I found that these also were in a similar condition; and on inspecting my collection of 
larv and pupæ of Anthophora, these too, to my utter astonishment, were covered in the 
same manner. 1 noticed also that the vesicles first observed on the larv in the glass tube 
had become much larger, during the past two days; and on inspecting them very carefully 
with a lens, I found that the bladder-like bodies were either the nidi of parasites, or living 
parasites themselves attacking and exhausting the enemies of the young bee, as the bee 
had been attacked by them (fig.5). Thus in less than eight days from the time when my 
specimens were collected, the whole were irretrievably destroyed by objects which now 
covered them in multitudes, but which at first were so microscopic as entirely to escape 
observation. As it was now evident that my whole collection of larvee of Monodontomeri 
would soon entirely disappear, I placed a number of them, together with the parasites that 
covered them, in spirit for future examination. Out of nearly two hundred and fifty 
specimens of these, and of a still greater number of larvee and nymphs of Anthophora, the 
result of the persevering labour of several hours’ search, I was not able to save even 
a single specimen. Wherever I placed them in the room appropriated to my investiga- 
tions, they became covered with these microscopic enemies, whether secured in wooden or 
tin boxes, or covered earthen pots. I now began to suspect the cause of this mischief. 
During the time I was collecting the larvze, on the 16th of the month, I found some bee- 
cells nearly filled with a large mass of vesicle-like bodies. These were completely new to 
me. ‘The body of the bee-larva seemed to have been changed into this mass of spherical 
nondeseripts (fig. 1), which, although quite distinct from each other, were aggregated 
together, and somewhat resembled a microscopic bunch of grapes. Each of the bodies was 
opake and clouded on its upper surface, and seemed to include other bodies. On its under 
surface it was clear and transparent. They varied greatly in size, from that of a minute 
pin’s head to nearly one-sixteenth of an inch in diameter. Having found several of the 
cells filled with them, I collected these cells, for the purpose of ascertaining, if possible, 
the nature of their contents. I found also one cell in which these bodies, as well as the 
remains of the bee-larva, were almost dried up. The instant this cell was opened and 
exposed to light, I noticed, on examining the interior with a lens, that it was partly filled 
with what looked at first like dust ; but more closely observed this was seen to consist of 
crowds of little brown objects (fig. 6), in a state of the most vivid and incessant motion. 
These were so exceedingly minute that I could only recognise them to be living creatures 
by means of the lens, and even then with difficulty, without being able to distinguish their 
ee of the same colour as the clay-soil of the nest. They reminded me
