whole of their viscera and ultimately destroying their victim. The abdo- 
men of the beetles thus infested often presents so swollen an appearance, 
that a diligent observer may readily recognize them. Two, or even 
three of these worms, from one to three inches long each, are occasion- 
ally found in the body of one insect, and when developed, it appears 
almost impossible that they could be coiled in so small a space as that 
from which they have emerged. 
I have kept many of the worms taken from the Carabide in water, 
but they have uniformly died after some weeks, having during that 
time maintained a constant vibratory motion. After a tempestuous tor- 
rent of rain, which fell on a hot day in the latter end of July, my childrea 
brought me two of these worms, found in my garden upon the dripping 
leaves of an Arbutus tree. One of them was about two, the other about 
three inches long. They were both ina very vigorous state, and I im- 
mediately placed them upon some wet earth, in a garden-pot, with a 
glass over them and proceeded to search for a specimen of the Molops 
madidus that I might introduce it to the Gordiz and see what would fol- 
low. Having speedily found one of these insects I put it under the 
glass, and in less than five minutes the beetle attacked one of the worms, 
cut it in pieces with its jaws, and very quickly devoured it, pushing with 
its palpi the wriggling pieces of worm into its mouth, The Molops 
entirely devoured both the worms in about ten minutes. I kept this 
Molops, feeding it with flies and other insects for some days, when it 
died. On dissecting it Icould not discover any traces of the worms it 
had devoured. 
About the same time another worm of this kind was found, after a 
heavy rain, in the garden of a friend, which was presented to me. ‘This 
worm is of an amber colour and transparent, and when examined under 
the microscope its annulose structure is very distinct, the whole body 
being transversely striated. The intestinal canal appears filled with little 
well defined globular bodies of a dark colour, presenting the appearance 
of ova. This worm tapers towards the head, which is slightly tinged 
with a crimson hue; the orifice of the mouth can under a Jens be dis- 
tinctly perceived. The ova (if such they are) commence where the 
tapering off to the mouth ceases, and are continued to the anus, which
