found, small inch-worms (Geometridje), about 0.15 long were 
hatched from them. The aphis-lion was at this time reposing at 
the top of the vial when one of these worms approached him. It 
was instantly seized, and the contents of its skin were sucked out 
with avidity, and he now commenced searching for another worm, 
probing every crevice in the cork stopper with his long jaws, and 
then walking down the vial, examining from side to side as he 
went along, until he came to the leaf at its bottom, now curled 
and Shrivelled. He first crawled through every fold of this and 
then wandered over its surface, till coming to another worm, it 
was instantly seized. Thus sixteen of these newly-born inch- 
worms were consumed as fast as he could find them. They were 
seized indifferently by whatever part of their bodies was first ac¬ 
cessible, and he was occupied four or five minutes in sucking out 
the fluids of each worm. As the skin became empty it was folded 
together, and rolled about between the tips of his jaws in a little 
wad, until the last particle of juice which it contained was ex¬ 
hausted. The skin was then adroitly wiped off from the tips of 
his jaws, and he started off in search of another worm, always 
carrying his head down close to the surface on which he was 
walking. Sometimes on coming to a skin which had already 
been sucked, it was taken up and rolled between the tips of his 
jaws again, as if to ascertain whether he had done his work well. 
When occupied in sucking a worm he stood still, adhering more 
by means of his tail than his feet, and there was a pulsating mo¬ 
tion to his body indicating the satisfaction he felt in the act in 
which he was engaged. If another worm approached so near as 
to touch him at this time, he gave a sudden spiteful shrug, where¬ 
by it was frightened away. Only three worms remained when I 
introduced into the vial a cocoon of spider’s eggs, with some of 
the young spiders hatched and crawling about the cocoon. These 
were immediately discovered by the aphis-lion, and leaving the 
worms he commenced devouring these small spiders in the same 
manner, each spider occupying him about half the length of time 
one of the worms did. The fine cobweb of the spiders appeared 
to adhere closely to his jaws, and to wipe this off, after finishing 
one spider, and before seeking another, he thrust his jaws repeat¬ 
edly into the cocoon. Thus quite a number of the spiders were
