I was not able to take the females of A. glomeratus in the act of ovi 
positing, as they seem very sly. Several times I thought I caught them 
in the act, but was not sure. After pupating they were eight to ten

from one specimen. 
This parasite did much more good than P. puparum^ as it seemed to

This insect was very destructive to the Sphingid larvae on tomatoes. 
There were no less than four species of these worms, of which Macro-

any escaping. I took one hundred and eighty cocoons from the body 
of one worm.
