where I disturbed females the flies hatched ten and twelve in number, 

 respectively, and were all females. 



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 

 days before issuing. They issued from twenty to possibly fifty in num- 

 ber, although I was never positive of breeding more than thirty-eight 

 from one specimen. 



This parasite did much more good than P. puparum, as it seemed to 

 get the first chance. 



APANTELES CONGREGATUS. 



This insect was very destructive to the Sphingid larva? on tomatoes. 

 There were no less than four species of these worms, of which Macro- 

 glia quinque-maculata was most abundant. All were attacked, scarcely 

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

 of one worm.
