9. TOXONEURON ABDOMINALE. JV. sp.

Illinois. Bracon populator (Say, Long’s 2nd Exped., ii, p. 323), which 
is also referred to this genus by Say, and which, he says, is “a very com- 
mon insect in many parts of the United States, does not appear to be a 
Toxoneuron, as the ovipositor is described as being longer than the 
abdomen.” It is probably a true Bracon.
