9. Toxoneuron abdominale. JV. sp.

 legs except coxae and trochanters, and the abdomen entirely pale san- 

 guineous ; base of first abdominal segment tinged with yellow ; wings

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 Braeon.
