This species was bred by Say from a Sphinx larva, and must, 

 I think, be the same as that described by Fitch. The words 

 " radial cellule with the nervure as obvious as the others ; 

 second cubital cellule I'ounded destitute of the exterior nerv- 

 ure," in Say's description, might throw a doubt on his insect 

 being a Microgaster at all : but there is an inconsistency in 

 the second cubital cellule being open and rounded in the 

 same insect. No other small Ichneumonids are known to 

 attack Sphinx larvai in the manner he describes, the insect 

 mentioned in my first Report on the Insects of Missouri 

 (p. 96 note) as a species of Blacus, on Mr. E. Norton's 

 authority, being this common Apanteles. 



ensiger Say, Bost. Journ. Nat. Hist.,, i. 260 (1836). The open 

 areolet of the $ would place that sex in Apanteles^ but the 

 S is said to have the areolet closed. Say must have con- 

 founded two quite distinct insects.
