 foregoing except in the following details : The propodeum is without a 

 median carina; the mesopleura above the crenate impression is not 

 smooth but faintly coriaceous; the first abdominal tergite is not

 agrees well with provancheri but in that species there is a large 

 fusiform median impression on the posterior half of the mesonotum 

 which is apparently absent in luteiceps. 

 HaMtat. — Kansas. 

 Host. — Unknown.
