MONOGRAPH OF THE NORTH AMERICAN PROCTOTRYPID.E. 429 



Abdomen oblong-oval, with a very short, thick, woolly petiole, the 

 second segment very large, occupying more than two-thirds its whole 

 surface, the following segments very short. 



Legs clavate, pilose, the basal joint of posterior tarsi about twice as 

 long as the second. 



Very closely allied to Loxotropa Forster, but the absence of the basal 

 nervnre at once separates it. 



The following table will aid in determining the species:
