The insects falling in this tribe, in metathoracic and venational char- 

 acteristics, are most closely allied to the Anomalin!., and many of them 

 are easily confused with those of that tribe, since there is no sharp 

 divisional character known. 



The differences noted in the mesonotum (usually the absence of par- 

 apsidal furrows), the shorter, less distinctly (rarely strongly) com- 

 pressed abdomen, the shape of the petiole, and the normally thickened, 

 rarely incrassated, hind tarsi, must therefore be depended upon to 

 separate them. 



Sixty-five genera have been recognized in the group, most of which 

 occur in our fauna. At present many of these genera are represented 

 by described species wrongly placed in Llmnerla and allied genera. 



The following table will enable the student to recognize most of the 

 genera: j
