Miris affinis Reut., a member of another sub-family, (Mi- 
raria), is illustrated (Fig. 57) to show the form of such insects. 
It is sometimes decidedly common upon the heads of wheat, 
barley, rye, and timothy, and is there for no good purpose. If 
it should become more numerous it will doubtless cause injury 
to these plants, as the abstraction of sap from kernels just form- 
ing, and the introduction of poison, can be of no benefit.
