We unite here a number of different-looking insects as forms of one species. 

 They agree in structure, as far as we have been able to study them. The material 

 is scanty in collections, but what we have seen confirms us in the belief that we 

 have to do with one variable species instead of five. We are the more convinced of 

 tlie correctness of this view, as individual variability in the amount of yellow is 

 illustrated also by S. inj'ernalis.
