Although this note seems to assume a good deal on rather imperfect 

 grounds, I feel sure that it approximates more closely to the true philogeny 

 of the insects under discussion than any of the groupings now current, 

 and I hope that it will stir up some research and discussion on this 

 fascinating subject.
