NOTE. 



THE insects mentioned in these pages are those 

 that I have found by hunting in several brooks in 

 Alameda County, California. The fact of the 

 distance of my point of observation from the 

 places where most readers reside makes no espe- 

 cial difference, however, as members of the same 

 families of insects will be found in or beside al- 

 most any brook, East or West. The various types 

 of boy mentioned here probably exist in both sec- 

 tions of the country, also; and I will promise 

 those who go dredging in the Atlantic - coast 

 streams that there shall appear to them the ap- 

 paritions of both the " fat woman" and the "wan- 

 derer from Erin's isle."
