REPORTS OF MEETINGS— 1900. 



Mondaj^ evening, Januarj^ 8. Regular meeting; fourteen mem-

 caddice-fly lar\^ae, a species of Gyrinus in considerable numbers, 

 also two of the H^-drophilidae, and two species each of the Dy-

 In a brook not far distant, the pebble building caddice -fly abounds 

 in the vegetable covering of the submerged stones, and they are 

 also abundant in similar situations in the brook which crosses

 material and food brought to them by the swiftly flowing water. 



At the conclusion of the paper and a brief discussion, the re-
