APHIS (pemphigus) stamineus. Hald. 



This name is proposed for a large species of Aphis, which 

 forms follicles on the leaves of the silver-leaved maple, (Acer 

 eriocarpum.)

Dr. Gould observed, in relation to the food of the 

 robin, which had been spoken of at the preceding meet- 

 ing, that experiments, conducted since midwinter, show 

 that its crop is found full of insects at night ; as many 

 as 500 have been found in a single bird. It is difficult 

 to understand how they get such a full supply in cold 

 weather.
