 D. H. Storer, Vice President, in the Chair. 



Dr. Wyman placed upon the table a specimen of the 

 mole-cricket, Gryllotalpa vulgaris, taken by him in Virginia. 

 This species takes its name from its habit of burrowing in 

 the earth, for which purpose its first pair of legs is modified 

 in form, presenting a striking analogy to those of the mole. 

 He exhibited this structure in detail. Dr. Wyman also ex-

A letter from Dr. Kirtland was read. 



Caleb Reed, and F. S. Ainsworth, were elected members.
